Ran into a problem that I need help diagnosing. Took my car out for a spin yesterday and noticed that when I get on the gas in normal or spirited driving it is fine but when I lay off the gas the car starts to jerk back and forth almost like the car is in too low of a gear. When I try to put the car in a different gear and the RPMS climb on the gas it is fine but as soon as I get off the gas and the rpms fall to about 2200 I get the jerking motion again. I have a 383 motor with a camaro 6 speed in it. Brand new driveshaft with new ujoints and completely new MOSER 9 inch rear with trutrac and 3.73 gears. The pinion angle has been set up by a shop that knows what they are doing. I dont know how old the clutch is but it is hydraulic and shifts very smooth with no chatter at all. I have heard everything from motor mounts, to tranny mounts, to u joints to pinion angle, to excessive play in the rear end setup! I am praying that the rear is not the culprit since it is all brand new from Moser and I have heard nightmare stories about them when it comes to fixing or standing behind their products..
Just looking for the best way to go about diagnosing this problem so I dont run around in circles with it. Any help would be greatly appreciated.. I know it is not a fuel issue. It is very apparent in first gear going around a parking lot. So bad I have to put it in gear and immediately put my foot on the clutch to coast around with the throttle off.
Thanks
