My 04 grand cherokee 6 cyl has lost power
First it was losing power going up hills and would not shift without letting off the gas
Every day for a week it got worse
Now it will not go over 2500 rpm's even in nuetral
If I new where the rev limiter was I would try to change it
I also think it could be a clogged catalytic converter but there is plenty of exhaust coming out the tail pipe
Any suggestions would be appreciated
Thanks
Bob

Check the fuel pressure and report back.
