Re: 96 XJ Hesitation when hot & cant rev

Well, I spoke too soon. We are just coming up on 200 miles and she sputtered out again and lost about 95% of throttling ability. You can slightly feather the gas pedal and get it to crawl but until it cools down, she's barely drivable. I did get another Spectra distributor CH15 is the part # and installed that the night before last. Fuel pressure holds steady at 48-51 PSI after the filter change. Engine temp stays just under 210 the whole time. No CEL and no codes even when scanned. Im thinking either CPS or the ECU itself? All the wiring & connectors look good.

Once it sits and cools down for about 20-30 minutes, it will drive just fine for another 20-30 minutes until it does it again.
