Celica :: 1987 GT Won't Idle At Lower RPMs
Feb 2, 2015
I have a 1987 Convertible Celica GT, with Manual Transmission. The car will not idle at lower RPM. I had someone look at it, and they have it where it will idle at 2000 RPM, but anything lower than that, and the engine will die when not giving it gas.
The engine accelerates great and runs great at any speed, but if you push in the clutch without giving it gas, it will die, unless the idle speed is cranked up like it is now. What this might be?

I was driving home from campus yesterday, and as I approached about 50mph, the Celica suddenly revved into higher RPMs, all the while slowing down. I pushed the gas pedal, which only worsened the problem. I was able to limp the car home. About an hour later, I tested the car again, and the problem remains: Accelerate to about 35-50, then get high RPMs while the car slows down and jumps forward.
I suspect a transmission problem, accentuated by a loose wheel bearing that I haven't been able to afford to get fixed yet. My Celica is an automatic, with about 213000 miles on it.

I got a 87 Toyota Celica 1600 GT, with a TVIS 4A-GE engine in.
My problem: when i just start the engine cold, it revs to 2500 RPM, and stays there for 1-2 minuttes and then falling to about 1500 RPM, and when the engine is completely warm my idle is about 1000 RPM.
first i think that 2500 RPM cold is a bit to much, and i dont know what to do with it. but my biggest problem is when the engine is fully warmed up, and i rev it to lets say 3000 RPM and then lets the gas of, the engine falls to about 500 RPM sometimes it stalls but if it not stalls then it would slowly gain some RPM and then it goes up to 1000 RPM again.
How can i prevent the engine falling that much when i let the gas off? it's quite annoying when i drive the car and comes to a stop it sometimes stall.

I have done everything I can think of to this car. New; plugs, wires, distributor, battery, fuel pump, fuel filter, relay, and electrical lines to fuel pump. The timing belt is fine. The car has a rough idle and when I am stopped the RPM's drop below normal. Now it won't start. What can I try now?

Hot or cold car always starts,Idles perfect , then RPM drops, Idles rough and stalls. Econometer moves to Red area.car will easily restart and drives well,it also idles well. Once engine is shut down, even for a short while, It does the same thing again. Car is used for short trips. Ambient Temperature 80 degrees. Once running car is perfect at all speeds and idles smoothly. Hero 1987 MB 560 sel ....

So I just drove my 85 to san francisco and back to Los Angles this weekend to visit my girlfriend and i had high oil pressure all the way until i blew my valve cover gasket.
So i fixed it finally today and it ran fine for a couple blocks and then my rpms shot up to about 3000 rpm and wont come down at idle speed and the car wants to keep going while in drive.
Its a 2.4l 22re EFI

I just got a 87 celica for $500. Anyway it runs at 2000 rpm's for an idle, could a valve adjustment be a possible problem? Also where is the best place to find some performance parts for this thing? Would like cams, headers, pistons......?

Car misses horrible at times at idle and lower RPM's, shakes the whole car. MPG around 32. Runs better when car is fully warmed up. PO171 and PO 300, 301 and 304 codes come up.
Here's what I've done so far to try to correct the problem:
Cleaned mass air flow sensor. No change.
Replaced mass air flow sensor. No change.
Replaced plugs and ignitors (coils). No change.
Replaced PCV valve. No change.
Replaced upstream O2 sensor. Same codes come up but MPG increased to 37.
Replaced throttle body. No change.
Car does not miss when accelerating hard. Sometimes runs perfect at idle and lower rpm's, but mpg is way low as it used to be in the 50's or higher. Car idles perfect in neutral. Always runs perfect the first 3-4 seconds when you first start it, then starts shaking. If I put my finger in the throttle body when it's running poorly, apparently disrupting the air flow a bit, the idle smooths to perfect.
I have an extra computer, although I don't know if you have to program the key for it to work. I don't suspect this is the problem anyway. I haven't changed the fuel injectors. I can't hear a vacuum leak.

Yesterday my mom used my car and the battery light came on while driving, but she didn't really care about it and was driving the whole time on the battery. When she came back home the car was barely even alive I couldn't even start it. I replaced the alternator (duralast from auto zone) and the serpentine belt, but now I have a very rough idle and the rpm's are lower than usual. They are 1500 instead of 1750. Is this normal and eventually it'll go away or did I mess something up?

I have a 100% stock 2004 Celica GT ~125,000 miles. Over the last few months I have been getting a rough idle and stumble at low rpms. The other day the car would not restart after sitting for about 20 minutes. Only recently has it actually thrown a DTC. The error codes were for misfires (P0300, P0301,P0302,P0303, P0304). I don’t get a code every time but the problem seems to be more noticeable if the car has been ran for a while, sits for 20-30 minutes while in a store and then when I try to start it when I come out of the store is when the problem most often occurs. When it restarts it will stumble at low RPM and if I hit the gas it has little response and misses badly. I have never used a scanner until now. I am using a Autel MS509 scanner and I am not sure it is giving me the correct diagnostic numbers for the live data. I think the DTC are correct but the live data is questionable.
Here is what I have done so far.
- Cleaned IAC valve (completely removed and cleaned)
- Searched for vacuum leaks using carb cleaner
- Cleaned MAF sensor
- Replaced all 4 injectors
- Replaced upstream and downstream O2 sensors
- Replaced Coolant Temp Sensor
- Ensured cam tensioner is providing adequate pressure to the cam chain
- Tried 2 sets of new Iridium NGK plugs and a new set of Bosch Copper plugs
- Moved coil packs around
- New air filter
- New fuel filter
- SeaFoam through intake and gas tank. I have not mixed in the oil.
- Compression Test (1=190,2=190,3=160,4=178)
Things I have not done.
- Taken it to the stealership
- Fuel pressure test
- Valve Clearance
I am concerned about the compression test because according to the service manual it should be around 218. I was using a Harbor Freight compression tester and I am not 100% sure I had a good seal with the tester.

I have a 2004 SD with 5.4 that is running pretty rough both at idle and driving. Truck shakes a lot at lower rpms. I have a scan tool and had a misfire on cylinder 4 so I replaced the coil and the plug. Also replaced the idle air control valve. Plan on replacing O2 B1 S2. (One of my codes) even after replacing the coil and plug I'm still getting misfire detected from cylinder 4??? Other codes I had were misfire detected on he first 1000 revolutions. That hasn't come back though.

My 1987 Toyota Celica ST will not seem to turn over. When it has the push button addition that takes the power from the battery straight to the seloniod it works. But when i set the starter back up to the ignition switch and set it up factory style it will not spin over. it sends the 12 volts needed to start it but yet will not turn it over.

1987 Toyota Celica GTS 2.0 manual Transmission The Problem ... The power cable to alternator sparked on the side of the engine when I was connecting it. I did not think the battery cable was connected at the time but it was.. Now I have NO SPARK I have changed all the fuses at the battery could not find any that were blown but still changed them and checked all the fuses under kick panels none were blown. What should I look for now?

Last week the rad cooling fan stopped working. The fan itself is fine. It spins when connected directly to the batt. Relay tested good, and fuse isn't blown. I unplugged the temp. switch connector, and grounded it to the batt. to test the circuit, and nothing. Switched on the A/C, and both fans spin. So, where else should I look for the problem?

I have an '87 Celica and it takes a good 10 seconds of cranking to start. After being parked only 24 hours, it's the same thing. It won't even give a hint of a kick until about the 8 second mark. Then it'll give a couple of sputters and eventually fire right up. Is this the fuel pressure regulator that's the problem? Is it not keeping the fuel at the rail pressurized properly when sitting? It's just annoying having to sit there cranking for so long to get going. I would think if it was the pump, it would give me problems when running.

My 1987 toyota celica brake pedal is going to the floor when I apply the brakes but not all the time,i checked the pads and shoes they are still good i also bled the brakes, I am thinking it is the master cylinder or maybe the master cylinder needs to be bled.

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 am needing to replace a bent drivers side lower control arm, but it looks to me the 'front most' control arm to frame bolt is situated right next to the auto transmission! How can I snake this bolt out? Do I really have to raise the engine/tran up to clear this bolt on the control arm?
