Celica Forums General Discussion Exterior Rough Idle? Do this!

I've had a rough idle for some time now, it goes from 800-1200 rpm and hesitates when you press the gas.

Bought some choke/throttle body cleaner, took off the air hose, cleaned it out with a quick spray, made sure to spray into the IAP (or something like that) area, the little box on the bottle on the hole where air goes into during idle.

Hesitation gone. Only $3, go do it if you have a lot of miles.

I didn't even realize there was a guide for this

Still, it's something you can do to solve the rough idle problem. I've had no luck with the idle problem, until today

this doesn't always solve the idle problems but it can in some cases. you have to remember there could be issues with the spark plugs, fuel injectors, o2 sensor, iac valve or maf sensor (to name a few). but, it's doesn't hurt to try.

for $3, I think it's the best bet
