Recently i was driving my 1991 chevy suburban 2500 with the 454. When it idled, it ran horrible but when i hit the gas it ran great. I looked at the TBI and one side barley sprayed untill i hit the gas then it sprayed. I replaced the TBI, now both sides spray but it does not idle properly, bounces up and down and when i hit the gas it bogs it down. It is impossible to drive, please help me! Thanks
