Golf IV / Jetta IV :: 2002 - Engine Works At 1100 RPM Whether Cold Or Warm All The Time
I have Golf MK4 1.6 16V BCB '02 and problem while engine is running on idle. Engine works at 1100 rpm (doesn't matter is it cold or warm engine) all the time.
Dashboard turns CHECK ENGINE and EPC lamps and says : "engine workshop". At the beggining of problem VAG-COM diagnostic found this error:
17953 - Throttle Valve Controller: Malfunction
P1545 - 35-10 - - - Intermittent
But after I've changed my old throttle body with new one VAG-COM diagnostic haven't reported any error (no permanent error) and idle issue stays.
While engine is running and Check engine and EPC lapms are turned on diagnostic reports this error:
17961 Barometric/Manifold pressure signals: Implausible Correlation
P1553-35-10 ----Intermittent
After engine is turned off diagnostic doesn't report any error!
Beside of changing throttle body, I've changed ECM, MAP sensor, temperature sensor, EGR valve, . Also checked intake manifold and hoses if is it leaky (doesn't leak anywhere), and timing belt is ok and checked complete wiring installation!!!
Toyota - Corolla :: 1996 - Misfiring After Hard Start
About a month ago I went to get into my car and it would not start. It tried to but after testing things with my neighbor there didn't seem to be consistent spark. So I bought a new distributor. Got it installed and the car worked great. Then after about a week we had a heavy rain while I was driving. The car shut off and wouldn't start. After the rain was over for about an hour I went to look over the car and it started. I thought with the heavy rain something got wet. Then things really went down hill. A day or so later when I went to start the car it didn't want to start and when it did it would misfire. Later that day the car started fine but would only run right if the engine was warmed up.
I tried covering the car completely with a tarp, no change. My cousin who is a skilled mechanic said he was pretty sure that the issue was the new distributor. So I got a used one, not wanting to pay another large amount again. Put that in the car and no change. So I pulled the plugs on the car. Plugs 1 and 4 had a heavy carbon build up on the tips with pitting in the carbon. I had had them replaced, with the wires back in October. So I replaced the plugs and coated the wires in liquid electrical tape. Car started fine like it does in the afternoons. Nest day it was raining and I went to see what the car would do. It started! I drove it that day with no issue at all. The next day I went to start the car thinking my issues where over. The issue has returned. I changed out the plugs with new ones that night. Car started fine that night. Next day the car is still not wanting to start and misfires when it does. It has been damp but covering it doesn't change anything.
Chevrolet - 1500 :: 1996 Chevy Engine Hard To Start When Cold
I have a 1996 Chevy Cheyenne pickup with a fuel injected small block that has 50k miles. Earlier this summer the truck developed a problem where it is very hard to start when cold (after sitting overnight or after sitting for many hours on my flat driveway). When the engine is cold (say the first start of the day) I can only get it to start by giving small bursts of cranking power to the starter. That is, it won’t start if I hold the key in the cranking position but is more likely to start if I give it a short burst of cranking power (when I hold the key in “start” position) for a second or two.After the first start of the day, the engine runs fine and subsequent starts are quick and normal. The “Check Engine” light is not on and there are no trouble codes…. Other than hard starting there are no issues with engine performance.

I have issues with engine starting when cold outside or after rain. This only happens when engine is cold and has not been started for a day or 2. Distributor cap does not have any condensation inside but does seem to corrode on contact points. Engine turns over fine, has fuel and spark. When this happens engine will not fire and after awhile it will start to fire and lock up when it fires then continue cranking. After repeated attempts it will start and run fine, can be shut off and start right back up with out any issues. It could take a few tries to a few hours of trying before running though. I'm leaning toward a distributor or timing issue. Am I on the right track? 98 Suburban K1500 5.7L ....
View 6 RepliesFord Excursion :: 2001 7.3 PSD Extremely Hard To Start When Engine Is Cold
Truck runs great if I get it started. Here are symptoms.
-Extremely hard to start when engine is cold
- It will start fairly quick if plugged in all night
- After running there is no issues with starting unless sits over night
- Batteries good and engine cranks fast
- Tests and parts I have replaced
- Replaced GPM (Glow Plug Module) I do not have the relay as most seem to have on their engines. I did replace this unit.
- Replaced Glow plugs all 8 this morning. Since they where cheap enough it did not hurt the wallet.
- Replaced crank position sensor. Tach moves when engine is cranking.
- Checked the HPOR and it has oil about 1/2" from top.
Now what is left to check besides doing a buzz test to rule out injectors? Also if truck runs fine and does not run rough could injectors still be bad?
Ford - Explorer :: 2000 Won't Idle When Cold / Hard To Start And Keep The Engine Running
I have a 2000 Explorer W/4.0 SOHC engine. With summer nearly over and fall on the way, I need to figure out what is going on with my engine. This problem has been going on for the past 2 years. As the outdoor temperatures get cooler, the harder it is to start and keep the engine running. This starts happening around 65 ambient temperature, and gets worse as the temps drop. By 30, I can barely keep the engine running.
Odd thing is, all I have to do if the engine starts is, keep my foot on the pedal to keep the engine around 2000RPM, put it in gear and start driving. After about a mile or two, the engine runs normally, and will do so the rest of the day. So far I have cleaned the air flow sensor, replaced the IAC, replaced all the injector "O" rings, and cussed a lot. I smoke tested the engine and the only vacuum leak is a very small one at the EGR valve.
Touareg :: Misfiring While Accelerating From A Cold Start
For the past few weeks, my Treg has been misfiring while accelerating from a cold start. It only does it when the engine is first started and only the first time you accelerate. Also blows blue smoke out the tailpipes while this is happening. Car is at the dealership right now with a tech and Service Manager scratching their heads. I already did a search for my problem, nothing matched it.

2003 F350 7.3L 164k miles. Got towed in with hard to start cold complaint.
Hooked it up to the Snap On Verus Pro scan tool and we get up to 3000 psi on the ICP cranking, IPR value seems within spec, we have rpms over 100 on tool, pulse width within spec, computer voltage above 10v while cranking, verified output of glow plug module (California) and glow plugs get voltage for approx 50 seconds @ 80 degrees farenheit, glow plugs all read 0 ohms resistance.
injectors do NOT sound the same during buzz test.
Vehicle takes EXCESSIVE cranking cold to eventually get it started. LOTS of cranking. Just had to replace starter and a battery because driver burned em out. It feels like the vehicle shakes when it gets running. Black smoke when revving cold. Sometimes white smoke while cranking.
Once the engine has been warmed up, it starts perfectly every time.
I have spent two days in the engine bay looking for chaffed wires and doing diag and my current diagnosis is bad injectors. I feel there COULD also be high pressure oil leak, or a mechanical issue such as low compression. No compression guage yet for this truck. We have the ICP and IPR fittings to do a shop air test. Recently did a 6.0L and went thru everything and eventually diagnosed it as bad HPOP. LOW ICP pressure.
I noticed two of the cylinders were at maybe 8% Perdel on the data. Seems too high. Also, it "passed" the KOER self test and "passed" the injector buzz test with no codes after, but the audible sound of injectors didn't "seem" right to me, but I am new to these engines.
Ford 6.0L Power Stroke Diesel :: 2003 - Hard To Start / Misfiring At Around 30% Throttle Driving
03 6.0 with 90k miles. New heads, all orings , stand pipes, injectors , glow plugs, egr delete , oil cooler and studs . Has sct livewire. Just took the truck to the shop for a hard start issue and misfiring at around 30% throttle driving. It would fire up great in the mornings with some white/blue smoke till warm. But after it was warmed up you shut it off it would fire right back up but very slow to reach proper idle.
But if it set for about an hour it would crank great start but same lazy idle up but now it wouldn't get over 300 rpm before it would die. And do this for 5 or so more times before finally idling up. Then runs pretty good other than the misfire. So he said it's either the hpop ipr or icp. I had him replace all 3 with motorcraft parts. Still the same issue ! Return the truck to stock tune and it doesn't have any power . My pockets are only so deep...
Ford 6.0L Power Stroke Diesel :: 2006 F350 Shut Down / Stalled / Misfiring And Hard Start
Fuel injectors do this? They are off a 2006 Ford F350 dually with the 6.0 diesel motor! Have replaced all 8 fuel injectors got back drove for 200miles and fuel injectors 4 and 8 were throwing codes changed them out and high pressure oil pump oil coolant deleted egr valve changed the ipr valve feed tubes to the oil rails. replaced the FICM. Yet again drove for 2 days about 200 miles again and shut down (stalled) misfiring hard start. and now fuel injector 4 is throwing codes again. Have not drove it since we got it home from the last stall out which was a few feet from our drive way and we towed it home.

View 2 RepliesTiguan :: 2011 SEL Whine On Cold Start
My 11 SEL is making this weird noise on a cold start. It sounds like almost like a bit of brake squealing when I first turn the steering wheel. I am not touching the brakes so I don't think it is that. Only lasts for 2-3 seconds and then it is gone. The car runs fine otherwise and there is nothing felt in the wheel.
View 1 RepliesTiguan :: 2014 - Ignition Rattle On Cold Start
So I am hearing a weird noise when I start up my Tig after it's been sitting at least overnight. I'm not sure when it started because if the windows are up when I start I can't hear it inside, so for all I know it's been happening since before the warm weather arrived. But anyway... It's a brief rattle, kind of high and plastic-y, like maybe a half-second long or less, when I first start up. If I turn it off and then start it again, no rattle. Don't hear it again until the Tig has sat for a while.
No CELs or anything or other signs of trouble. It's a 2014 with 24k miles, bought CPO at 19k.
Tiguan :: Running Rough During A Cold Start / Random Cylinder Misfires
I've got a 2009 Tiguan with 65k miles on it. A few weeks ago I noticed some issues with running rough during a cold start. I only noticed because the engine would vibrate considerably more than usually for the first few minutes of operation, and would idle at around 1050-1100rpm instead of the usual 750rpm. After warm up, things were fine. Suddenly the issue got bad real fast - wife was out and the MIL light came on, EPC light came on, and the car was running extremely rough. We managed to drive it home (2 miles) doing under 20 the whole time on side streets. Once I hooked it up to my OBD reader, I was seeing cylinder misfire codes on all four cylinders.. P0300, P0301..P0304, all five codes simultaneously.
Since the car was due for an oil change and hit 65k miles recently, I decided to throw new plugs in there to see if that would work. It did, at first.. A day or two it ran completely fine, no rough starts, no misfires, I thought I had solved the problem. The old plugs had some deposits on them and were original, so I thought I was in the clear. Two days later, same thing happened again.. EPC light, barely running and misfires on all four cylinders..
I read up some online and decided to order new ignition coils. Took a few days, but I got four new coils and threw them in. Again, problem solved it seemed. No more EPC light, misfire codes didn't come back and no more rough starts. I drove a good 40 miles with no problems at various speeds, but started noticing some misfires during acceleration (slightly rough acceleration, almost feels like a back and forth rocking motion, very slight). Sure enough, after a cold start I'm seeing the engine run a bit rough again with misfires. This time, only P0304 (misfire on cylinder 4) is thrown, and it only shows up as a "pending code" (engine light flashes for a few moments during start, but does not stay on).
I checked my connections, swapped the plugs and coils in what I thought were cylinders 3 and 4 (closer to the driver side), nothing. I swapped what I think are cylinder 1 and 2 (passenger side) just to be sure, but still nothing. At this point I'm pretty lost. I know enough to be dangerous with a carbureted engine, but am lacking in knowledge when it comes to a fuel injected turbo charged VW engine. It seems to be cylinder 4 misfiring consistently at this point according to the OBD reader.
Also of note.. I had some misfire problems last year, and had my intake manifold replaced as part of a recall (also had carbon deposits removed at the same time). Can a carbon build up occur this fast? Can it be the injectors?
Ford Super Duty (1999-2016) :: Cruise Control Works Only When Engine Is Cold
I have a 2000 f250 7.3 and the cruise control works when only when the engine is cold. Once the truck warms up, cruise will shut off and not reactivate. I have no lights on on the dash new clutch safety switch a new sensor on the master cylinder horn works and have had a scanner hooked up and compared the electrical values of the buttons pushed to the spec.
View 3 RepliesGolf IV R32 :: If Rev At Start Up Car Will Idle At About 1100 RPM
Recently, my car has been having issues starting. It will start if I get a boost, but will be dead if I turn it off again. Also, while I'm driving, the airbag, ABS, and traction lifts all come on, and eventually my radio will shut off, but after a few minutes the radio will come back on and the warning lights will go off. When i first start the car it idles as it should but if I rev it will idle at about 1100 RPM. What might be causing all of this? Battery? Alternator? Or EPC?
View 7 RepliesFord - ZX2 :: 2001 - Hard To Start / Feels Like Not Getting Gas Upon Cold Start
I've been driving my wife's 2001 Ford ZX2 for the last ~9 months.
Early on in taking over driving it I noticed that it was difficult to start, so I had the battery checked. One place said it need to be replaced, but I wanted confirmation so I had it checked at two other places--it was in the normal range. So then I thought it probably needed a tune up since, as far as I know, it had never had one (has ~50K and I know it should've been done earlier). But, that didn't seem to fix it either.
I then had the fuel filter replaced. Nothing. I generally turn the key over for a few seconds before I actually crank it to let fuel in. It is now taking 3 times each startup to do this. And, right after starting it feels like the car is struggling to get gas (as if the fuel filter is completely stopped up or a fuel link is kinked).
Once the car is warm it cranks over on the first time (as if nothing is wrong). The last time I was at the shop they told me I need to have my fuel injection system cleaned. I have doubts about this--they based it on mileage not any sort of actual diagnostic or inspection. I use quality gas and run a fuel injector cleaner at each oil change.
Ford Super Duty (1999-2016) :: Hard To Start When Cold - White / Grey Smoke At Start Up?
Truck: 1999 Ford Truck F 350 4WD Super Duty V8-7.3L DSL Turbo VIN F
Problem: Especially when it is cold outside . . . The truck takes forever to start and while doing so a ton of white/grey smoke comes out of the exhaust.
My starting schema: Turn the key on have the gas pedal pushed to the floor until the "wait to start" light goes out. Then, I turn the key off and back on while still pressing the gas pedal all the way down. When the "wait to start" light goes out again I remove my foot from the pedal and try to start it. I never leave it cranking for more than 5-7 seconds. If, after trying this process several times I will not push the pedal in at all. Also, sometimes I will leave the pedal pushed in while I am cranking it over.
The truck used to start after a couple of tries but lately it won't start at all, even after 20 tries. Sometimes it will spin up for a second as if the engine gets going but then just doesn't continue running. When it is warm out it will usually start after a few tries but doesn't seem normal to me. After I first bought the truck(used) it would start up within half a second after turning the key.This all started after I had to fix an o-ring that was damaged on the top/back of the motor that was dumping all my oil out of the top/back of the motor.
Jeep - Liberty :: Engine Misfiring When First Start Out And Then Runs Smoothly
My engine seems to misfire when I first start out and then runs smoothly. The first mechanic got a random misfire from the diagnostic and replaced all the cylinder coils which worked for about a week. The second mechanic ran a diagnostic which said random misfire and he said it was a loose spark plug. This worked for 4 days then it started misfiring again. There's no violent shaking or backfiring. I don't know much about cars but it seems odd that it doesn't keep misfiring. It's a 2006 jeep Liberty with 87,000 miles...
