Hi Gang:
I just went through the Smog Check in CA. Here's what I learned:
My 1990 Carat (263,000 miles on short block) was flagged for a "Test Only"
Station because the State has stuck us with a Problem label. I took the
van in and promptly failed, but only on the NOx....... 1074 ppm vs. 1010
allowed.
Business being too busy, took the van to dealer, had them install a new
Cat, new plugs, cap, rotor, new throttle body and a new AFM (major parts
bought from list vendors). The last two were marginal in any case.
Re-test: passed with flying colors. NOx went down to the 100's ppm.
Dealer: the Vanagon does that. Get it SMOKING hot, then test immediately.
I noticed an erratic idle before the work, which stabilized nicely
afterward.
Haven't changed my oil in a while, but I do run Castrol Synth. - the van
has been sitting a lot. Have a Boston Bob motor STILL waiting to go in,
but am building a castle - it must wait a little while.
That's the dealio.
