4.6is stalling when hot
 

Hey guys, am looking at a 2003 4.6is with 28,000 miles.

It starts stalling sometime after engine gets to operating temp.

It will drive fine but as soon as you come to a complete stop, the engine will stall.

What could the problem be?

vacuum leak.

yeap, air management, as i am learning myself on my car right now... could be vac leak, or MAF, or throttle...

have you had a chance to read the error codes?

At the indy now...mass air flow signal says the tech.

Hey Ed, am thinking if its a vacuum leak it would manifest when cold also?

where did You find a 4.6is with 28k miles..........brother, if it is for real hold on to that one................ good luck , what color? any other plans for if?[ungrades]...............where in socal are You? I know a few good shops from there when I lived there.

^hey man, sorry, havent updated my profile, the car is in Manila, Philippines. I stayed in Buena Park for a while :)

Yeah, we kinda lucked in on this one. Pops found this one. 1 owner, well maintained. My 3.0 feels like a dog now lol!

Update, after a visual inspection of the air ducts for air leaks and finding none, I went ahead and gambled on a new Bosch MAF. It seems to have solved the problem!
