I have a 1998 chevrolet 5.7 that has a miss that I can not get rid of. The miss happens when I lightly press the gas pedal whether I am at a high speed or a low speed and it has even started doing it when I floor it. It sputters, lightly jerks right before the gears shift and misses. There are no codes up, I can hear my fuel pump cut on and the truck has 210k on it. I have listed below all of the parts that I have changed in the past 5 months…. Ignition coil Distributor cap and rotar Spark plugs and wires Map sensor throttle position sensor Egr valve Pvc valve starter wiring harness new battery 195 thermostat MAF sensor.. I also cleaned the idle sensor and the throttle body itself. I have no idea what else to do to take care of this mis, any ideas anybody? I would greatly appreciate it!
