Hello. I'm new to the forum. I have an 82 CJ7 with a fresh rebuild 258 and the Hesco MPI installed by myself. At low power the engine runs fine. But under load, say going uphill or when giving a sudden throttle input in a higher gear, the engine begins to misfire or cut out as though one or more cylinders are not firing. If I ease up on the throttle it recovers. If not it shudders pretty bad until I do. If I go easy on the throttle the problem does not occur. Only under load.

The crankshaft position sensor is a two bolt type so no adjust
Hi, I have a '89 Wrangler with the 2.5l. It pops/backfires back up through the intake whenever I give it throttle. There are no vacuum leaks. I have replaced every sensor.

At this point I found excessive play in the distributor when rotating the crank, so I pulled the timing cover and found the chain to be stretched, and the cam sprocket and crank sprocket timing marks were mis-aligned. Aha! I said, and replaced the timing set- I set the crank to #1 TDC on compression, rotated the cam forward so that the marks would l
