Is this a swap vehicle? Are you trying to run it with open exhaust?Quote:

just have it towed.Quote:

Well with the o2s unplugged it doesn?t want to run at all?Quote:

If you ran it very long with open exhaust you probably fouled your plugs. O2's don't come into play until it warms up enough to switch to closed loop. Cold start it shouldn't be any different O2s plugged in or not. I think you need to study up on how open/closed loop works with O2 feedback.Quote:
