Lumina :: 1990 3.1 - Idle Surge After It Warms Up
Feb 2, 2011
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.

My 1994 Chevy Lumina drives great when its in motion but when it warms up it will stall when your at a stop light. It does great at a quick stop, like a short red light or a stop sign but when I am sitting at a long red light it just stalls. It will start right back up but this is annoying. Recently the car radiator was replaced, so the car over heated. What could the problem be?

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.

I have a 1990 chevy lumina 2.5 L 4 cyl. 100,000 miles....The car recently started chugging while in drive and will not accelerate correctly, when I do get it to 55 mph there's still chugging, Ive replaced the fuel filter, spark plug and wires, fuel system clean, new battery, there is a inch crack in the exhaust manifold on the front of the engine, not sure if that would make me lose power to accelerate, the car idles fine, but chugs when put in drive, and will occasionally die when put in reverse....

I have a 1990 3.1L, multiport fuel injection (NOT sequential FI), which runs very well most of the time. However, when I cold start it runs rough (misfire) for about 1 minute (no throttle) or until acclerated. The is no misfire when running normal, but it might be running a little rough when stopped at a traffic light (in Drive, foot on brake).
I put new plugs and wires on, but it did not affect this problem.
I am not using coolant, or oil, the plugs that were removed were somewhat worn, enough that I expected to notice a difference after they were changed.
I have not yet (1) cleaned the MAF, (2) checked carefully for vacuum leaks, (3) checked for leaking injectors.
Since this is a 1990, OBDI, I can't say which cylinder is misfiring or how the fuel trims look etc.

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.

Car has 252k miles runs ruff after engine warms up, looses power, if I give more gas, car will sputter, but rev up to 5k engine smoothes out. This situation constantly comes and goes.

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.

Recently when I start my car, it starts fine when it's cold because it will idle high until it warms up, but if I start it while it's warm the rpms drop to about 500 barely idlling and if I tap the gas a couple of times the problem goes away and it idles normally at about 700.
I recently also replaced the o-ring on the distributor because it was leaking oil. I reset the timing twice. It is hard to get an accurate reading in the dark, looking at a little timing mark 3 feet away, but I am sure it is at 10 BTDC.
New wires, new thermostat, air filter could be a little dirty, other than that, I am thinking it might be an oily sensor or something else?

We have a 1996 GMC Sierra 1500 Turbo Diesel and since yesterday, it's had a problem... When it warms up, it runs really rough and misses at idle. While it is doing this, white smoke spills from the exhaust. When we rev it to about 2000 rpm it runs smoothly. Sometimes at idle it misses bad enough to stall. Some say it could be the IP, EGR or injectors?

2001 Grand am 2.4. Runs fine when the engine is cold but when it warms up the idle is rough. When throttle is added from idle, RPM's drop, it hesitates, then either stalls or goes. Car runs just fine when there is a load on the engine (highway speeds). Sometimes it will even stall coming onto off ramps off the freeway. It intermittently shifts hard. SES light is on p0108. Have replaced the MAP sensor and checked for vacuum leaks, still have the light and the same problems.

My 1992 Toyota, Celica had developed a really weird idle surge. The idle surges between 500 to 750 rpm. The surge goes away with the AC on and it idles steady at 900 Rpm. It also has a slight off idle bog that may just be another symptom of the weird idle.
I did the diagnostic test today and it doesn't flash any codes. I pulled the EGR valve off and cleaned the gunk out of it and it didn't make any difference. I tried to check the timing and it idles so bad the timing bounces 7-10 degrees with the surge. When I did the jumper to check the timing it would kill the engine. The plugs and wires are new with in a couple thousand miles. It runs fine above idle and pulls to redline easily in the lower gears.
Yesterday when I was messing with it I had the car running with the air boot from the air cleaner to throttle body off. I sprayed carb cleaner into throttle body and it seems to clear up a little bit. Then it went back to surging again.
I tried to pull the TPS off yesterday and of course the bottom screw stripped out. Now I will have to pull the throttle body off to get the screw out. I wish it would throw a code so I could have it give me a clue.

I have a '99 Dakota 4 cylinder. Starts fine but as it warms up or if you gas it the idle stays high. The more you run it the higher it goes. Have replaced MAP senser, throttle position and air bypass with no effect.( map and high tps voltage only codes shown ) Vacuum problem?

When I drive the idle surges up and down and stalls when i slow down.

have a 2000 Honda CR-V with a B20Z2 engine and automatic tranny. This Honda has an idle surge that just won't quit!! (surge= rpms rise and fall, repeat) It's really driving me nuts and I need this car to drive for school next week! So far, I've:
-cleaned throttle body
-replaced spark plug wires (plugs are fairly new), distributor rotor, and distributor cap
-bleed coolant
-ECU relearn idle
-adjusted intake and exhaust valves (tight exhaust valves are incredibly common on my engine)
-cleaned out Idle Air Control Valve with Simple Green
-performed vacuum test (with propane, not carb cleaner since it works the same)
-performed compression test (every cylinder checked out)
-replaced throttle body gasket
I've had Check Engine Light misfire codes for a while now, but they pretty much disappeared after the valve job. All that's left is an Idle Air Control System code (P0505). I'm am completely stumped at what to do now. What's more is that white smoke has started pouring out of the tailpipe and it doesn't smell like coolant. At first I thought it was the oil in the cylinders from the compression test, but now I'm not sure. It doesn't really smell like oil or coolant, but it smells like something is burning....

Recently replaced crank p.S. that a dodgy mechanic installed app 5 myths ago seems he used after market Chinese shit instead of ome gear well one thing leads to another as all jeepers know with highway speed engine missing when engine warms up l found that instead of running power cable from sensor above the trans fluid tube , in his wisdom ran under said tube causing a short to the computer not realy the best for them , now l have issues with idle ,02 , tps, possible computer.

Since we bought this car, it has had an issue where, after it warms up, it begins making a noise which I've seen described as "moosing" on the internet. In addition to the sound, the idle will decrease and will sometimes kill the engine.
I've seen this attributed to the IAC, and so I replaced it (twice). I have tested the IAC connections as well, and all is good. I have even run the car without the IAC plugged in, to try to reset the computer, to no avail. I feel like I have eliminated the IAC from being the problem (but maybe not.)
I have replaced the PCV valve.
I have replaced the water temp sensor and the thermostat (someone suggested this might affect the computer and rpms...)
I have cleaned the MAF and tested it per the Chilton's manual. (tested fine)
I suspect that because of the idle and the engine seeming to be choking out when it dies, that there is a vacuum issue somewhere. I just don't know where to start with this.

1997 Ford Econoline HD Club Wagon E350 2wd 250k 6.8l V-10 Factory front and rear air, rear evap is there but all other components were removed from previous owner to use as a work van.
Air works great other than at idle it warms up some, not a real big issue at the moment, and also has a small vac leak somewhere as under heavy throttle or towing any bog will change vents to defrost and floor. not a big deal at the moment.
My issue right now is I was driving yesterday down the interstate air on full blast freezing me real good (awesome at speed on these 100 degree days in NC) and all of a sudden ambient air, no more awesomeness.
I pulled over to take a quick look but was way too hot to sit on the side of the interstate and look further, got the ole girl home and looked at it today.
Compressor kicks on as it should, but all the lines stay the same no condensation, blend door is moving to adjust from any vents the control tells it to.
My question is if it was low on freon the compressor wouldnt kick on at all, and if its up and cycling correctly why aren't the lines becoming cold? the temp door is also working as with the van warm the air will blow hot then when i switch it back to cold it gets cool just not cold, temp of air around blower.

I have a 97 Lumina sedan. When moderately accelerating between 50-60 on a slight incline, the car will sometimes start to "jolt" a little repeatedly. It continues to do it if I hold the pedal steady, but if the incline goes away or I press the gas pedal to accelerate harder the jolting will stop as abruptly as it started. The magic number seems to be around 55mph, never outside that range. I can reproduce it on certain interchange ramps or hills, but only in overdrive. Regular drive gear doesn't do it but the engine is at a much higher RPM. If I accelerate harder than I usually do it also doesn't seem to occur.
At first I thought it was just the same RPM loss issue at speed in a low cruising RPM, something that happens infrequently at idle. But now I'm worried the specificity might indicate a transmission problem. Car only has 87K miles on it for its age though.

My truck has been having idle surge, low engine power, says stable tracks is off, computer said TPS pedal sensor. I replaced it. Within 3-4 days my truck does the same thing. I turn it off and eventually my truck runs fine with the exception of my engine light is on truck runs good. I put the computer on it again while the truck running bad and it continues to say it is the TPS sensor.
