Ok....so my car today started to act up. I was going about 35 for about 3 minutes and when I kicked it up to 55 it was real sluggish and the tach danced around a little bit and was able to get to 55 no prob but it was like gasping to go. It did this again later tonight when I was in a 45 area and needed to pick-it-up to 55. It idles fine, starts fine and shifts ok. I whomped on it to see if I just needed to clear the carbon and nothing.

I just had the sending unit, fuel pump, fuel filter and lines all replaced. Im not sure what next. I was told that the plugs and wires are not that old.....but I'm thinking about changing them this weekend.

My wife told me that the other day when she got gas she put a tank of 87 in and I have been running 93.dh2 Could this posibly be it?? I'm lost for thought on this!!

Premium only in a supercharged engine. That could be the problem. Test your coils, it sounds like a weak spark.

I went and got a "fuel treatment" from Autozone. Should I put somethin in extra. Im afraid to drive too long on this. I am hoping I will around a half tank tomorrow and go fill her with 93.

.....I also noticed I only got about 60 miles on the clock for 1/4 tank! EEK!

Lower octane, really drops mileage, even with the higher price, it'* still better to use premium. Those octane boost things are a waste. they might add about .2 or so to your octane, not worth the price. Drive normal and you will be fine with the 87. Get half a tank of 93 and that will get you to about 89 or 90
