Question about 1998 Jeep Cherokee
Some months back my 4.0 liter began shutting down and backfiring loudly which in turn totally demolished my cat.converter and muffler.
so i went and replaced them both at a whopping $320.00 the mechanic ran a hand held diagnostic on the check engine code and all it would tell us is that there was a high manifold pressure after leaving the shop i drove maybe 20 miles down the road and it blew the converter and muffler again so since then i've driven it this way just to make ends meet until i could take it in to a dealer and have the larger diagnostic tests to try and determine where the problem is originating but the dealer wants me to replace the cat-converter and muffler again because they cant get an accurate reading this seems like nonsense to me!!! please is there any help to end this ordeal
Could be map sensor too, but don't start changing sensors without really testing them.

How does it run when it's cold?
A bad crankshaft sensor could be the culprit.
