Hi vette friends, having a problem with my 93 LT1. Took it for a rip 2 days ago started feeling a odd feeling in my rear.
it's was shaking and wobbling with a little bit of noise. I did research bad differentials it doesn't sound like that so much. Could it be there is no oil in my TC the reason to all my problems I having.
​Would this cause why I have a major loss of power what happen when I step on the pedal the car lags even is hesitates were it feels like it has half the power with a bogging sound. I just had a full turn up one oil change ago and recently inspected. The morning I checked all my hoses, wires and fluids. I find out my clutch fluid was really low so I filled it an went for a rip still having that noise and major loss of power. No light came on wit in That 4 miles. I know it can be 10 different things or just one thing with signs to a big thing just don't know and could use some insite an help. This being my 1st vette I'm still learning and need some veterans wisdom with c4s.

First thing to check is fuel pressure. If it's too low, that would account for the power loss.

Re the rear noise, check the wheel bearings. Jack it up, grab the tires at top and bottom, and push/pull to see if there is any movement.
Also check the level of the diff fluid. Even if that's OK, perhaps it doesn't have the posi additive in it.

 

Stick with one thread fuel pressure would be the first thing but bad o2s and the resulting bad cats would be my guess. And pick up he *** and check for wear and slop.
