It is strange that you will pas HC during idle and then have it go up at
speed. This indicates a miss fire condition. You need to check the
engine compression (leak down test-valves), ignition system, and fuel
distribution. A clogged or defective injector or a bad spark plug wire
is the likely culprits.

Subject: vanagon failed CA Smog - CA Help

Anyone in CA (Bay Area)  can help me pass smog?  I've always past with
flying colors but today I failed.  I don't understand why?

Here's what I got for 84 Vanagon that is in great shape:

901 RPM HC max is 150, I got 61; co max is 1.20, I got .13
PASS
2554 RPM HC max is 180, i got 344; co max is 1.20, I got .36
FAIL
on HC

Why did I fail on just HC?  In the past I drove van on freeway to warm
up
before taking test.  This time van sat for about week before I took for
test.  Could this have caused me to failed because I needed to warm up
cataylic converter.  Smog mechanic said warming up makes no difference.

Is there anyone local that can help me pass?
