[matt98eclipse]

We have a fresh rebuilt built 420a we just started it right now and noticed everything sounds good! BUT the rpms keep climbing for some reason?? It went all the way up to 3500rpms and we thought it would be best if we shut the motor off! Please help guys were in the process of trying to figure out whats wrong right now!!

What could cause this?? I checked the throttle body and its fully closeing.

Updade: The car has close to 50 miles on it and has had 2 oil changes aldready! Everything seems go be going good EXCEPT today! While driving it today i noticed the rpms just started bouncing from 1500 to 1000 back to 1500 really bad so i pulled over and opened the hood and DAM i noticed the timing belt was all extremely loose and was pretty much off the cam gears!! So im thinking the tensioner or tensioner pully is messed up.

What do you think bent valves???
