Car will not stay on after starting? - Toyota Nation Forum : Toyota Car and Truck Forums

I have a 99 v6 manual transmission solara. After I start my car it suddenly turns off? THis is the first time this happened. It hasn't been tuned up for a while. I know people are going to shoot random answers of what it could be but I'm more looking for answers that come from experience. Has this happened to anyone before? Any help will be gladly appreciated! THANKS!!

Sounds like the Idle Air Control Valve, but if you want more accurate answers, give more details!

Mileage? Outside temp when it happens? How old is the fuel filter, spark plugs? Last throttle body and IACV cleaning? Have you tried seafoam or fuel injector cleaner? Any Check Engine codes?

about 140,xxx miles.Outside temps are about 75 F degrees. I haven't done any of those things that you mentioned pmesfun and there has been an engine check light for a while. Its my sister's car, so i'm pretty sure she hasn't done any of those tune ups other than oil changes. I'll clean up the IACV and do the seafoam + spark plugs. It would be safe to clean the IACV with brake cleaner or no? Thanks for the reply! Has anyone else had this problem?

Sure sounds like the IACV, its a common problem for these cars. Use only throttle body cleaner to spray down in the IACV port hole and clean the throttle body as well. Let the cleaner soak in the IACV for 10 minutes. You will have to press the throttle pedal as it will be difficult to start and you should notice white smoke(cleaner and carbon burning off.) There is a procedure to change the spark plugs without removing the intake plenum, Spark Plug Change 1MZFE Engine - The Easy Way. FYI use on Denso/NGK oem spark plugs and posting in the 3rd and 4th gen Camry forum will get more views. Also seafoam before you change the plugs.

Also get the CEL code scanned and post up the code. Auto part stores do it for free.
