Idles fine but stalls when i give it gas?

I can start my 1999 jeep xj 4.0 with no problem but when i give it gas it sputters out and then idles rough afterwards. if i start it up then give it gas verry slowly it will climb in rpms just fine and will run great. The sputtering only happens when i get on the gas quick. any answers or explanations? is it a sensor like the MAP sensor or O2 sensor? help please?

Rough idle after engine is warm


Dirty air filter, dirty throttle body...try 2 bottles of gas line fuel injector cleaner...has your car been parked for awhile? Heet gas additive will work on any low gas tank sludge that you may have. Hope this helps.

Just replaced starter on my car but now its idling rough and running rough sputtering


Try cleaning the throttle body open the throttle all the way and use a tooth brush with carb cleaner clean it good then wipe it out with a clean rag. Start the car might have to give it some gas keep it running if it wants to stall then let it idle on its own for about 5-10 minutes this will relearn the base idle.

Driving along just fine, then surged and died. Restarts fine, idles rough, give it gas and it just chugs and sputters. No power to move itself. had to use 4 low to get it off the road.


I would suggest you try replacing the fuel filter usally located under the driver side of the truck inside the frame. If that is ok then you may consider the fuel pump in the gas tank.

1992 Chevy S10 2.5L-4 cylinder. just started today outta no were. it idles really rough and pops then when i step on the gas it sputters and pops also smokes a little. help please..


My 1990 S10 pick-up had a similar problem too. It would start up fine (while the engine was cold) then once the engine warmed up it would idle very rough, sputter, and even stall out. My grandpa and I found what was wrong finally. The fuel distributor had been cracked, so when the engine warmed up it would miss (giving either too much or not enough fuel). So I recommend that you check that. Hope this helps.

sounds like a ignition problem, try new cap rotor and wires and plugs if this does not fix your problem it is either your coil or distribitor

1996 Jeep Grand Cherokee stalls when brakes are applied


My 2000 Grand Cherokee had the same problem, without all the sputtering, it would just die approaching a stop. We could only keep it running by slightly pushing down on the gas petal when coming to a stop. I replaced the Throttle Position Sensor, but that didn't change anything. A new mechanic I found replaced the Idle Air Control Valve, and we've had no problems in a week.
