I Bought A 93 T 100(3.0 Manual Trans.) That Someone Put A 3.0 Engine Out Of A 91 P/U 2WD(auto Trans.) In . I Used The T 100 Harness ,ecm,mass Air Flow,and I Bought A New Tps(and Adjusted),also Changed The Temp. Sending Ass. At The Right Rear Top Of Engine Behind Plenum. The Problem I Have Is When I Start The Truck In The Morning It Idles Down Some But Not Far Enough No Matter How Long I Let It Run Or Drive It,but I Can Shut The Truck Off After It Gets To Operating Temp And Restart It And It Idles Ok But Will Slowly Increase A Little.
Any Ideas , Pulling My Hair Out.
