Rough idle
Hello there, I have a 1990 tpi . I have a rough idle, I’ve had it to several mechanics, no luck. Does anyone know of a shop in the Midwest that has the equipment to diagnose a tpi of that era?

Re: Rough idle
Likely bad injectors. Very common on this era of TPI. You can sometimes listen to them with a stethescope but if they are original I would just toss them and get a new set.
