install reman. 2.7 in the car last week idles great and runs great but the motor hesitates at 2400rpm like it has a rev limit protection. put new cam shaft sensor in, but same results. will not rev above 2400 without breaking down, whether in park or diving? any ideals

 

I supose you could ck fuel pressure and pressure regulator to start. Id have to think a bit more but thats a good start/somthing that needs to be eliminated.

 

fuel del. good. this has me scratching my head. took the old motor out put the reman in an now i cant get the motor over 2400rpm in park or driving down the road.

 

Any advise will be helpfull

 

Is your year a vacuum controlled fuel regulator?

 

im not sure on that one. will have to get back to you. what r u thinking?

 

clog exhaust? that tend to keep RPM bog down. Maybe check compression too. U never know if the Reman Company screwed up their timing or something.

 

I looked it up and your year is only regulated at the fuel pump (that’s where the regulator is mounted). Here are a few other items to ck:

Ensure 58 PSI fuel pressure (if not done already)
Check for vacuum leaks at heads etc
Ck TPS and TPS circuit
Compression test (as previously noted)

I assume you do not have an engine code, but there can still be a possible sensor malfunction. The PCM may not trip code if the signal is beyond threshold range that its monitored.

What have you done/looked at already? Give a list and let us know.

 

code is po344 cam sensor so i put a new one in, cleared the codes but as soon as i fire up the motor same code keeps tripping the check engine light. fuel pressure good but will check the other stuff this weekend, and let you know. thanks for all the advice, and keep throwing it out there, i will know more this weekend

 

Ok...ALWAYS troubleshoot the engine code first! Ck continuity between the sensor and the PCM. You nay have also installed a bad part. Work to fix the fault and you will probally be gtg.
