Last Saturday night I took the Mag out to hit up a car cruise this guy told me about while I was on the Power Tour. As soon as I got on the highway I attempted to get into the middle lane and when I hit the throttle the car bogged down right when it hit 4000rpm. It acted like I hit the rev limiter. It cruised fine at any speed, but every time I hit the gas and got up to 4k, it did this. I have NEVER had any mechanical prbs with my car, it's been well maintained. So, when we get to were the cruise was supposed to be...there was nothing! lol. I had my dates wrong. But, we stopped at Culvers and ate, then headed back home. I did a code check and got nothing so when I got on the highway again I hit the throttle and everything was just fine. I got past 4k with no prbs. The only thing I could think of is that my gas is getting stale? It's under 1/8th tank and the last fillup I used 93 oct. Wait, it can't be stale gas. I drove the car 420 miles on its last outing. So, any thoughts?
