Question about 1996 Jeep Grand Cherokee
1996 jeep cherokee sport 4.0 L it will stall sometimes and start back after holding gas pedal to the floor, runs rough for a few seconds then smoothes out. also can drive it short distances and cut it off and when I go back to crank it I have to hold the throttle on the floor until it fires the have to hold it at about 2000 rpms to keep it running. sometimes it runs rough for a few seconds and sometimes I have to restart it several times like above before it clears up the rest of the time it runs fine. i have also had it try to stall at a stop sign, usually I can give it some gas and it clears up. any ideas?
It looks like your engine is having an over rich fuel mixture maybe, thatswhy when you press the pedal to the floor it starts becouse you allow lots of air to help clean the mixture while cranking, also you should have black smoke in the tailpipe until it cleans up and runs fine, i think youre having a leak in one our more injectors you should check them first for proper seal under pressure these is done in an injector test machine, second it may be a defective map sensor these trucks some times have a bad map and dont give a MIL (malfunction indacator lamp) and last but more rare to be is a blocked fuel pressure regulator chek fuel pressure it should be between 38 and 45 psi and it shoul hold these pressure when you turn off the engine if pressure drops fast its injector seal problems or fuel pump check
