WJ rough idle, NEED HELP ASAP!!!!!!!!
Jeep had a bout 2 1/2 gal in the tank and started idleing a little rough. Affter getting gas the jeep continued to idle rough and when the engine downshifted during accerleration it acted as though it wanted to stall. Let the jeep for multiple hours while at work and problem continued on way home. Check enigne light was already on for an emissions leak, however; once speeds in excess of 25 miles an hour were reached the check engine light began to flash intermintely. As speeds were decreased and engine returned to idle flashing stopped. Repeated problems entire ride home.
Once at the house, I put in park and reved engine the engine sputtered at around 2700 rpm. Restarted engine rough is still apparent though sputtering is no longer an issue while in park. No noise is apparent for engine bay, though a slight exhaust leak may be heard while standing beside vehicle.
Have not had an opportunity to attach OBDII to aquire engine codes as of yet.
Coworkers suggested fuel pump or filter, but I have run the tank dry before and never had a problem. All input would be welcomed.
