That makes me lean towards the 02 sensor.

I will change out the o2 sensor today, thanx dude you deserve a medal or something

When you unhooked the 02, did it make it run differently?

i unhooked the o2 and it did not run any different.....

What brand O2 are you buying?

My local auto pars store has the bosch o2 i will probably get that in the meantime and special order the ac delco one online......i need this car to run nice immediately, the wife is already talking about buying that Jeep Commander......my pockets are sweating bullets as i type....

You'll regret that Bosch O2 very quickly.

I got the AC Delco for 42.00 as it was in stock at the O'Reilly'* here.......Now i need to know what wrench size the o2 is....?

I think it'* the metric equivalent of 7/8 but I maybe be wrong.

www.rockauto.com - Cheap AC Delco O2. I haven't had the Bosch failures alot of people around here talk about.... but thats because I took the advice and avoided it like the bubonic plague.

As for the wrench size.. I bought the O2 socket. It'* great cause it has the cut out like a line wrench. If you don't want to bother with that, a crow'* foot looks like it'd work too.
