Engine hesitation at part throttle
I have a 97 Z-28 that has a stumble or hesitation at a part throttle or just off idle. I also noticed when I was coming to work today that at about 30 MPH it would stumble several times. Has anyone had this problem and it has been the throttle position sensor ? Thanks Steve

Re: Engine hesitation at part throttle
I had that. Changed the TPS and MAF, cleaned out the fuel rail and it was POOF! gone.
