Just need to see if other members concur with this diagnosis and what to do next on it.
It's a 95 Talon AWD with about 112k on it. Only mod done is a K&N filter. Mechanically, it was a purring kitten up until this problem.
We took it on a day trip to Buffalo (12 hour round trip) and everything was fine. Got home, let it sit, and a couple of hours later I got in again to go to work. I accelerated to get up a hill and the car started to severely stutter and blow out clouds of black smoke. Seems that anytime now you try to get up to speed fast, it happens right around when the car hits about 2500-3000rpm. Let off the gas though and it starts going smooth again. You can get up to highway speed as long as you accelerate reallllly slowly. Idle is fine. In fact, the car is fine as long as you stay under 3000rpm.
Anyway, it was an entire day before I found a place to look at the car and even then, it turned out to be a Mitsu dealer. No one else wanted to bother with a turbo car. The dealer's diagnoses was either the solenoid or actuator. Either or was causing the wastegate to not open fully. The part that made me nervous though was the mechanic said, "it's most likely this, but there may be underlying problems that we can't see until this is fixed". That was enough for me to get the car back on a trailer and come home. Upon visual inspection, everything looks good. All vaccuum hoses are hooked up and in good condition. There's enough clearance between the wastegate and heat shield.
It just perplexes me how everything was fine on the road trip and all went to hell after we got home. Well, I can't say everything was fine. There was that ball-busting state trooper on I-81 that gave me tickets for (get this!) illegal foglights (they are the factory ones!), failure to keep right (it was 11:30 at night!), and 80 in a 65.
Anyway, much help would be appreciated. I don't want my next step, or replacement purchase rather, to be the wrong one.
