I have a 94 idi with stock turbo here recently it's started acting up I push the throttle the turbo spools up and it feels like there's a slipping somewhere and when I let off it finally catches speeds up can anyone help me diagnose this issue

 

Slipping clutch or transmission? Inspect and repair/replace as needed?

 

If it's a manual, it could definitely be the clutch.

Just bought a '92 with a very similar problem - if you were careful, you could get it up to 60 unloaded, but give it more than a bit of throttle and it'd just start slipping.

Pulled it apart and swapped in a new 12" SMF clutch and flywheel. No more clutch issues.

What was odd was that it sure looked like the clutch plate that came out was OK, but the pressure plate looked wrong. Like it had jammed about halfway "in" and wasn't putting enough force on the clutch plate. Fingers were a lot "lower" than the new plate I installed, with both pieces freely resting on the bench.

 

Damn I was hoping that wasn't the case. My step dad said try replacing the slave cylinder first and see if that fixes the issue.

 

Easy test: get under the truck, and push back on the clutch fork(pushing "in" on the slave cylinder). It should be pretty stiff, but should move slowly. When you release it, it should come back out slowly and take up all the slack.

If you can push it by hand, then it's obviously not sticking.

 

If you're on a budget and near Philadelphia I have a used Luk single mass flywheel, clutch and pressure plate that look in good condition. Real cheap.

 

Unfortunately I live in Texas or I'd take u up on that offer

 

Hey maccrob I did what u said the the slave cylinder didn't come back out slowly just kinda piped back to the position it was in and made a clicking sound

 

It was the clutch cause it went out on me today
