Backfire
Over the last 2 days my car has been backfiring under part throttle under load. When in neutral there is a miss when revved high. My fuel pressure is at 38psi with vacuum line off, timing at 10 degrees. I have cats, long tubes. Had an annoying small leak that was like a ticking sound before. Could the backfiring be caused by this?
My plugs all looked good, tan colour. I don't know how to check plug wires, so that could be a problem, but they all look good.
Any suggestions?
