Off Idle Hesitation New build, finally got it far enough along to have shop dyno tune.
stock 5.3LM4 with F-body intake and Cable TB. (used)
best way to describe is, feels like an old carb with bad accelerator pump. and TB seem to stick just off idle. I have adjusted the throttle stop a little. but doesn't seem to help. I don't feel the stick when not running, just when running with vac pulling on it.
I guess my question is.
Do these TB wear out and act this way? Shafts maybe?
And could I have bad TPS or something causing the hesitation?
Can TPS be tested or should I just throw another one at it?
Thanks in advance for your time and input
