Mt 1988 turbo II runs fine and starts fine, but the idling is terrible. The idle will drop to about 300 RPM then the car shakes and the RPM goes back up to about 600 RPM. Think it might be the fuel injectors and hoping its not a bad engine. And it is toping out at just over a hundred which has just started happenin recently. If you have any ideas prease post. Thanks.

 

TPS is out of adjustment
