My old XJ, 90, 4.0, AW4...now my son's XJ...has been mostly sitting for the last year. Short trips, 'round town a bit, being started and run up to temp every week or so.
He had to register it, and get it smogged. Failed smog on CO.
Allowed measurment (passing) is 1.0
Measured amount 2.16 (failed) at idle.
Measured amount 2.90 at 2500 rpm (failed) "Gross Polluter" staus
So, now he has to take it to a Gross Polluter station to get it smogged and finally register it. It passed all the other tests with great numbers, vacuum, EGR, NoX, etc. all good.
My question: Would the Jeep virtually sitting for a year have an effect on the CO levels if he just started it, and then drove only about 2 miles to smog it without the thing ever getting really up to temp?
It starts, runs and drives like a champ, no sign of trouble, decent mileage. Would getting it out on the highway and "blowing it out" for a hundred or so miles solve my problem...or does high CO indicate a specific problem??
