Random High IAC counts and idle

[chris989]

Thank you so much for following through with your solution. I have that same issue, though I'm sure I've swapped TPS's since it started. Still, I'll toss in a new one and keep this one as a spare.

The defective TPS came on my SPR throttle body. Maybe it was used/reconditioned,, it was cleaned to appear new. The injectors on the SPR performance TBI failed in one year also.

The TPS that is on my truck now is from the junk yard,, I had it on an old crusty mock-up TBI i was going to use on another build. I was worried it did not have the slots to adjust but it seems ok. It reads .74 volts at idle.

Good luck,

I have one of their throttle bodies also. I've been through a number of injectors, multiple IAC, and I'm pretty sure several TPS. But I need to get it on the logger when it is acting up. I know I've seen the high IAC counts but haven't paid attention to the TPS % or voltage.
