car hesitates and stumbles
The car hesitates and stumbles when trying to accelerate, it doesn't do it all the time but when it does do it the wb goes crazy lean like 18-20. I was at the track when it did it today, I but some 112 octane in it just a couple of gallons and it seemed to help. It didn't stumble anymore but still hesitated a little bit. Any ideas, bad gas maybe?

Now it only hesitates when accelerateing from a stop when you punch it and my fuel gauge just started acting crazy. it normaly sits at 69psi but now it will drop to 65psi and just a min it ago when I stopped put it in park it was fluxuating from 65-80psi?

Same problem I am having now. runs fine until I make a few pulls then idles rough goes 20 or so on afr and wont hardly even accelerate from a stop light. Then it may clear up for a bit then go back to hesitating. Checked all grounds, now on to O2's and fuel system? any ideas? Thanks
