Acceleration issues
So on my 98 XJ 4.0 when the jeep is cold it runs ok,but as soon as it warms up the rmps go up and down while idling. Then when I start to accelerate, the engine sputters. and then backfires. I can't get any acceleration unless I stomp th gas then it will go for a few seconds and then continue sputtering. Any ideas what could be the issue?
