LE2 problems.....
I've been having a TON of problems with my LE2 350 as of recently. I got a new PCM tune maybe a week ago. Car ran great, idled perfect, no smoking, etc. Now maybe after 15 miles of driving, I go to take it for a ride today and all of a sudden it fouls plugs, has gas in the oil, and smokes like a chimney (so, it's running REALLY rich). I honestly have no clue where to start, I know it's not the tune because it did this before the tune also, and I was hoping the tune would fix it. I have Accel 30# injectors so I know it's no overkill. What could be causing this? I have brand new AC Delco O2 Sensors, so it's not that. I'm this ---> <---- close to completely giving up on this motor, it's been giving me nothing but problems since day one. Any help at this point is good help, thanks guys!
