#4090, "cylinder 4 misfire"




          

I have a 1997 Eclipse GS and I've encountered a problem. When I turn the car on you can feel the engine jumping around and it sounds funny. I used a OBD2 code reader and it gave me the following codes.

P0304 Cylinder 4 misfire detected
P0351 Ignition Coil A Primary/Secondary Circuit malfunction

I replaced the coil and checked the spark plug on cylinder 4 and it's sparking just fine but cylinder 4 is still misfiring. The only other thing I can think of is the fuel injector is clogged. After installing the new coil the OBD2 reader gave the same codes. What do you guys think?

Got same problem 1 year ago, sprayed an injector cleaner and the problem solved.

What the hell is this doing in the A604 thread?!? Do you have any indication that this has something to do with the tranny?
