For an 86 LeBaron Conv. with Turbo: 99% original. Had the car since 1990 and this is the first time it started doing this. The engine "surges" in other words the RPM goes up and down without touching the accelerator. This is damaging the trans when it slams into gear at (estimate 1,500-2,000 rpm), or I wait until it just goes back to normal in idle, sometimes 3-5 minutes of just high RPM's. Have to turn it off in gear to stop dieseling after turned off with key. Seems to have a mind of it's own. I know I'm not the first one with this goofy problem. But no one but me can drive it because it isn't safe in traffic. What part(s) need to be replaced? Thank you in advance for your support.
