hello what have you replaced so far?
is the check engine light on?
yes at times and other times no, We have had it checked and it shows nothing.
no it doesnt look like an oxygen sensor it usually has a 4 wire connector and has a plunger on it, here is a picture of where its at on a 4.0l engine
and here if you have a 5.2l
When it is sticking, does it smell like flooding fuel?
Can it be cleaned and with what
Does it need to be replaced?
When it was analyzed it showed it was ok. but the car was running well then.
What does temp have to do with this?
