Hi,i have a f-150 1997 motor 4.2 4X4.I had no time to change my (wires,plug,and coil pack)so I went to the garage .before the truck was running well except I had a code of misfiring on cylinder #4 but I was travelling with my truck on on the road without problem.they change my coil
pack and I told them to change my wires and plug.

they gave me my truck back today and after 30 minutes the truck start to run like hell.When I stop at the corner (every stop corner the truck stall)
if I put it on the neutral before the stop and keep my foot on the gaz pedal
and put it on drive I have a little less problem to restart.
on the neutral the idle is ok but as soon I put it on reverse or drive it stall,
need help please,
need my truck for my work,(should have done the tune up myself like I always do
Thanks for your help

 

With the work youve got listed Id check that plug wires are on proper cylinder and pushed on all the way.... check gap on plugs...make sure they used motorcraft plugs. the 4.2 doesnt like anything else
Truthfully Id take it back to them and make them fix it

 

I did went back to the garage and you should have seen me there,they try lost a thing but after 2 hours,I told them don't touch my truck anymore I was mad like hell and before I do something bad my wife said lets go.I told them they are good only to change tires and something else I won't say on this forum,
