I recently got a 94 K2500 Suburban with a big block that had been sitting for a while. Changed plugs, wires, cap, and rotor and it's still got a rough idle, rough acceleration and hard shifts into drive/reverse as well as high idle (about 1100-1200). After doing some research I figured I'd change the tps and see if that fixed the problem. I had to open the throttle to get the new tps on. Now, the check engine light is on and when it shifted into 2nd it slammed pretty hard. Is there a trick to getting it on? All the YouTube videos I watched said nothing about adjusting the tps it was pretty much plug and play. Everything I've read says to adjust it, but I have no clue how to even try that. Any help is appreciated!
