[Gmecm] 454 TBI 1988 suburban

[David Cooley]

somewhere between 650-750
if it has a code for tps too low, the idle will be bumped up.
I'd check the TPS... voltage should be between .5-.75V at idle

	Hi does any one know what the idle rpm should be ? I put a 4 wire o2
sensor in my truck. Now the idle isn't right it seems to fast.I also have a
fault code for the tps being to low. I can't seem to figure whats wrong.I
have A link plus to look up codes and info from computer. If anyone can help
with info that would be great. JASON
