View 1 RepliesMetro :: 2000 - Rough Idle Along With Engine Shake
4 cyldr has very rough idle along with engine shake. Just started doing this. I replaced the cam sensor a few months ago and all has been well. But it started running so rough, almost like it jumped time. I was disconnecting sensors to see if motor idle changed and when I unplugged mass air flow sensor on air filter intake tube, nothing changed. Could this cause such a dramatic idle ?
View 2 RepliesPassat (B5) :: 2000 - Bad Motor Include Rough Idle / Oil Leakage / Coolant Light Comes On
I just got a 2000 Passat 1.8T with a bad motor.
Symptoms include: rough idle, oil leakage, coolant light comes on after running for about 2-3 min., I checked the coolant res. and it has what I suspect is oil in it. I know that the PO ran cheep oil and oil filters the last 2 oil changes and this has caused the famous cannibalization of the engine but what I need to know is would this feed oil into the the coolant over flow tank? There also seems to be some oil/coolant seeping from the upper left.
The car only has about 90k on it and most of those are highway miles, other than cheep oil, the car has been very well taken care of.
Golf IV / Jetta IV :: 2000 - Rough Idle - Flashing Check Engine?
The check engine light came on in my 2000 Jetta and the engine power suddenly decreased noticeably. Got worse quickly and was idling rough, like it was about to stall out (but didn't). Took it to dealership, they said spark plugs were the problem and replaced. All seemed normal driving home, but after 10 minutes, same problem: check engine flashing, weak engine (trouble on hills), and a rough idle.
Two questions: what could it be?
and is it safe to drive back to dealership (~10 miles) or might that cause further damage?
Passat (B6) :: Engine (MIL) Light On - Very Rough Idle
When exiting off the freeway and stopping at the light, my car felt as though it was bucking and idling very rough. I put the car in Neutral and it subsided a bit but the lit gauges were pulsing with the idle. It felt as though the car was going to die. I put the car back into Drive and it drove fine. I pulled over and shut the car off. There were no warnings or any other indicator lights on during this time. After shutting the car off and leaving it for a couple mins, I started it back up and the engine light was now on steadily. The rough/bucking idle was present as well. I ended up driving the car to the dealer where it is now being diagnosed and I haven't heard back.
View 6 RepliesAccent LC (2000-05) :: Rough Idle - Engine Get Louder And Car Starts To Vibrate Slightly
Recently bought a 2001 Accent that has been experiencing a 'rough idle' for the last few weeks. Basically, after I've driven the car for a few minutes (from a cold engine position) and then stop at a stop light or stop sign, I can hear the engine get louder and the car starts to vibrate slightly, after I've driven for about 15 minutes at higher speeds and then stop again I can actually see the steering wheel shaking when I take my hands off of it. If i put the car in park when I am stopped and the engine is on, the idle calms down quite a bit. The weird part is that when I first start driving the car in the morning, the rough idle problem doesn't happen until about 5 minutes of steady driving - so when the engine is colder I don't experience the problem, The problem is not that serious, and Ive already brought it into a dealer who cleaned out fuel injection, gave me a major tune up and replaced all the spark plugs, but the problem still persists. I am gonna bring it back to them but they seem a bit lost to be honest. Other than this the car is driving normally when I am not idling.

View 2 RepliesFord F-150 - 1997-2003 :: 2000 V8 Running Rough At Idle And Check Engine Light On
I started out with my 2000 F150 with a 5.4 V8 running rough at idle. It would idle way down slow and then rev up a little over and over. On a couple of occasions it would even die when in drive or reverse. I did finally get a Check Engine light so i put it on my diagnostic program to see what was up. Here is what I got:
P1151 Lack of HO2S21 Indicates Lean
P0171 System Too Lean Bank 1
p0174 System Too Lean Bank 2
After doing some reading up I checked all my vacuum hoses and cleaned my mass air flow sensor. I then got the same codes again after a few minutes of running. So I went to the next thing that was recommended, the upstream bank 2 O2 sensor. After changing it the truck ran fine for a couple of days, no issues. Then all of the sudden it idled a little funny again and I got a Check Engine Light again. This time:
P0171 Bank 1 Lean
P0174 Bank 2 Lean
P0300 Random/Multiple Misfire
I reset the light to see if I would get the same again later. Before the light came on again I filled my truck up with gas and it seemed to be running pretty good again. Then a day or so later it set the light again. This time:
P0171 Bank 1 Lean
P0174 Bank 2 Lean
P0136 O2 Circuit Malfunction Bank 1 Sensor 2
P0156 O2 Circuit Malfunction Bank 2 Sensor 2
P1131 Lack of Switches HO2S11 Lean
P1151 Lack of Switches HO2S21 Lean
I went ahead and drove for a few days as it had gotten really cold here and I didn't feel like messing around in my shop since it isn't heated. A couple days ago I needed gas so i filled up again. Suddenly the problem was gone again. Truck ran fine idled fine no missing or odd idling at all. That lasted a day or two before it started acting a little weird again. At that point i was down about 1/8 of a tank from full. I have read that there can be issues with the fuel pump.. I am kind of wondering if that may be it now. But I haven't had to deal with this sort of issue before so I am unsure what to check next. The truck always runs fine off idle, it only seems to have the issue when it is idling. I had reset the codes the last time and i have the light on again now. I haven't checked it yet but I am sure it is going be some combination of what i have had in the past.
I have read that the IAC valve can be an issue as well. I had a problem with mine sticking a couple years ago and when it would do it you could just tap it with a wrench and it would idle up. But it never died like it does now and it would also idle a lot slower than it does. Back then I cleaned the valve and had no more issues with it. The truck has always had times when it would act weird at idle usually after slowing down after being at highway speed. The current issue happens at all temps cold or hot.
Passat (B5) :: Engine Rough Idle - MAF / O2 Codes P0103 And P0134
I bought a 1999(b5) passat, 1.8t(AEB) 5spd, came with a DIRTY K&N so i cleaned it with the cleaning kit....
Car drove fine, then: started it up after an hour or so.. it was idling rough, then would spike(17-1800), idle rough, idle fine, spike....etc. just random. it went away for a few minutes, so i tried to drive it home... got 1/8 mile into 3rd... and car just bogged down so i slowed to stop and turn, went to go, it was idling rough so i couldnt drive, just "hobble" into parking lot.... i let run, more random rough, spike, fine... so i let it sit, off. when i returned, it was the same, but now CEL light on...
Codes: P0103 - Mass or Volume air flow sensor circuit high input
P0134 - Heated Oxygen sensor - bank 1 sensor 1 (H02s11) sensor circuit no activity detected
Yukon :: 1999 - GMC Suburban K1500 5.7L Misfiring / Lopes At Idle / Stumbles Under Load
I had to choose the Yukon, as there is no Suburban?
Anyway, I have a very bad misfire in my truck. Lopes at idle stumbles under load. Through substitution, I have tested: module, coil, and crank sensor. I have replaced: plugs, wires, cap, rotor, air filter, fuel filter and upgraded from SCFI to MFI (can you say "expensive best guess"?).
Still getting P-0300, P-0302 and mostly P-0304, using a Snap-on Modis scanner.
Compression tested today: all cylinders between 160- & 170 psi. After this, leak-down seemed redundant.
Back pressure test: 0.5 psi at 2500 RPM, both banks.
Steady fuel at about 60 psi.
I am going to pull distributor (175K miles) and examine drive gear. Not too sloppy at rotor bearing. However, how do I set baseline timing when I re-install distributor? If the distributor is OK, what test or part should I look at next?

After looking around online found out it could be a variety of reasons... gonna change spark plugs tomorrow hoping that's the problem... next cheapest fix would be the ignition coils... I'm just hoping its not internal, like piston or rings.
It's a 2007 Passat Wolfsburg 2.0T.... just went over the 53k mark.
Passat (B5) :: Rough Idle And Noise From Engine Around 4000 RPM - P0011 Code
I now have a p0011 code on my 2001 passat 1.8t aug. this is a thinker because right before the test drive around the block i did the following
- coolant flush
-replaced the fuel filter
-cleaned the knn air filter
-rotated the tires
-oil change with new castrol 5w-40 syn. and 1/2 a bottle of lucas syn oil stabilizer.
With a few phone calls a possible cause is the timing chain skipped a tooth cause of the lucas being to thick, other cause could be the tensioner finally went out?
Right know the car car has a rough idle and seems to be finding idle , and a noise from the engine around 4000 rpm.
I am waiting for the engine to cool off before i open her up to check timing.. if the chain is off a a tooth what could be the cause?
Passat - Volkswagen :: 2001 - Engine Warning Light On / Very Rough Idle
The 2001 Passat 1.8lT has an engine warning light on and feels like it is running on less than all four cylinders.( very rough idle) This is the first time we have seen this particular warning light and the manual suggests that it has a problem with the catalytic convertor.( 170K miles on the car) The car had no symptoms until the light came on today and the car was serviced last week. ( oil change and new tires) It seems that every time I take the car in for service something goes haywire shortly afterward.
View 6 RepliesMazda - Protege :: 2000 - Won't Start / Sometimes Sputters And Lopes Before Just Stops Firing
I have a 2000 Mazda Protege LX with 38k miles on it and a 1.6L engine and it starts fine in the morning to go to work and starts fine in the afternoon to go home from work. If I get home and change clothes, hop in the car to go somewhere, it won't start, turns over like it's out of gas, sometimes sputters and lopes before it just stops firing. It seems to only do this in the afternoon, specifically between 3pm and 5pm, never after dark or in the morning. I can drive all day long as long as I don't cut off the engine.
After sitting for about fifteen to thirty minutes, it will start like nothing ever happened. So far, it only does it once per day. After I get it started in the afternoon, I can seem to go anywhere, stop as many times as needed, and it keeps starting every time. It seems to be getting more frequent as the weather warms, never did it in January or February, but so far has done it every time I try to start it when the temp is around 80 or higher. I get no engine light, temp gauge is normal.

Wifes car began to idle very rough and check engine light began to blink and beep, I took it to the mechanic today and he informed me that my control module was no good and it was a $400 dollar piece. I said go ahead get it done, cuz she needs the car and i couldn't afford to not have it done immediately. Question I have is does this small-ass piece really go for that much on average and what control module is it?
View 4 RepliesFord 7.3L Power Stroke (1999-2003) :: 2000 - Lopes At Start Up When Started Cold
I recently purchased a 2000 7.3, when it's started cold it's lopes at start up unless I give it some gas and then it's perfectly fine. If the truck is plugged into the engine block heater it starts normal. I changed the oil the day after I bought it and put 15w-40 in it and then the rough idle started. So I don't know if it was like this before or because of the thicker oil I put into in the cold. It also has a service engine soon light on and the code that comes up when read is to the icp sensor. When looking st the sensor the blue wire going to it looks cut and is disconnected. How would I reconnect these wires and see if that makes the check engine light go off.

My engine will occasionally lope at startup. If I look at my scanner the fuel trims will suddenly go negative up to - 20 and then the engine smooths out. It seems to happen in open loop and when in closed loop the fuel trims balance out. I changed my maf sensor, but it did nothing. I don't smell any gas, no Check engine light.

Grand AM :: 2000 SE Rough Idle And Sounds Like It Might Die
I have a 2000 pontiac grand am with a 2.4 L engine it is automatic transmission. Th issue is i just bought the car from a lot thinking it was an easy fix. What happens is when i start the car it goes from a 1k idle to a 500 or lower and sounds like it might die or if i am at a stop light and decelerate too fast it also feels like its going to die and has a few times unless i keep the gas pedal pressed down. I read the codes at my local store they said it was a engine misfire, o2 sensor the front one, and the map sensor.
My farther works at a pull and save which is a lot to pull used parts from cars hes brought a used ignition coil, used boots , i bought new spark plugs and nothing was fixed there. we have replaced the maf sensor and the map sensor both with used parts neither fixed the problem. I am at my wits end here i cannot afford to take it to the shops around here and am trying to get this fixed to get back and forth to work. I may have left out parts that have been replaced, also as far as lights are concerned the check engine soon light is on .
