just tried starting it again, spark plugs didnt work

I had idle problems about a year ago. After taking it for a tune up(at the dealership) it still had the same rough idle.
My solution ended up being a fuel filter. I changed it out and the car was instantly back to it's old self.

I'm not a mechanic and don't even own a technical manual for my Celica so these answers might be completely off. Don't blame me if you try a repair based on one of my suggestions and it doesn't fix it . However I can offer you some idea of what to look for to help diagnose the fault.

As it sounds like your engine is hunting for idle there are three specific areas that need to be investigated:

It might indicate that there is a problem with the idle control system who's job is to provide extra air to the engine when started from cold to regulate the idle speed. I don't know the specifics of the system used in Celica's but there are normally several components involved. You'll need to check with a mechanic as to which system is in the Celica (unless anyone knows?) but it will most likely be either a servo driven or an air controlled system, both of which have moving parts that can become clogged.

It is also possible that there is a problem with the fuel\air mix. This may be due to a clogged fuel filter or the O2 sensor may have a problem. The O2 sensor operates at very high temperatures and I have heard that failure is quite common on high mileage Celicas. Without a properly funtioning sensor the fuel\air mix is wrong and can cause the engine to either run very rich or lean. This is not something you can readily diagnose, but a good indicator would be to smell the exaust gasses and see if there is a strong petrol smell.

Finally this can be caused by a problem with the Catalytic Convertor. If its not connected or is damaged then this can also cause the fault, as the gasses can't escape. An emissions test will confirm if it has a problem.

All in all I would suggest taking it to a Toyota dealer and getting it looked at.

where can i get nology wires, and how mcuh will they be , it turns out im gonna be needing new wires, rotor, cap, possibly new pulleys and belts, new air filter which i already ordered, and the fuel filter im trying to get in but is being a b!tch

[Negative]

You can get nology wires on nopi.com or quite a few other places. They're going to be expensive though. The NGK wires work really good and are only $41.00 on NGK.com.
As for the fuel filter - you really have to put some torque on the fittings to get them to seal right but don't bend the mounting flange.
After you do the stuff you mentioned your car is gonna run great. Don't forget to clean the injectors.

[slipgun]

Is there seriously any reason to get anything other then stock for a stock engine? Arnt stock wires cheaper then that? Or are wires as overpriced on cars as everything else

[Doge]

Don't get the nology wires Dirty. The extra "charge" is just a marketing ploy. Get the NGK wires...they are just as good if not better and alot cheaper. And don't think that I'm saying that cause I have the NGK's. I bought the Nologys and it just wasnt worth it. Having a ground on each plug wire is useless to us...but usefull to nology because they can charge and arm and a leg for them.

[Negative]

Agreed.

thanks doge

this is what its looking like right now . tonight im talking to my uncle who is a mechanic, we are going to do the fuel filter and hes checking out my belts and pulleys, turns out im also gettin weird virbation and sound coming from that. its a new timinig belt 10k miles so its not that. and the water pump and fuel pump are possible problems that need looking into.

if there is something wrong with the pulleys and belts and all that good stuff where a repair would be over 500 dollars im gonna start looking into another car. as much as i love my car its not a standard and its no v8. iv got my eyes on mustang gt. but we will see what happens. the mustang may own my car in a race but my car looks way better (even as a muscle car fan i have to admit that).

ok i just talked to a mechanic, he said most likely its sensors so i gotta bring it to a place and hook it up. besides the cold start issue he said its actully running perfectly. the egr valve is not the problem, it works fine. so ill be finding out soon.

o yea and to that post earlier about revving it up high to about 6k. i found out that is quite damaging to the engine from a cold start. there isnt enough time for the oil to move around and all that good stuff. so any one here with a simlier problem make sure u dont do , youl just be taking miles off the life of your engine

[spunky393]

we never said do it right when your engine is cold, that's just being a dumb***. Of course you should let it warm up a little bit, things like that is why peoples cars don't last, common brains.

[DamDirtyApes]

for some reasen its not doing it or not nearly close to doing it at all today. it might of been my uncle.. he took a hammer to the egr vavle becuase we thought it might have been stuck.....

o yea got the k&n in today..... me likes alot! sounds better at higher rpm and gives a lil teeny bit of power.
