2003 ford expedition 4.6

Asked by Jul 23, 2016 at 07:45 PM about the 2003 Ford Expedition Eddie Bauer

Question type: Maintenance & Repair

My 2003 expo 4.6 started dying and then
restarting during acceleration. It started
saying check charging system so i
discovered the alternator was bad. So i
changed it. Charges fine now but after it
gets to operating temp it starts dying and
jolting again. I have changed three coil
packs, timing chain gears chains and guides,
and now im stuck. The rpms go to 0 then go
right back up. Need help

Could be a bad coolant temp sensor, get a code reading and type it to me, i can only further asdist your trouble through code retrieval.

Its not throwing any codes

Sounds like it is vapor locking check underneath vehicle to see if any part of the heat shield ( this separates the exhaust from the gas line to keep the heat from exhaust from getting to gas line causing vapor lock ) is missing.

Well i thought that. Would a stopped up catalytic converter make it shut off when accelerating?

Could be depending on how clogged up it is but usually a clogged converter you slowly lose power not completely shuts the vehicle down when accelerating.

Or when vehicle reaches operating temperature.

I noticed today that the cruuse control light comes on when it dies and comes back. Funny thing is the cruise dont work
