I had my car scanned because the "check engine" light stays on. I finished swapping a 96 motor into my 95 SE. I replaced the front Knock sensor and the problem remains. I purchased another sensor to replace the rear sensor but I wanted to run this buy you guys before wasting 45 dollars on it and not have it fix my problem.

I check all the wiring to both sensors cleaned the connections, I also swapped the part that sits under the three coil packs (is that the ECM?) .... It keeps getting the P0325 error within 3 minutes after starting the car.

I need to get it fixed because it runs like crap with the timing retarded ... I just don't want to waist any more money buying sensors trying to fix the problem.

Please Help ... Thanks
