Marco,

The guy that bought my 87 Civic Si (as is where is) had a hard time getting it to pass. He went to the same testing place 5 times. Failed all 5 times. After the 5th time, he ran it hard to the one at 44th & Macintyre (sic). Passed with flying colors. Moral of the story, try a different facility.

2 bottles of Heet and call me in the morning

Seems to be the trick for us 80 series folks anyway. I always try to spend 30+ minutes at highway speeds before going in for a test. If there is a line, I don't shut the engine down either. I'm skerred that both the LX and the 80 are going to fail when their time comes up

I have changed the oil recently, but am tempted to do it again anyways as you suggest.

Also, I need to check timing

I would definitely check timing, I think this can make a big difference. It does in perfomrance. I am not sure exactly how it impacts emissions that are measured at the pipe.

Usually backing off the timing helps.. at least that's what I understand and have experienced

OK, so tonight I threw in the new Vehicle Speed Sensor and it seems to have helped a lot. The engine idles smoother and runs smoother. The old one was not broken (other than me breaking it while removing it), but I noticed that it was not reading the speed at all. Turns out it was just too far away from the reluctor ring in the Downey adapter thinggie. The Downey adapter uses a stock GM VSS but has a little set screw to hold it in place (kinda hokey). They recommend to measure the air gap between the reluctor ring and sensor and set it to some specified amount. It was silly coned in so breaking it to get it to move was my only option.

When I mounted the new one, I hooked the computer up to the truck and ran the motor with the tranny in gear and the transfer case in neutral. I pushed the new VSS into the housing untill I saw a nice steady speed read out on the computer and locked it in. It was interesting to hear the change in how the motor ran as the VSS picked up the signal and dropped it while I was moving it around.

I am still planning on checking cats and changing oil before trying to go back early next week.

That would have been pretty cool to witness! (Is this why some people call me a geek?)

Best of luck next week man! Keep us posted...

Holy crap, I just changed the oil and it was wayyy overdue. Smelled like it was basically straight gasoline... ok well maybe not really.

The engine actually sounds a lot quieter now

And the new VSS makes the motor run a ton better. I can feel it. Lets see what the emissions folks say this time..
