Hi There, I'm Clayso a certified master automobile technician with 30 years of automotive repair and diagnostic experience.The 24x crank sensor behind the harmonic balancer can cause a misfire at low rpm's and during acceleration. Have you checked compression, also have you determined which cylinder(s) are misfiring?I hope this information is helpful. If you have any questions let me know. You can reply back to me through this thread at any time.Kindly rate my assistance in a positive manner so I may have credit for helping you.Positive ratings are greatly appreciated.Thanks.

You can check for spark from the ignition coils with a test light clipped to ground. Hold the tip of the test light about a half inch from the coil tower (with the plug wire removed). The spark should be bright, crisp and jump the ½" gap. Increase the gap to ¾" and see if the results are the same for all 6 coil towers. This will help determine which cylinder(s) are misfiring.
