Have a 1998 9000 cse 2.3L turbo. there was base boost, brought to local mechanic and it got better than back to normal. brought to dealership and they charged $59 including the part to replace the rusted off actuator arm. anyways, now when you hit the turbo it shutters or shakes. i think the local mechanic adjusted the wastegate on it and now its off. how do I adjust the wastegate?

so does it sound like there is too much boost or not enough boost? I am thinking not enough boost but I have no clue. I found out how to adjust it so I am wondering. I would do it like I time a car. move it, try it, move it some more, etc. thats how I do timing, move the distributor, do it by ear, then run it, improvise as needed. oh well, I will try it out.

I think it's more likely that your DI cassette is failing if I understand you correctly that you are saying that you get hesitation/misfire when you try to accelerate and boost rises. Diagnosis is to swap it for a known good one.

There's a procedure for cleaning/servicing it here
