only 1/2 an engine HELP!!(coils?)
hi I am very new to thease coil packs and newer engines in general (still love my old I 300) anyway lent my truck to my cousin to move (thought i was smart getting out of helping) he left the lights on and needed to boost it now it has no power smells like raw fuel, I had the codes run and got PO 308,307,306,305 could all those coil packs went at the same time? or am I missing something? Please any help would be great.
thanks
monte
oh yes the truck in question is a 2000 f150 with 4.6 triton

At least take a look at all the injector, and coil plugs first to see if something happened before asking for guesses. All the cylinders are on the driver's side bank.
Maybe there all loaded up with water in the plug wells.
We cant see so you have to do it.
Got to start somewhere!

ok more confused tried unhooking battery for 1/2 hr and checked all fuses they seem fine, then when i restarted it started perfect at high idle(its brutally cold out)then as soon as it heats up it started missing again??? although not as bad yet, but i didnt drive it around yet. I did check as engine was getting hot if the was any steam coming out around the coils from water at the plugs but saw no sign? chk engine light didnt come back on yet but I only let it run for about 5 min as the missin g was getting worst and I could smeel the raw fuel in the exhaust

Somethings wrong with what you are reporting.
The PCM won't let raw fuel through without reporting it.
When there is raw fuel being passed there will usually be a flashing CEL lamp at some point alerting you to the possability of CAT damage from overheating if the excess fuel is burning in the cat.
Powering down the PCM only reboots it, not fix anything.
You may have harness plug problems affecting that bank.

the check engine light comes on and then flashes as the fuel in the cat increases is there a junction between the harnes for the left and right side? it is freezing out there and it all seems to be wrapped I cant see any conector separating the sides but i didnt crawl around that much yet.
thanks for the help, anything else I should check to narrow it down?
