3rd & 4th Generation (1992–1996 & 1997–2001)Toyota Camry Discussion for years: 1992-1996 & 1997-2001
Topics of discussion range from fuel economy, safety, modifications, performance all involving America's favorite family car, the Toyota Camry.
So recently the car has been having trouble starting up when cold it cranks but doesnt start the rpm rises to about maybe 100 or so and really struggles to start but wont start. The only way i get it to start is to give it gas then it starts an runs like a champ also when the cars warm it does not have the problem yet... does any one know what im dealing with here. I had a similar problem but it was the gunk in the TB and i had to HOLD the gas to keep it running i had an air induction cleaning about 4K miles ago an its been fine until now.
IIRC, the 5sfe doesn't have a cold start injector. The 3vzfe does. A clogged/stuck IAC valve is usually the cause of cold start problems. I had the same issue with my 96 5sfe. I removed, thoroughly cleaned, and reinstalled the IAC valve. After I did that, no more cold start problems.

An air induction cleaning doesn't get to that? basically the throttle body was sprayed with something like seafoam 4k miles ago down into that hole. is there a diy for that at all? I know its complicated but if i had something to go by i could deff do it
My IAC valve was really gummed up with oily carbon deposits, not even half a can of seafoam helped. I tried every over the counter solvent I could think of, but none helped. Only scrubbing, and carefully scraping the inside of the IAC got enough of the carbon out to properly free up the valve.
You have to remove the throttle body to access the 4 screws that attach the IAC valve to the TB. Then you have to remove the hoses attached to the IAC valve. After you have the IAC valve out, clean with a small bottle brush, and some seafoam or similar solvent. Even rubbing alcohol, and cotton swabs will work for this job.

ok thanks man i honestly hope the iac is the root of the problem and cleaning work's so i don't have to keep troubleshooting like fenixus and his fuel trims lol. I hear you have to lube it up also (haha) after your done cleaning it is that true? Ill keep lookin for a diy because i don't really feel confident removing the TB without knowing what im doing
No lube, that will just quickly attract more carbon and dirt. I didn't put any lubricant in the IAC before I reinstalled it. It's been about 5 months since I cleaned it, and haven't had a problem since. Every morning when I start it, the engine jumps to 1000 RPM, then slowly settles down to about 750 RPM as it warms up.

damn that sounds healthy mine jumps to probably 1700 or so then quickly falls down to 1200 till warm but now it wont jump at all unless i give it gas lol if anyone has a thread or website where it shows how to take the throttle body off im sure i can figure the rest out I've been looking for a while now and cant really find anything helpful
Also, your car does not have a cold start injector nor a cold start time switch. The generation 2 Camry was the last generation to use that setup. Your car's cold start fuel mixture is controled mainly be the engine coolant temperature sensor and the main computer.

In the link I posted, file eg1.pdf deals with the 5sfe. Starting at page 45, it shows how to remove the TB.
