How are you?
I have a 1977 GMC 23ft transmode.
Went to smog it yesterday/Monday and it did not pass.
I drove it about 30 miles on Sunday and about 6 miles on the freeway on Monday before I went for the smog check. I also left it running till the mechanic got to it. I had put $50 of fresh gas in the tanks on Sunday.
The part that it failed is the Idle test which according to the paper was at 928 RPM. I looked at the RPM gauge in the RV and the idle is at 750 in Park and around 600 in N.
So why is this idle at 928 RPM?
It failed the CO measuring at 5.11 and the maximum is 3.00
Any advice on what I can do please to make it pass ?
Thank you,
AJ
