AAMCO says its the PCM, they want 900 to replace it. I'm going to do it myself, it seems like an easy replacement, so long as I get a direct ECU replacement.

My question, and perhaps I need a new thread for this, is my car does not have the special PATS keys for the ignition, but it does have a weird second "key" that plugs in under the steering wheel, like a separate computer chip. Will this give me trouble?
