Re: Engine idle jumping everywhere
Does it do that all the time or just when the engine is warm?
I've read a couple of things, best to do is to check MAF,air leaks, lambda sensor and also check the butterfly valve and throttle body (you can clean it as well).
I'm having the same problem and still didn't figure things out.
You can check gazza's page for more tips (see Idle saga). The link is in his signature.
