Well I was on the way to the beach tonight and had to stop and fill up at a Shell gas station, right before there the car had been running perfectly fine and boosting fine and everything....including great AFR's. Well i filled the car up and it took 11.8 gallons so it was really low on gas, I get about 5 minutes away from the gas station and start crossing the 3 mile bridge and then the car started to stutter and fill like it wanted to die. Well I was on the bridge and couldnt stop so I persisted on keeping the car going forward so I just kept giving it gas to get it across and it wouldnt even boost at all. The boost would go up to like 2-3psi and then drop off quickly and the wastegate wasnt opening, I checked all the couplers and clamps, checked all the vaccum lines, re-adjusted the FPR, checked to make sure all the fuses were good. IDK

Could bad gas give these symptoms and if so do i need to drain it or put some octane booster or what in it? the AFR's normally sit at 15.2 on idle so yeah its conservative but now its ranging from 15.8-17.0 to off the chart....damnit im so worried about this.

Please all input will be looked over.

Thanks Josh

 

Possibly bad gas but still I don't think it would run that bad just off some weak gas. If that's the only thing you think it could be, drain it and refill.
