Well im a lil unsure of whats up here i pulled upper plenum to change injectors , the gasket was brittle so i ended up not being able to find a upper intake plenum gasket i decided to put it back together with ultra black siliconei waited for it to cure and all. I pulled off throttle body gave it a pretty good cleaning and pulled out stock iac and cleaned it as well didnt play with adjustment just cleaned with carb spray. I got alot of gunk out, i installed new throttle body gasket,gheesh i even re routed all vaccum lines andtiestrapped them all up,i pulled fuses after i finished to clear computer. When i stsryed back.up truck gave me high idle and hunted until it found then would try to cut off then i turned it back on and would idle high about 2500 rpms. I tried resetting iac as per procedure,nothing. Then i installed a new iac and reset again, then truck would run in gear but then in idle after warmed up would idle high in park. I dont know what this could be im going crazy.
It has all new tune up parts and vac lines. Boost guage shoees vac steady at idle and not jumpy. I dont have a scan tool at rhis time. I do however like to addd when your driving it has power no bogging no lack off accel its just an idle isdue. No popping. Could it bethe fact that i used silicone to seal upper intake plenum to the lo. If so im goin to have to get paper to make gasketwer the
