1996 Volkswagen Jetta Q&A
1996 Volkswagen Jetta Question: I have a P1580 code that shows for a scan.
I looked it up and it said that it is a "throotle motor bank electrical malfunction" but I don't have any experience in newer engines. What is the first step in finding and troubleshooting this fault? More info: P0300, P301, P0302, P0303, and P0304 also show which are the random cylinder misfires and I think these are all related to the first code... Am I wrong there? - grumpyrich
No, they are likely related. Sounds like fuel delivery problem effecting the cylinders. Your fuel injection system is having problems. Should have a qualified tech diagnose before you start throwing parts at it. I will say this, finally got one of you asking questions to actually give all the information. Usually have someone tell us about the P1580 code and never share the other codes with us. - raiderron
