95 GMC hesitation
Question:
I have a problem with my truck hesitating when you give it more throttle at 1500 rpm. It only happens once the engine reaches operating temp and when you are in overdrive. I’ve checked the throttle position sensor with an ohm meter, I have no codes, injectors are clean, can’t find any indication of vacuum leaks.. I have upgraded to a Jacobs Mileage Master Ignition with cap, rotor, wires and plugs and the K&N filter is clean. I’ve also tried disabling the Jacobs and running stock ignition, but no difference…….help…..brian
Response:
I have the exact same problem with 1994 Suburban (1500). I have replaced the Throttle position sensor, oxygen sensor, battry and fuel filter so far. The problem still presists and I am thinking about taking it to a dealer for diagnostics. I will let you know if I find anything. Please let me know if you find anything.
