View 5 RepliesSubaru - Legacy :: Slight Rough Running With Cold Engine And Stumble Below 2000 Rpm / CEL Misfire Code
I have had some slight rough running with a cold engine and stumble <2000rpm. Finally it tripped a CEL which was read as a misfire code.
The mechanic swapped the coil and plug(recent) and no change. He did a compression test and air blew out the exhaust. So.......the car needs a valve job which entails motor removal and fixing the head and reinstall. He rough estimates this at $2000 and rate is $65/hr.
He mentioned looking at pistons and may be a bit more if rough.
This car well maintained (170,000 miles 2005 Legacy turbo wagon with manual)...
Lumina :: 1990 Chevy Just Stopped Running While Driving At About 55 Mph
So about 3 weeks ago, I was driving down the road at about 55 mph, on cruise control, when my car just started slowing down. I looked to see all of my dashboards lights on and I realized my car was not running. I shifted into neutral and the car started right up again, but when I pushed on the gas it just kind of stuttered and shuttered before dying again. When I came to a stop, again the car started right up, but repeated the shuttering and hesitating when I pushed on the gas and tried to get going again.
So, I repeated, but this time i just pushed very gently on the gas, getting up to between 5-10 mph before the car died again. At this point, it just stopped running completely. The engine would turn over, but would not keep running. When I got it into the shop, the mechanic said they put a fuel pressure gauge on there and the readings indicated that there was plenty of pressure, no problems the fuel pump or lines.
After further research, the mechanic said he thought it was an electrical problem, that it could be the crankshaft sensor or the ignition switch module, but he just did not really know for sure. I had him replace the crankshaft sensor, since it was the cheaper part, and it didn't fix the problem. So now I am just kind of stuck on what to do here.
Passat (B6) :: Engine Running Rough And CEL On - Misfire On Cylinder 2 And 4
I'm having an issue with a 2008 Passat 2.0T. Engine ran rough one day and check engine light came on! I get the VagCom out, scan the ECU and get misfire on cylinder #2 and #4. Car has 109 000km. Plugs were never changed so I order some new OE Bosch platinum iridium plugs. Go for test drive after having change the plugs and I still get misfire on both cylinder number 2 and 4.
I know coil on plug are prone to be weak on those engines so I go ahead and order 4 new coils which are pretty low cost which is good. Once install on the car I go again on a test drive. car ran really smooth and no check engine light came on. I said fine! I fixed the problem only to discover the day after that the CEL decide to come back on I scan again and this time only get misfire on cyl #2 with fault frequency of 39.
I suspect my injector to be bad but before I decide to remove the intake manifold and spend another 2-300$ in parts. Any way to test my injector with VagCom in order to see if that really is my problem. Also heard the PCV could be a problem but i hardly doubt it would throw a fauly code on just one cylinder.
Avalon 2005-12 :: Misfire And Check Engine Light Came On - Car Is Running Little Rough
My check engine light came on in my 06 toyota avalon. i had the code read at pepboys and they said it was something like 0300 misfire. i took it a few days later to my personal mechanic and he said nothing popped up when he tested the code. i notice the car (engine) is running a little rough though. What is the firing pattern as i want to try and fix by putting new plugs and coils.
View 1 RepliesCelica :: 2000 1zzfe Engine Was Running Rough - Cylinder 1 Misfire
Okay so last year i bought a 2000 celica gt manual with 50,000 miles, and currently has 67,000 miles. A few days ago I started to notice the engine was running rough and then about 10 miles later the chack engine light came on. I promptly went to the auto parts store to read the code. I was informed I have a cylinder 1 misfire. Naturally i replaced the spark plugs with NGK iridium, reset and rechecked engine code. Same code. Next i swapped the coils from 1 and 2, reset and rechecked. same code. I then swapped fuel injectors from 1 and 3, rest and rechecked. Same code. So now i am a bit stumped.
Only faulty equipment prior to this incident would be 2nd gear synchronizer. Only applicable above 5,800 RPM.
Ford - Mountaineer :: 1998 - Running Rough / Engine Shaking Like A Misfire
98 5.0 last week i was driving around for a few hours and everything was fine. Did some work in the garage for a few hours and had to run to the hardware store. Started the truck up and she ran like crap. Engine shaking like a misfire. First thought plugs and wires. Well by then it was late and Easter was the next day didn't get to it till Monday. Well after the change still crappy running.
So I changed the fuel filter and cleaned the mass air. No change. Checked for spark on the coil packs all have spark. Checked the PCV all good there. Checked for vac leaks none found. During that I noticed a small hole in the EGR tube I repaired that but still running like crap backfiring out the exhaust, engine shaking badly at times. I also changed out the FPR on the fuel rail. No change of course.
As of today I changed the coil packs. Again no change. Only code it throws is a EGR high flow after I fixed the hole but was having problems before that.
Chevrolet - Lumina :: 1992 Running Rough When Hot And Cutting Off At Stops
My main top water hose burst. I replaced it. Car ran hot. Replaced the thermostat, coolant sensor, and 12 volt relay fuses for primary and secondary fans. Still ran hot. Fans not coming on. I tested fans in service mode by paper clip to F and G in the diagnostic scan box. Fans came on, so no blowed motors. Got desperate, so ran a toggle switch to primary fan, so fan would run while I drive. Still, when the car gets hot, after about 5 miles of regular driving, the car huckabucks, and cuts off at slow downs and stops. Really bad in the middle of light intersections.

Elantra MD (2010-15) :: Running Rough / Check Engine Light Came On And Misfire Code
In the last month, my car has had an awful time starting on 2 different occasions. The first time it ran really rough for about 1 minute then was ok. The second time was the same but the engine light came on. Took it to an out of town dealer and he said it showed a misfire code but could never find anything else and all looked OK. Spark plugs?

View 6 RepliesDodge - Durango :: 2003 - Code P0300 Random Misfire / Engine Running Rough
Just started getting a p0300 random misfire code on the durango a couple days ago. pretty sure it isn't moisture related since it started on a nice sunny day. it was running pretty rough so it was obvious that it was misfiring. I changed the plugs since it was about time anyway, and they needed it and I cleared the codes. new plugs (put in the oem champion copper plugs) didn't make the problem go away. The engine still ran rough and the code came back. 2 of the plugs looked like they may have been fouling a little bit. they were a fair bit blacker than the rest of the plugs. I went ahead and changed the coils on those two cylinders and reset the codes again. Still runs rough and the p0300 came back. where do I go from here? I am not getting any specific cylinder codes so it makes sense to me that it isn't one or two cylinders not getting spark. 2003 durango 4.7 ....

View 4 RepliesSierra :: 4.3L Running Rough When Cold - Engine Is Missing
We have been having issues with my son's 97 Sierra running rough when it is cold/damp. It feels like the engine is missing.
Today, which is warm and dry, it started running really bad and it was all he could do to limp it home. It seemed like it wanted to idle fine but when he tried to rev it up the tach would start jumping and it seemed like it was missing.
Could this be a bad cap/rotor? The engine has 200,000 miles and we've never changed the cap/rotor. I changed the plugs/wires probably 100,000 miles ago.
Golf/GTI VI :: 2009 GLI - Running Rough / Engine Seems To Chug A Little When It Was Cold
About a week ago I purchased a new K&N air filter for my '09 GLI (6spd stick & all factory options with 55,000k on the odometer). Outwardly the vehicle seemed to run better (although a new clean air filter of any type will make a vehicle run better) however, 2 days later I noticed that the engine seems to chug a little when it was cold. Not missing like a plug wire off but a chug where it surges forward then holds back continually until the engine warms up. This persists today. I've also noticed a little bit of a rough idle. I've re-inspected my installation and nothing seems to have come loose and the filter fits perfectly.

My fathers 1990 GMC Sierra 1500 Pickup Truck 4.3L runs fine when it is cold but as soon as it warms up it starts running rough then stalls and won't start. There is no spark when it dies. As soon as it cools off it starts back up and runs fine till it warms back up.
View 2 RepliesFord Ranger / B-Series :: 1990 - Rough Start - Running Lean?
]I recently bought a 1990 ford ranger with a 2.9 @187,000 miles. That being said I went through and changed a few vacuum lines, the oil, air filter, pcv/grommet, and fuel filter.
The problem is it hates to start. I could crank on it for 10 seconds and not a single thing. Sometimes if i turn the key to the off position, wait a second, and try again, Ill get the truck to fire. When it does fire up it just reeks of the lean exhaust. It also gives me some hesitation when I rev it. I did a fuel pressure test (KOEO) last night and it gave me 32 psi and within a minute the needle fell to about 25 psi. I hear the fuel pump run for only 2-3 seconds too.
I've already pulled the MAF off and cleaned it, replaced the TPS, and did a fuel pressure test. The fuel filter is brand new
Start - Chevrolet - Lumina - Sparkplugs :: 1990 Sedan Won't Start / Engine Die When Pushed Down On Gas Pedal
1090 Lumina Sedan 3.1 ... First time it had starting issues Recently. About 2 months ago my lumina's engine would die when i pushed down on the gas pedal. After 2 days of trying to fix the issue it wouldn't start at all, i replaced:
TPS
MAP/MAT Sensor
Fuel Filter
None of these worked so i sent it to a shop, they replaced:
ECM
Multi Port Injection (All 6 Injectors)
TPS (even though i had just installed a new one)
Serpentine Belt (it broke when they were test driving it after the Repairs were done)
The car would not start even after they replaced the first 3 parts on the list, so the tech looked further at the engine and found frayed and open wires, on the bottom near the front side passenger door, he repaired these wires and the car started and ran.
The only issues i had after their repair was a rough idle while braking and/or when i was at a full stop, the rough idle went away after a few days of driving.
((Current No Start Issues))A week ago i had what i am guessing is a few electrical issues: Speedometer Twitching and then dropping to nothing while driving, temp and oil light popping on and then off, when the engine was at a good temp and the oil was fine when i had checked the day before.
I went out a few days ago to run some errands and on my way home i turned a corner and when i put my foot down on the gas pedal the car just went "Put-put Put-put" every time i pushed the pedal more than a 1/4 of the way down. i reach a stop sign and being i was in the middle of nowhere and no one was coming down the road for miles i braked slightly and went past the stop sign halfway through my turn the engine died and i coasted to the side of the road, i got out and checked the engine, i had coolant not a whole lot but enough, then i checked the oil and it as far as i could tell it was at the add line even though it had been fine a few days before,(there has been no indication of an oil leak).
I rechecked the coolant and it looked like there was more in there than there was a few minutes before but i couldn't be sure, i was able to get the car restarted and headed towards home (about 2 miles away).at this point i was able to get the car going at around 25-45mph on the next sharp corner i turned the engine died again so i restarted and kept going, it died once more right before i reached the driveway but i was able to coast the rest of the way, once i parked the car i turned the engine off and tried to restart it a minute later and it started again so i left it be and called someone to bring me some oil, when they got to me with the oil i put some in and and it would not start at all.
- I checked one of the spark plug wires and it is not getting any spark.
- The ground terminal on the battery seems to be stripped
- The battery / altenator / starter---- All read to be between 12.15 and 12.36 volts
- The head lights, instrument panel and such still turn on properly.
I'm at a loss here, it was just in the shop 20 days ago and now it isn't working again. I would prefer to not have to put it back in the shop, if it might be something i could repair from home.
Chevrolet - 1500 :: 1990 - Running Rough / Hesitating / Lurching And Not Accelerating Smoothly
My 1990 Chevy Silverado with 5.0 liter, 45k miles has started a problem that the guys in my diesel repair shop don't know what to do. Last week it started to run rough, hesitating and lurching and not accelerating smoothly. It idles fine, or pretty well, but just doesn't run smoothly with any kind of acceleration. I drive it back and forth to work just 1.5 miles during the week. I took it on vacation a week before, so it's not from lack of long trips, it ran fine.
A guy at my diesel repair shop put it on his Genesis scope and all it would code is the O2 sensor showed lean, but we could see it switching from rich to lean and so on. I thought vacuum leak, but couldn't find one. PCV valve is good. EGR valve is ok. I changed the fuel filter yesterday and thought it ran a little better, but now has gone back to the rough running. What I can do myself to diagnose this? I do have all the tools and shop.
Lumina :: 1990 3.1 - Idle Surge After It Warms Up
My 90 lumina euro 3.1 has idle surge after it warms up. fluctuates between 600 and 1200 rpm when in drive. When you first get on the throttle it wants to die. Once you get past that it runs smooth while driving. Ive also notice that it tries to "buck" when its at lower rpm and barely on the throttle while pulling.
I can't seem to find any vacuum leaks, has recient tuneup, had a egr code and that has been replaced. I've cleaned the throttle body also. Previous owner had intake gaskets replaced as well as fuel injectors, fuel rail, fuel pump.
