Started two weeks ago: upon a high RPM, I get short sputtering loss of power. I then floor it, engine gears down, and I take off fine. Particularly bad fits occur going uphill. Thought at first that it was a transmission problem. Engine light came on two days ago.

Went to autozone, their computer reader told me it was a cylinder 3 misfire.

If that is correct, I cannot express my relief with mere words.

The question: do the symptoms match?

yeah, the syptoms match but i don't know why you're relieved. a misfire can be caused by anything from something simple like a bad plug/plug wire, carbon build up etc., or something major like a blown head gasket, cracked head, something broken in the valvetrain, etc.

have it diagnosed at a mechanic, as bigblueram said it could be something simple or a major fix

could also be electrical which is yet another headache.

betting on plug/HTL over here, be sure to keep us posted

im having a similar issue with my '99 firebird. went to my cousin (who is a mechanic) and he said with these cars, the plugs are supposed to be replaced at 100k miles, but most the time they will go before that. Also they have a history of the plug wires going bad before the plug even goes bad. sounds like a similar situation

Taking it in this morning. Will know tonight. I watched it roll over to 100k on the way home from work yesterday.

^ yep. 9 years old and never a checkup. That was indeed the problem.

Bad coil on cyl 3. Also for the hell of it got six new iridium plugs and new wires. She flies again.

there is no individual coil for cylinder 3.
