TPI Rough Idle
1989 TPI Rough Idle. Hunting idle mostly. I have gone through the entire TPI unit.
New injectors, new EGR solenoid / EGR New MAF, cap / rotor. etc, etc, etc. Nothing left to replace on the upper end. At least it's not stalling anymore, but the idle still hunts all over.
How can you find a vacuum leak in a TPI unit ??? It's impossible !!

Hunting idle
Hunting idle a lot of the time is the throttle blade idle stop is off.
usually ppl try to adjust idle with the blade stop.
there is a procedure in the maintenance manual to adjust it correctly.
