So i bought an XJ a couple months back and within a week of driving it, it began to stall out randomly while driving thru town. Since then i have replaced the, cap&rotor, fuel filter, CPS (cost less auto), front O2 sensor, and ran a bottle of fuel system treatment. At this point im wondering if i should just take it to a local shop and get a diagnostics for $100bucks. Whats your guys thought on this? or am i just overlooking something minor.

 

Try the IAC and the TPS.

That may or may not help you, but it won't cost too much...

 

WOuld you recommend changing the entire TPS or clean? as for the IAC i did take it off wipe it down with a towel and reinstalled it.

 

Mass airflow sensor maybe. Otherwise I'd get a blutooth diagnostic tool and do it at home for less. Doesn't autozone or OReilly's run a diagnostic for free?

 

TPS is only $34, so I'd just get a new one.

 

I believe your thinking of the Check Engine code reader

 

You may be correct. But if your engine is just stalling, there should be at least one code stored in there I would assume.

 

anyone else?

 

It's not the mass air flow sensor...it does not have one.

 

This

 

What's to the right of the throttle body if that's not a mas?

 

How far to the right? And from what angle/vantage point...?
The TPS is directly to the right of the throttle body if you're standing on the right side of the car.

 

If you're standing at the front. Between the intake manifold and the driver side fender. Right next to the throttle body. Now that I think about it, I'm pretty sure I'm wrong. Is that the map sensor?

 

Take a pic.
Jeeps never had a maf

 

Any CELs op?
