Thanks Gary. I has had new wires and plugs recently. It's been doing this for months now and finally I found this site for help. I can't take it to a mechanic cause it doesn't happen all the time. I will try to clean the IAC Valve and go from there. I will tell you what I find. Thanks again. Tony.

The car has 140k on it and in good shape. Where is the IAC Valve? And what does it do? Thanks for your help.

On my 94 2.0l the idle will jump up to 2000 rpm for a second and them back down to 400 rpm and levels at 900. it does this on occasion and not every day. It shows no code and is driving (pardon the pun) me crazy. I have taken it to part stores and no codes. Has anybody experienced this problem? I don't want to replace a whole bunch of stuff if I don't have to. Thanks. Tony.

Hey thanks guys for the help. This will make it much easier. Off to work I go.

On my 1999 Legacy automatic 2.5l, the knock sensor maybe bad. I have bought one but cannot find it even with a serivce book. Does anyone know where it might be? Thanks for your help. Tony.
