2002 5.3 spark plugs fouling problem on driverside I have a 2002 5.3 and all the spark plugs on the driverside are fouled (too much gas). I have replaced the fuel pressure regulator, checked the ing power at the injector (Bank1 11.84 and Bank 2 11.81), change the coil pack, swapped the injectors, swap spark plug wires, swapped the o2 sensor, did compression test (all is well) and checked intake for leaks. There is no check engine light on but ran scan anyway... no codes.
I dont know what to do next. Need some advice.
Thanks in advance

I looked through some of your old posts and noticed you were looking for a tuner. Did you ever find one? Since the motor has been out recently and the car has been tuned it could be several things.
You crushed or nicked a wire, coil harness specifically.
The tune is fubar and one bank is dumping fuel.
At first I was under the impression that this was a virgin engine bay but as it turns out, it's not. So my thinking goes the way of probable cause.
