I already cleaned the maf and replaced the iac. I checked the tps voltage and set it to .98 volts and reset my idle. Any help would be awesome. I can't find a vac leak and I put a gauge on it. At the distribution block I have 17-18. Please help.
That is pretty good vacuum so it doesn't sound like a leak. I am leaning towards thinking it is just the vacuum dropping when the trottle opens, and thus the fan not receiving the signal and cuts off.
Might be someone with more HVAC knowledge than me who knows differently. But either way if that is your biggest concern on a 20ish year old vehicle, be happy.
