'82 Elky with a 350 crate replacement engine, stock Q-jet. Failed smog (miserably). Codes 21 and 41 have set. Rather than replace the TPS in the old, gungy carb, I bought a fresh carb from I-5 Components. To get the TPS voltage down to .48, I have to bottom out the adjustment screw. IS THIS NORMAL, or do I have another bad or improperly-installed TPS? The code 21 keeps resetting, even with the voltage reading .48. I'm concerned about the adjustment being bottomed out to get that reading. That just doesn't seem normal. Any ideas from the Q-jet experts?
