1998 - engine was brand new - built by me.
2000 - never got called! :)
2002 - did a little better, installed a new catalytic converter and did a little bit of tuning.
2004 - Here's the 2004/2005 fiasco.
2006 - something is very wrong. Car is unchanged since passing the test in 2005... the idle test. This year I'm back on the dyno. First off, the standards have gotten more strict on HC and NOx - seems a bit odd to me that the standards for an 18 year old car have gotten TOUGHER. But forgetting that... this thing failed BIG TIME. Just look at the results from 2002. I took the test without doing anything special to the car first... but I have a new Random Technology catalytic converter to put on, and I'll do plugs, wires and an O2 sensor, put the factory chip back in... but I wasn't even close to passing. We'll see... I think the carb is the biggest problem. This other problem is that this is the first time the car has been on the dyno since the manual 6-speed trans was installed, and the guy running the test was having "issues" driving it.
2006 (part II) - Re-took the test today (April 5 2007) and passed. I've added the results to the 2004/5 page because once again I ended up taking the idle test instead of the dyno test, and so the values will line up with the data on that page.
2008 - we'll see what happens.
