Replying to: Sizzlerdon (Dec 16, 2008 1:34 pm) I have the very same problem. I have changed, TPS, MAP, MAF, EGR, fuel pressure regulator, spark plugs, wires, plenum, lower intake gaskets, PCV, coils. My ignition module was checked at Autozone and turned OK. Compression reads 195, 190, 190, 190, 190, 200. I wonder if I may have a broken valve spring or faulty knock, crank, or cam sensor, Did you find the problem on yours? Thanks.
