Rough Idle, Varies between 650 and 900rpm. Options

[dudeofchaos]

My idle varies between 650 and 900 rpm and is a bit rough (The steering wheel is quite shaky), but as soon as I give it some gas (Just a LITTLE, around 950-1000rpm or more) it becomes a lot smoother and the steering wheel stops shaking.

I was wondering if changing the fuel filter and reseting the ECU could solve the problem?
Thanks!

Check your plugs, and clean/replace them if needed. How old is your iginition system?Also your timing might be screwed up.

My plugs are brand new. I changed them a couple of months ago, it was still hapenning when I just replaced them.
Maybe I should change my wiring set.

You should be able to adjust the idle speed via a small screw on the TB. I read that in my Haynes repair manual.

What does ''TB'' stand for? Throttle Body I guess?

you could try that. it works sometimes.

you could also try to clean the throttle by spraying carb cleaner or something similar.

Yeah, I should clean it. Is it hard to do?

nope! you just remove the intake hose or pipe. then with the engine running you spray the card cleaner and at the same time pull the acellerator cable to about 3000 rpm.

but if you really want it real clean, you have to take out many parts. and that is hard to do. you could just do this when there are other things you need to do like replacing valve cover gasket, etc.
