Cracked intake hose. yep i had that same problem...go figure??? I also had a hole in my exhaust right below the header where the O2 sensor is. for two days i had to start out in second gear. No good for racing.
I spent just over 500 dollars in all in two weeks, first 127 was for my two serpantine belts before it was jerking like that, and then another 390 for the pipe, hose with installation and labor after it was jerking like that. It´s getting dirty air and is probably not liking it, that´s why it´s jerking around. If you want to get a cold air intake, nows your chance.
