My truck will not go over 15 mph and it sounds like it's misfiring possibly but If I stop and turn it off and on a couple times then it works fine any ideas?
Normally happens when I come to a
stop it starts running rough but it
doesn't die, then it won't go over
15mph till I restart it a couple times
the EGR if stuck open may do something like this...it would be no trouble to inspect it and see if it operates normally, or is jammed up with carbon~...use a little brake cleaner and an old rag to put it right~
If you've a vacuum tool, would help you to check the operation of this....and the fuel pressure regulator....(which also operates off of vacuum)~
map sensor on throttle body may be bad
checking the iac tomorrow, just realised that it will idle up to 2000 or a bit more, it will go way down under 1000 then go back up, not even hitting the gas pedal, then it pops in the exhaust and shakes the truck and engine. if its running rough, and im driving it, i can hit the brake to the floor and it will still move slowly, like 5mph..any ideas?
Your catalytic conversation is clogged
Converter sorry autocorrect
I have Durango doing same thing! Just took off the cats and it’s still doing it. I realize with the pipe off and the o2s unplugged it’s not going to be great but need to know where to go from here. Haven’t cleaned tb, egr, or checked vacuum, but no check engine light
