So Tuesday morning before leaving for work started the truck came back and it was misfire crazy it had rained the past two days so I assumed something go wet and it would go away so I gave it throttle and it had no power and felt like it wanted to turn off so I took another car to work



got home and started the truck again it idle normal no misfire and then it started again 1 min later had a code for a p0300 and a p0442 so I went and changed the purge solenoid and did the spark plug and wires and maf sensor



I assumed hey maybe hey maybe a tune up turned it on after all that and waited and nothing still misfiring and stutter so the next day I changed the ignition coils and started the truck and same thing misfire and stuttering no power





so I just kept reving it up pulling up and backing up in the drive way and eventually it stopped misfiring and I could make it out the drive way I did a couple laps around the neighborhood and it worked like Normal so I parked it



later that day I took it on the highway see how it would do got it up to about 80 felt fine maybe 20 mine drive was getting home and it started misfiring and stuttering again and had no power again sounds like it wasn’t to turn off but I can give it throttle and it well stutter and then take off out of no where I don’t know I’m kind of lost any advice helps thanks

 

Welcome to Chevy; you need to psot your vehicle details

 

I would check the TDC sensor as when it fails it can provide intermittent problems with the spark out of time with the firing of the plugs. Inexpensive part in terms of the part and the labor to replace. Often overlooked as it is only in recent years that they have been in use so most people are not aware of their existence.
