1991 ZR1 Restore - Help! - ZR-1 Net Registry Forums

ZR1CK · 05-01-2022

Hey kapkanimd, your motor sounds just like mine when I was having the same issue and a code 31. I went through several test procedures, not all that you have, but according to the 1991 Service Manual. Which is by the way, a very important tool to have. And ended up with a faulty ECM. Sent it off to Marc, he fixed it, and then the motor ran as it suppose to. Good luck with yours and hope you correct it before it drives you crazy...cuz it can.
