I have a 2000 3.8 v.6 Camaro. I was going about 70 the other day on cruise control on the highway when i heard something pop. then i pussed the gas and the car wouldnt respond immidiately the car shut off. i tried crankin it that night and nothing. So about 12 hours later my buddies and i went over to the car and on the first try i got it started, cranked right up. drove it about 10 min down the road and shut off on me. it cranks every now and then but when idling i push the accelerator and it struggles. sometimes after 5 minuutes of idling it shuts off on its own. when i turn the key usually all my gages work but now with the all work with the exception of the 2nd from the left which looks like oil pressure guage. any ideas on what it could be? i just changed the plugs and an oil change. please help its the only transpostation i have left
