Message:
Can anyone help ... I have a 96 Dodge 1500 3.9 auto around 120,000 mls. Starts great no problems at all but it runs like the old days when the choke stuck (for those as old as me) I have changed the plugs, wires, dist car and rotor as well as the oxy sensor upflow and it still runs like crap.. no vac leaks ot all and I get some codes for misfiring but not since I changed the O2 sensor any help would be more than helpful
Thanks

TPS or a temp sensor telling the comp its cold
will make it run rich
AUTO Zone still does the free scams just tell them
to look at the TPS volts .5 to .7 normal and
the engine temp and IAT sensors they should both
engine temp sensor around 200 +- 10
IAT around 180 idleing
