6G Celicas Forums

The timing belt cover has been warped and the gasket between the timing cover and the engine. there could be some dust/dirt build-up... but I dont think it's that. I think it's electrical. I took off my distributor cap and saw a small amount of carbon scoring around the inside of the cap. where should i go from here? I know there has to be a good amount of certified mechanics on this forum so please help me out! thanks

Right now I have unhooked the exhaust directly from the bottom of the catalytic converter just for the sound.... kinda like open header sort of thing. What happened is one day my engine was running fine and then the next day I am experiencing a high Idle ~1200 rpm and the fact that it won't rev past 4100rpm. I replaced a rear motor mount which made me happy but I'm not so sure that I want to put more money in this celica... 6gc guys: does this sound fixable? what should i check (using a multimeter)? Thanks in advance!

wow thanks for all that useful information!

ok guys... I changed the oil, changed the transaxle fluid, changed the spark plugs, changed the plug wires, and gutted my catalytic converter. Still no change. I tried hooking it up to a 2 bar map sensor off of a all trac and it ran fine but still would not rev above 4100 rpm. Now this brings me to the conclusion that it must be fuel delivery system related.
I checked my injectors one by one and the first injector felt a bit loose like the O ring might be weared so i ordered a new O ring set. Another thing I'm going to go ahead and change is the fuel filter and pcv valve. I know that my PCV valve has 162000 miles on it so I'm going to try all of these things and if I have no avail then I am sorry but I would be forced to sell off the celica and leave the 6GC club which I don't wanna do. Does all this **** I'm doing sound like im on the right track or am I pouring money down the drain?

Also, unplugged the O2 Sensor with no noticable difference.

I have quite a few problems. First of all, I'm 2000 miles over an oil change, Let's just put that on the table. My problems include:

*rev limiting at 4200 RPM, with MAP unhooked reached 6200rpm but had definite knocks in the pistons (REAL bad timing)
*idle shakes like you've never seen before. I mean I'm talkin about like the vibrating beds at the motels that shake vibrate.
*I have been gettting EGR CEL engine codes but they've gone away after some re-routing

Help me with my celica. I know for a fact that all four mounts need to be replaced (162,000m) that would probably eliminate the shaking. I did also notice that my #1 fuel injector seemed to fit very "loosely". Could a faulty injector be the problem? Help me out 6gC Buds

So you think it's my EGR system?

I'm looking at a few things that might be affecting this:
fuel pump
fuel filter
MAP sensor


ORRRR could EGR just be hooked up wrong (ex. wrong vac lines routed) because I think my cousin was messin with my manifold the other day.

yeah but still my redline is 6000k and it used to rev that high. Now it doesn't. I disconnected the Vacuum sensor relay and gave it gas to keep it from boggin off... i revved it and it did go to 6000k but it was useing WAY too much fuel. I'm sure all of this has to to with the fuel injection but I dont know exactly what.... HELP ME OUT GUYS

Well thanks for the help guys I guess it's off to the Toyota Stealership.

I thought us yota monsters were supposed to stick together?
Anyway I guess I'm going to try to figure it out myself.

Only thing about it is the MAP sensor.... I unplugged it and it was able to rev up to redline but not without knocking. I guess I'll go to the junk yard and look for something to replace it with. Doesn't seem like I can find much help here.

It wont go above 5400 RPM even in neutral. When i take it to 5400K it sounds like it is absolutely wide open. It wont accelerate past 5400k but it will actually start to decelerate (while i have the pedal floored!)

Jees, I never seen anything like this before help me out guys

Already did, EGR system malfunction I think?

lights on for 7 times then pauses then lights 1 more time.

1994 Celica GT
I have had a check engine light on for about a week now but haven't checked it yet. Last night I was driving my car and it was fine. Today I was driving my car and it seems like it has more power it just won't rev past 5000k. When it does make it to 5000K it sounds REAL loud and the sound is coming from my short ram intake. After holding it at 5000k for a few seconds then it bogs down and starts dropping. I was too afraid to push it any harder so I pulled it over and now I need some help from you guys.....

WHATS WRONG WITH MY CELI
