My name is Josh. I recently purchased a 1995 Jeep Wrangler. I love the thing to death, but no one I know can figure out a problem I'm having with it. It will start up fine, and run great for a while, but after you start driving down the highway for a little bit it will start sputtering horribly, decelerating even though my foot is still on the gas, and backfiring really bad. After about a minute of this, it will straighten out and run fine for a while, but it happens often. I have taken it to two mechanics and it still isn't fixed. One of them tried to access the computer, and it wouldn't talk to their diagnostics tool, I have a feeling this may some how be connected to the problem, but I don't know. Any help is appreciated, thanks in advance.

welcome to the forum. Give us a bit more information, which engine do you have? Also did you take it to a Jeep dealer or just to general shop mechanics?

Thanks for the welcome. It has a 2.5L, 4 Cyl. engine. I took it to two friends of my fathers who are general shop mechanics in hope that they could find the problem so I wouldn't have to shove out the big bucks for the dealership just to look at it, let alone fix it. Thats not to say I wont take it there, in fact I'm close to doing that. I just don't have the money yet...

Does it have an iac motor, IM betting it does and that could be the problem!

I'm sure it does, but would that cause the problem I described? It happens as I'm actually driving.

yes, I believe, it controlls fuel and air. which can cause sputtering and backfiring! I would ask a mechanic, As I am certainly not! but might be worth a look

Hmmm, any thing is worth a try I suppose. Oh, btw to anyone responding to this post, I was able to pull the DTC's from the On/Off/On/Off/On sequence and got the 52** error code, (Oxygen sensor signal input indicates rich air/fuel ratio condition during engine operation.). Don't know if this helps.....
