I recently got a really good deal on a 95 maxima for my wife. It has 101000 miles on it and seems to have been taken care of pretty well. We have had it for about 6 mo now and i am having a persistant problem. The car seems to stumble on acceleration, and has a small miss at driving speed. When i popped the hood to check things out, i noticed that one or more of the coils are arcing to the intake. Could this possibly be the plug wires, or do i need to replace these coils? The way it is running is causing the ECU to throw 02 codes, and knock sensor codes. I just wanted to ask before i went and spent a ton of money on parts.
Also, Recently, the rear main seal has started to leak. It leaves about a 3 inch puddle under the car every time we drive it. Could this be caused by the uneven stresses on the motor due to the missing, or am i gonna have to pull the transaxle to replace this seal. I have alot of experience working on cars, but i am more old school. (see attached link) So i am not afraid to get my hands dirty.
