misfire and no start now.
#11
Well here is the update. i did all new spark plugs and coils still runs way rich. Could have running it for the mile back home have broke something else like an Injector or Maf Sensor or maybe the gas going to the exhuast caused an O2 sensor to fail ?
#12
Something else i forgot to mention that the vacuum line that goes from the intake manifold to the driver side valve cover had popped off on the drive back home it backfired accouple of times just noticed it when i was doing the sparkplugs. Could the vacuum line have been damaged ? thats why its running like crap ?

I would only change #8 fuel injector for starters.
After changing FI and before any start attempt, remove #8 spark plug and crank engine to clear any fuel that maybe in the cylinder. Replace spark plug and start engine. LOOK FOR ANY LEAKS at the fuel rail.
Report back with results.

Should i keep the injectors unplugged while cranking so no more fuel is pushed in to the cyclinder ? Just asking cause i dont work on alot of gas engines. My other 2 cars are VW tdi's

My guess is that only cylinder 8 is the issue. I would not disconnect other injectors.
If you have starting problems once the injector is replaced report back for additional feedback

Any new DTCs
This is a "shot in the dark"
Disconnect #8 injector
Remove #8 plug
Crank Engine and look to see if excessive fuel comes out
Replace plug/COP
Leave #8 injector disconnected
Try to start and report back with results

the vacuum hose needs to be connected too.
