Thanks tpman

 

The gm/ acdelco prices are high. You can go aftermarket standard motor products and even use a adjustable 85-89 tps on your tb and set the tps reading to .71-75 feedback volts at idle on the blue wire. You can find used iac housings on ebay and tpis makes a housing with no coolant provisions.
you can lookup part numbers at rockauto.com

will the IAC valve and housing , and the TPS fit all years of TPI throttle bodys 85-88 and 89 -92 . Glad you mentioned Standard brand , whats your opinion of Standard brand ( from our friends in China) ? is it junk or decent stuff? Thanks again

 

The standard stuff is pretty decent, looks like I had it backwards the TH69 is the cheaper of the 2 tps and it is non adjustable. The th37 would fit on your throttle body as well it just has elongated holes to adjust it to calibrate a starting point for the maf ecm. The iac housing I believe there is a 85-88 part number that uses a different iac pintle tip. The link I posted to use a lt1 lower plate works well and is a cheap option. If you go that route and need part numbers for building a conversion pigtail let me know and I will post them. The acdelco stuff is mostly from canada or mexico so pick your favorite country.
