In many of the posts about the off idle hesitation, James Dean has recomended turing the base idle up a bit. I have also seen posts saying turning the TPS a little helps cure the hesitation. Is there a chance that turning the idle up changes the TPS voltage enough at the new idle to change the ignition timing? I can't think of anything else that the TPS would be needed for other than timing. Is there a way to check ignition timing with a timing light? I don't have my Shop Manual with me or I would check. By the way I would like to thank James and Clark for sharing all their experience with us.
