Re: 90 wont pass smog

Re: 90 wont pass smog
Tom;
Thanks for the information. The ECM was replaced by the previous owner in 2005. I don't know if the prom was a part of the replacement or not. I will check out the TSB.
Thanks again

Re: 1990 ZR1 fuel rail "O" rings
Thank you very much. If these are the large ones, 7/8"OD, 5/32"thick, 5/8" ID that would be them. I'll do some checking and get back to you.
