Celica :: Low RPM Idle At Startup When Car Warms Up
Dec 9, 2008
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?

So my truck a stock 2000 7.3 started smoking when I would start it up in the morning... figured it was a glow plug issue. Checked the relay it was good, checked the glow plugs found 2 were bad replaced them.
Thought I was done, well I started it up and took it for a drive. still smoked... thought no big deal I know some oil leaked into the cylinders doing the glow plugs.
Then it started rattling like a lift went out, no more smoke though because the truck was warm... shut it off at my buddies. Limped it "it actually still drives ok" 5 miles home.
From my research it sounds like an injector. I have tried a buzz test and they all sound the same.

My brother was the original owner then passed it on to me. I then passed it on to my younger cousin about two years ago. The car is completely stock and has never been modified. Everything is OEM.Just a couple of weeks ago I was called by my cousin saying the car broke down on her .The problem is that we took it to a few mechanic shops but they still haven't fixed it ...
Problem with car: When pressing on the gas, the idle drops and then the car dies (a scary event that happened to us and on a main road). I do not wish to bring it to another fail mechanic shop.What the shops did: changed all fluids, distributor cap and plugs, new spark plugs, and replaced air intake piping with oem piping.

I have a vibration that rattles the cab of the car during start up. But if you get out, lift the hood and listen, you cant hear anything. Its only in the cab where you can even tell there's something not right. The motor runs great and seems very smooth to the touch and visually.
The vibration does seem to go down as the car warms up..... Somewhat....You can hear the vibration when driving and go down through slight dips in the road. Kinda like hitting the rumble strips on the side of the hwy.When I release the clutch and under power the vibrations go away. Under deceleration the vibrations are loud.After weeks of research, both TN and the web, I have done all this so far.
Changed Plugs, wires, cap. All four engine mounts were taken out, inspected, and 3 of the 4 were replaced from a donor car. All 4 looked good anyways....
Swapped harmonic balancer/pully from a donor car.
Compression check. 196 200 200 208
Cleaned IAC valve.
Pulled off exhaust manifold and verified CAT isnt broken.
Inspected exhaust from front to back and cant find anything.
Replace timing belt, tensioner bearing and idler bearing while I was in there.
Took both fan belts off and ran car to see if maybe power steering or AC, but car still rattled even though they weren't turning.
Did head gasket while building this car up because it was leaking oil from the front return tube area.

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?

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.

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.

So I have a 91 Celica 1.6L and the problem Im having is that it does not want to turn on with just the key. If I spray Starting Fluid into the throttle body then turn the key, it'll turn on and stay on and even drive without any hesitation. I did the diagnosis test with the jumper wire and the codes I got were :
Code 22: Water Temperature Sensor Circuit Fault (New Sensor)
Code24: Intake air temperature signal fault
Code 32: Air flow meter circuit or vacuum sensor signal fault
I never owned a toyota prior to this so I don't know where to start looking for a solution.

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?

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.

When I start the engine it works fine while the motor is cold (idle normal all smooth). When the engine the temperature reach normal operating range the car loose power and idle drops to 350-500 rpm and if i am driving I can not go over 40mi/h. I drive a 2008 Sta Fe now with 96000 KM (~~60000 miles). A month ago the engine start shaking severely and knocking noise (like some spark plugs where not working), from this to now:
Changed all sparks plugs
Changed all ignition coils
Now this situation looks more related to temperature of the engine.

My 98 Maxima won't idle without dying, it sputters when you accelerate, and it tries to die while coasting. I've changed two O2 sensors (AutoZone gave me the code for bank 1 sensor 1 & 2) changed spark plugs, tried fuel injector cleaner, oil change, and cleaned MAF sensor & checked the wiring. It;s still spitting out the black exhaust. Although after changing the O2 sensors it quit for about a day or two but started again (I'm guessing the other sensors need to be changed to) But the main problem is once it warms up, it really runs like crap, and is a major gas hog. I'm getting about 12 Mpg.

!995 honda accord, 5 speed. Idle is fine until the engine warms up, then fluctuates between 1500 to 2500 rpms. The idle control valve was cleaned- no change. Valve was also replaced -also with no change. Put old valve back on. Computer was disconnected after cleaning and also after each valve change.Would the next step be to remove and clean the fast idle thermo sensor? Also how do you check the coolant lines coming in. Anything else I would need to check, clean or replace.

I bought this from my brother in better than mint condition. Always maintained. Its generating a cyl #2 misfire code.
It starts and runs like new when cold, but when it warms up, it idles rough, and generates the code. after 1500 rpm it smooths right out and runs fine.
He had it to the dealer just before I bought it and they told him needed a new engine.
I am thinking bad injector, since what seems to be happening is, when cold it gets more fuel, or when u rev it gets more fuel, but at an idle and warm, it doesn't seem to be getting enough maybe. And I see from the maintenance records, a couple of other injectors have been replaced as well.
I think the dealer got tired of replacing injectors under warranty and tried to milk him for a new engine.

04 f250 364000 miles 06 6.0. New fan clutch. Ac didn't work when I put the engine in found out the fan clutch was bad so I replaced it. Now it doesn't turn at idle until the engine warms up even if I have the ac on. In the mornings it comes on and keep the temp at 190. In the after noon when if finally comes on truck runs at 210 to 190. Fss 530 when on at 210 at idle. And 800 at 1200 rpm what is going on.

Could a bad vsv be affecting my idle speed? I'm wanting to adjust idle as per the maintenance schedule and i don't know if i should wait until after i replace what appears to be a bad VSV. Also, where on the top part of the wiring harness i can connect an ohmmeter so it runs to the VSV so I don't have to get back in that tight area?

I have a 1995 celica gt at times the car was hard to start it would start idle really low then cut off this went on for about 1 month. The other day I was driving it and stopped at a light the car cut off and wouldn't restart. I originally thought it was a fuel pump so I took off the fuel line going to the fuel filter and attempted to start car fuel came out so I knew the fuel pump was working.
I then pull out 1 spark plug put it in the end of the spark plug wire and held it against the block while someelse cranked the car no spark was observed. I then marked the distributor and removed it. I looked at the rotor and it was really worn also the ignition coil had a crack on the side of it. I removed it and went to auto zone and found a replacement for $42.00 they sell two different type one for the 1.8 engine and for the 2.2 engine so know which engine type you have. I put every thing back and the car ran fine. However I would like to bring up the rpms a little they do seem low but I attempting to find out what how to do that.

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.

Just acquired a 1990 celica gt at a steal lol and needing some troubleshooting answers. tonight was the first night we really had drove it, but my husband drove it to work which is an hour away and he noticed that when he comes to a stop the oil pressure light comes on. as soon as he starts to go again it goes off. the engine does not make any noises other than the typical 2200 lifter chatter and it does not leak oil.
We plan on doing an oil change so we are not sure if that could just be the issue or if it's something else. we had this issue with a dodge ram we had and it ended up being the oil pressure sending unit. he took the one off the car and it did need some tightening up but however when he put it back on the issue was still there.
We do not believe it's any low compression as the car cranks fine and normal with no rising of the cranking as you would get for a cylinder with low compression. we aren't really sure about the bearings because well that's not one of those things easily tested but the engine doesn't make a noise which I know at times you won't have one.
