I changed my spark plugs and wires over the weekend because my car has been running a little rough lately. I found out that was mainly due to a spark plug wire that was barely attatched and my TPS was sitting at .50 volts at idle. Seems to be much better now.
Anyways, I noticed the plugs for 1-4 were all very black like it's running way too rich. But, the plugs for 5-8 are all dark but not nearly as black as the other plugs. I've been having a wierd pinging noise that to me sounds like it's only coming from the drivers side(5-8) of the engine. So what would cause one side of the engine to run way rich and the other side to be not so rich? My first thought is the O2 sensors, what do you guys think?
