My "Check Engine" light comes on without exception any time I give the car full throttle. That is, whenever I floor it, no matter what the RPMs, the "Check Engine" light (usually cylinders 5-8, but sometimes 1-4) will illuminate for about 3-4 seconds. Ya know, I very rarely floor my car. So a while back I found it curious that the "Check Engine" light had come on sometimes when I would hit 7,000 RPMs. But since I don't go up there that often, and since I don't floor it that often, I thought it was just a freak thing. But now I realized after flooring it today and playing around that it does it consistently. If I were to guess, chances are 95%-5% in favor of this being a false alarm--a silly loose connection or something. Any thoughts? I've read about people "pulling" ECU codes from 348s--that is, interpreting what the "Check Engine" light is trying to say. I have in my possession the chart from the technical manual that translates the codes, but how do I "pull" the code?
