hi got another prob, driving around everythings fine, stop go into a store come out and about 2 min into the drive the gas pedal would go on and off by it self just a little. if felt like a boost leak but its not then down the road it got even worse. i wasnt able to go over 30mph in any gear, the check engine light would keep coming on and i would bog down really bad and it was shooting out black smoke when my foot was on the gas and it would start to bog.
