Is that the ebay special 4 barrel throttle body? That's the one I'm using and finding the correct sensors for proved to be a slight challenge since it didn't come with any information. Mine uses a Ford TPS, something from a late 90s explorer. I went to the junk yard and snatched a few and cut the harness to get the connector. The IAC is a from a GM product, late 90s as well. Apparently GM made them with a brass plunger and also a rubber plunger. The brass plunger IAC won't seal the hole. Ask me how I know.... Lastly, I ended up using a TMAP instead of just a MAP. I think they come off modern era cars, but I'm not 100% sure. I bought my from Ballenger Motorsports. They do have 3 bar for boosted applications.

This throttle body is from Speedmaster via eBay, but it’s different from the other eBay pieces like yours. Part number pce138.1001 . Is your tps the blade type? The throttle sensor shaft on mine is a half moon shape, and Speedmaster sells their own sensor for $100 after shipping. I cannot find any info on an OEM sensor that works with it, but I’m going to the auto parts store hoping someone patient can give me a hand. I really don’t want to be stuck looking for an outdated proprietary sensor 10 years down the road. As for IAC I’m not utilizing that at this time. I’m using the micro squirt IAC PWM output to control my fan which is a bit more important at the moment.
