So far I have only noticed the problem in first gear (it’s a manua transmission), only when the engine is cold, and under heavy acceleration, but it has happened a couple of times recently. There are no engine lights coming on. The car has almost 90K miles, but I just purchased it recently.
It looks like 2 of the coil packs have been replaced, because they look newer than the other 2. I could try changing out the spark plugs, but other than that I would like to be able to troubleshoot the car to avoid replacing parts that I don’t need. I can take it to a mechanic, but I would like to learn how to do more things myself, especially since I’m going to be driving older cars (for financial reasons). lol
