 hope i am in the right place for this question
i hooked up the ob1 to my car and no signals at all. here is what it is doing -when it is first cranked it runs great then after it warms and is shut off its like it has too much gas and choked down. once cranked it has to be reved up and sometimes i have to hold the throttle at 1000 to put it in gear after it is moving it is fine. i have change the tps and believe it might be the oxygen sensor but that is an expensive way to just take a guess any help would be appreciated. thanks in advanced.
