I have a 1998 3.8l v6 at about 79k miles. I had gotten a code for a 6th cylinder misfire and it had been causing some issues. Went ahead and replaced all 6-spark plugs, 6-wires, and 3-ignition coils. And after changing all of that out the car goes up in rpm’s in park and neutral. But once it’s in gear it starts to bog down when ever I press on the gas pedal. I’m at a loss of what to do next🤷🏻‍♂️

 

Sounds like a fuel issue or intake leak maybe.
Hang tight maybe one of our more knowledgeable guys will be along soon.

 

are you still getting codes?

 

no I had the codes cleared by my local AutoZone. When the vehicle bogs down no codes are popping up ether.

 

low or high fuel pressure will not show in codes. test fuel pressure. change fuel filter, dump fuel from filter from tank side in clear container and check for gunk and or water.
