hey guys. i was out in my car the other day, went for a pretty good drive, and when i was close to my house i got on it for a 2nd through 3rd pull to about 100 mph. as soon as i slowed down the car began to idle high. got home with it still running, but its idle was erratic, surging up and down. shut it off, and could not restart it. grabbed the sct and code p0068 was showing up. did i break my maf or tps getting on it like that? i dont do it often, and i really dont drive it often either for that matter. anyways it will start, but not easily or often, sometimes it just cranks and cranks. sct says invalid for maf counts too if that means anything while the monitor is on. any ideas where to start or just get it towed to my tuner? thanks for any and all tips!
