Problem: 1999 Corvette 5.7L stalling when starting from standstill, even when giving it enough gas/torque
Background: I have a 1999 Corvette with 21,500 miles on it. As you can tell, it dosn't get much use, it must be jumped about evey time I use it.
I went to start it for the first time after a 4 month winter nap (I live in RI, and it gets pretty cold where the car is stored). The car started fine (with a jump), but when I tried to start out in 1st gear, it stalled. I restarted and tried to go in reverse, it stalled. I restarted and tried to start out in first gear after giving it alot of gas, it went a little, then stalled. I did the same and let up very easy on the clutch, and it went a few feet then stalled. I restarted the car and left it in neutral and reved the engine, and it reved up fine, but when I put it in gear the engine sounds/feels like it dosn't have enough power. My parking brake is not set, and I don't think it is stalling because the drivetrain is frozen/rusted/brakes are locked. In total, the engine ran for about 60 minutes today. The car putters out when it stalls, not stops instantly like the clutch was let up to fast.
I use 87 octane gas, but I've never had this problem. I put in premium gas every few fillups. This is the first winter I had the car outside for the whole winter, but it was stored under an overhang. The car is full with gas. The air intake is clean.
Could this be a fuel problem? Due to me using cheap gas and having it out on a cold winter? Due to 10% ethanol in the gas? Could it still be a fuel problem if the car revs up strong in neutral? Could fuel injector cleaner and octane boost solve the problem?
Thanks for your help,
