ok guys here is the prob.. my car at an idle has a bog when you rev it .. not a bad bog but a quick bog then a slow rev ... the car pull ok until 4500 then it acts like its detonating really bad ,you can feel the car slow..it just doesnt pull like it should and when the car starts to come back down rpm wise the engine runs really rough and the clears up and runs smooth again .. keep in mind this is as soon as i let of the throttle from a 4500 rpm run where the car seams to stop pulling.

all sencers are fine
exept maybe the charge air temp it climbs pretty quick and on the scan master after a little while of idle it read the word hot...at what point does a scan master read hot ? it says its good from -40 to 300 deg..


with that said could the poston t-110 cam im running be floating the valves? i have a set of lt-1 springs on it.. and the rough running when i let off of the car, maybe clapsin lifters? they are new as is the cam ...

any help let me know thanks buddy
