When the car warms up to normal operating temperature it stops reving. It revs up to 2k rpm and drops back down. Then sometimes itgoes pst 2k and hesitates and drops back. What could be the cause of this problem and how can it be fix?
There is also a bad exhaust leak.
One more thing, who is a reliable and experienced rotary mechanic

well dude that exhaust leak might be the problem because too much gas is escaping and might make the car rev up to keep itself on..........have u tried revin it to see if it drops after?

2nd gens usually give this problem, but as far as I've experienced it usually flattens out around 3700 rpm's then picks up again.
First fix ur exhaust leak, then if the problem persists, make sure all of ur grounds are properly connected, since grounding may be a source of the problem.
As for "reliable and experienced" rotary mechanics, just check some of the lod posts in the forum man...type in what ur looking for and it'll take you there.
As for me my current mechanic is Dale Myers in Arima. Check the past forums...according to where you're from men could hook you up with someone.

Bless! and good hunting!

i'm not a rotary man eh buh after seeing dale car perform he ha tuh be ah bess tuner

check the map sensor. front right corner by d shock tower. see if its jacked it and has a vacuum source running to it. if its not working u will get a hesitation when u go into boost because it helps control to retard timing. as teen says exhaust leaks esp downpipe leaks can cause it, and vacuum hose leak.

Is it a Series 5? If it is could be a faulty metering pump.
