Stuttering

My jeep runs great until the check engine light come on and then the engine will stutter. The light will come and go with the stuttering. Any suggestions on what the problem is and how I can fix it?

My jeep would sputter at start up for the first 2 minutes or so at idle, or until I drove it and mashed the gas pedal down. I replaced the O2 sensors and the problem was solved. I had 78K miles at that point.

It usually happens after I've been driving it. Sometimes, after leaving it over night the problem will go away when I get in the next morning. It's never consistant.

You need to have the computer read and see what codes it has thrown. That would clear it up pretty quick. I think Autozone reads 'em for free.

Which O2 sensor did you replace?

My '99 has the same issue...problem comes and goes.

Plugged in at Autozone and showed a bad TPS.

I'm having a same problem with my '98 Sport, but sadly I don't know as much as I'd like to. If someone could tell me what exactly having the codes read from Autozone will do, what the bad TPS implies, and how severe of a problem this is, that'd be cool.

Or I'd be perfectly willing to accept some free online reading material on the subject if anyone knows where I can find it.

Thanks!
