i have a 2001 with a 4.2l v6 in it i was driving home the other day when all the sudden lost power, limped it home since then ive put new plugs (motorcraft) new wires and new coil pack, fuel pump was weak so replaced it and fuel filter,also replaced tps sensor and iac valve. with all that being said nothing has helped. ANY ADVICE!!!!!!!!!

 

Drop the converters @ the Manifolds & see if the truck runs better.

 

i just put new hiflow cats on it

 

Engine Light on? if so codes please....

 

it runs so bad i cant drive it to get them checked, i ended up having to put it in the shop
