Here what is going on, I have a 1997 LT Tahoe and while driving the RPMs jump and then all most die to about 5 RPMs and it also chugs for a few revaluation like something is stuck and then runs fine for another 30 to 40 miles and does it again. and some times at a stop it will act like it going to die the RPMs drop off?

Now it has a squeal coming from the belt or AC compressor. have not changed belt in forever. But if I put dressing on belt noise stops for a while so I think the noise is belt?

I have had it in to GM they set the timing, put in a new set of injectors, has new wires and plugs.

Auto zone said it had the cam sensor or crank sensor are loose on their mountings? code P1345

Just a few min ago I was working on it and notice a broken plug running from the AC compressor to the I think it is
Any thoughts would be of great help as this might be my house soon if this keeps up smile. thank you all, Leonard
