Have a 12/89 EA auto 3.9 with Throttle Body injection.
When you start it will not idle unless give bit of throttle. Changed power steer sensor - no change. Swapped the TPS's over - - no change. Disconnected wiring to MAP - IT IDLES OK. Does this make sense? What is effect of MAP electrically disconnected? Any thoughts? Richie.

Yep, found how to check codes on this thing & got #22 - MAP out of range.
Stuck new one in today (worth more than the car) - all goes great. Thanx. Richie.
