hi there i 'm having some problem figuring out how to fix this problem. my car is 1987 audi 5000 quattro 2.3 i-5 non turbo. any input will be great. also this is the only code i have. it starts but bearly stay on but afer it warms on it great runs beautifully. but if i shut it off and turn it back on i have to floor the gas pedal to get it started.
