You need to check the fuel pump.
Bad ignition coil will cause engine to sputter and hesitate on acceleration.
Try disconnection your MAF ( mass airflow sensor ) and if it doesn't sputter when you accelarate, it means your sensor is gonzo.
A car could sputter in the rain if the car needs new seals. There could also be a spark plug or wire that needs to be replaced.
There could be a few causes for a car to spit and sputter on acceleration. One common cause would be the engine not getting enough fuel, so it could be a problem in the fuel line, fuel filter, or fuel pump.
No
Check for codes... It maybe a bad coilpack. Or bad sparkplugs.
Gas mileage also went down and I just replaced o2 sensors.
my 99 Cherokee has a header leak. i know that's a problem but im wondering if that's causing the sputtering. it will sputter on a good acceleration and after transmission kickdown. no backfireing, no hesitation. i replaced the plugs, wires, cap, and rotor and it didnt change the symptoms. if anyone can help it would be apreciated!
check and see if u have a hole in your muffler
Other posts I've seen suggest it is a weak fuel pump and went on to say it was the one in the tank that was replaced and not the one next to the fuel filter under the drivers side of the car. I will try this on my car tomorrow and see if it fixes the sputter.
If a car sputters when it accelerates there may be a problem with the ignition. Another option is that the timing belt is malfunctioning.
not 100% sure, but check your fuel pump
