starting problems
about two months ago i put alluminum underdrive pullies on my 4.6L. almost imediatly i had trouble getting the car to come up to idle after i stared it. but it would not do this every time. so i replaced the fuel filter which wasnt really that old. this seemed to help at first then it did it again. i stared letting the fuel pump pressure up before i tried to start the car and this helped out for a while. then it slowly was giving me trouble until yesterday i cant get the car to stay running with out keeping my foot on the gas and it still runs like ****. again i replaced the fuel filter thinking this could be the problem but it did nothing. i cant help but feel like this was never a problem until i installed the pullies.

Maybe its a leak somewhere in the air intake caused from
improper reinstallation after the underdrive pully install.
Have you tried to reset the adaptive learning?
Disconnect the battery for 20 mins and follow the relearning procedure
in the owners manual...
Sometimes underdrives will overtax an already overtaxed alternator
and cause low output at idle.
Whats the battery idle voltage doring the no idle problem?
