So I have read another post on this before and see that there is probably a misfire, either from a bad coil pack, wire or spark plug.

But the engine doesn't seem to be having a misfire (or it doesn't happen when idle).

Some background on this car, its a 2005 and the guy I bought it from had the car sitting for about one year. He had replaced the timing belt, head gasket and a couple of other things.

I have cleared the codes by unplugging the battery for 15 minutes and this car does throw the lights up again right away. I've also noticed that 3 of the 4 plug wires have been replaced with blue ngk wires, while the 4th looks original.

I just went out on my lunch hour and bought an obd2 reader, going to see what specific codes are coming up.

Was wondering if there is anything I am missing from this troubleshooting list. Thanks!
