sputtering

First time Jeeper, 98 TJ Sahara 4.0, feels like it’s starving for fuel, almost wants to die out when it starts. Thought it was bad gas, but now I’m thinking it’s catalytic converter. Has high miles, I’m learning here, but I’m thinking that’s what the issue is possibly being plugged up? Maybe the...

I rescued a 1997 Wrangler SE 2.5l from a family members backyard. It had been sitting for 2 years under an oak tree. I towed it home put a new battery in it, had to replace the alternator, did a rotor, cap, plugs, oil change and air filter. It's got 197,000 miles on it and has been running...

Lengthy but wanted to be detailed I have 1999 2.5 Tj 5 speed.. it’s been giving me issues lately such as Sputter when accelerating rough idle Randomly cuts off (that just started) My bf and I originally thought the fuel pump was going bad since its more than likely had the original fuel...

I am finally caving, and coming to the forum for help. I have a 97 TJ Sport 4.0. A while back, the jeep would begin to sputter, or sound like it was misfiring when it got up to operating temperature and after driving it around for 30-60 minutes. It was / is super weird, but I would pull into...

Good Morning everyone, I'm new to the forum and the Jeep world for that matter. A little background info for myself, I recently separated from active duty Air Force as a Tanker Crew Chief (KC-135 Aircraft mechanic) of 5 years. I have a little experience in vehicle maintenance but not a lot...

My 2002 sahara will start up normally then after driving for at least 20 minutes and turning the motor off it sputters and doesn't get a lot of power when I try to start it the next time. It is running a bit warm, not in the red but gets up to around 220 degrees. If I give it more throttle when...

Per the excellent documentation, photos and great advice on this forum I was able to (halfway) clean the IAC valve and ole Fern was back up and running, for a week. Same problem came back like gangbusters. So I purchased a new IAC valve and installed, still having issues. Could NOT cleaning...

Successfully solved a low RPM acceleration sputter a few weeks ago but now I’ve been getting significantly lower gas mileage. Normal MPG is about 15-16 monitored for years, but it has dropped to 13 tops. here’s a timeline of the issues and troubleshooting: while stuck in a traffic jam I...

This just started happening a few days ago. The Jeep is running great, idles smooth, no problems. I shut it off, go run in a store, come out around 5 or 10 mins later, fire it up and it idles like crap. I goose it a little and it sounds like crap, almost like it's running on five cylinders. Then...

Hey guys, ive recently had a check engine light come up on my 97 4.0. When I get on the gas my jeeps wants to sputter and seem like its losing power. I can drive it normal just in low rpms. I pulled the codes P0123, P0441 and P0121. Ive done some research and so I took out the throttle body and...

Hey Guys, I was just wondering if anyone had the same problem as me. For about a month now my jeep has been stuttering and stalling at random times while I drive it. I brought it in to the stealership 3 times and they charged me 130$ in total for getting their techs to look at it for an hour or...
