Customer Question

I have a 91 chevy 454 with TBI. It will start but will not idle.
JA: Have you checked the battery, particularly the terminal connections? Are they corroded?
Customer: It will start so I think the battery is alright.
JA: What is the model of your '91 Chevy?
Customer: It is in a motor home.
JA: Are you fixing your vehicle yourself? What have you tried so far?
Customer: Yes. I check the vacuum hoses with a vacuum gauge and it checks ok. I have replaced the idle control valve.
JA: Anything else you want the mechanic to know before I connect you?
Customer: That's all.
