Yeah yeah, it’s an XJ. XJ forums aren’t nearly as helpful as this one normally is, and we have tons of underhood components in common so here goes.
Friends’ daughters 98 Cherokee has a really hard start & rough idle. If you ease up the throttle, it smoothed out nicely. If you stomp on the gas, it bogs down and dies or comes close to dying. You can see it running rough in the video, it shakes pretty bad at idle. At higher RPM it smooths right out.
Battery is good, took off the starter, cleaned it up & tested it, cleaned up a couple of grounds, same result. There was a TPS code but we replaced it. Code hasn’t returned (yet) but result is still the same.
Any ideas are welcome.
