Murph Idle CO Too High....

Just barely!

 

The adventure continues! I replaced the air intake and the car is running much much better. BUT, at the latest smog test, everything looked really good EXCEPT the CO at idle. Max is 1.00. Mine registered at 1.14, so it just missed passing. This is all so damned frustrating!

 

I just reset the timing a tick between 20 and 22 BTDC (it was dead center on 20), and I'm going to either get a new PCV valve, or, if no one local stocks it, I'm going to clean mine out and have another go at the smog test.

 

I so want to have this car on the road again. Any suggestions on things to look for that I haven't thought of to clean this one last hurdle?

 

PS. Not that it would matter, but I did just replace the oil pump gasket, filter and oil. The disty cap and rotor were replaced last year just before the car was non-op'd.
