Car stutters plugs 2 and 3 have black soot build up
Im trying to narrow down whats causing my issues keep in mind the details.
03 svt i recently had a coil pack go out so ive replaced the bad coil i also replaced the plugs and wires and re gapped the plugs so theybare all the same.
Since the coil went out the car has been nothing but trouble trying to fix it.
Digging into it all i was able to find was a vaccum leak on the intake manifold and the plug going to the coil pack had some wires exposed.
That being said i fixed the vac leak and soldered in a new plug double and tripple checking the wiring diagram to make sure it was right.
The only thing i can think out is maybe the crank position sensor isn't working correctly.
So I figured before I throw any more money at it I would ask for opinions.
