stumbles bad, won't rev past 2500 rpm
Hi Everyone. I just got done swapping an '04 SRT-4 motor into my '04 SXT. Basically the entire engine/tranny assembly including k-member, suspension, wiring harnesses, etc. I started it up for the first time today and it started on the first crank and idled perfectly.
But when I press on the gas, it will rev to about 2300 - 2500 rpm and start missing really bad and won't rev any higher than that. Let off on the gas and it goes back to a perfect idle. The best way to describe it is almost like bouncing off a rev limiter, but at 2500 rpm.
I've checked for leaks and everything looks tight. Anybody know what may be the problem?
Everything is stock except for a Stage 1 PCM.
