[Shotimes] How to set the TPS and to what voltage

[Leigh Smith]

Few well respected HC tips to try:
1.    GM top engine cleaner - especially with 246k miles - the "smoke 
screen" method - clears out the old carbon
2.    Pull octane adjust plug under rad hose / cruise control - retards 
timing 10 degrees - or spout plug
3.    Keep convertors hot just before test - 2 min at 2500
4.    If it is a dyno test, talk operator into running it in one lower 
gear, not to upshift to 2nd(?) - keep revs near 3000 - they bogged mine 
down to 1200
My 89 passed w/ 250k on the original O2 sensors & convertors!
