Man, every friggin time I go to do emissions lately nothing goes smoothly.....
Took my new-to-me '97 to get the test and then to get plates/registration - the usual drill right? Nope. Keep in mind that the previous owner had the emissions test done in July '09 with no issues.
Mike (Crunch) took his rig as well - we used the 32" tires from the MJ project leaving our 35's at home.
Mike starts worrying because his rig sometimes has a bit of a misfire/rough idle on start up and thinks it'll cause his to fail. Nope, he flies right through - gas cap test and all. I'm feeling pretty good about my upcoming test.......
Mine gets plugged in, the tech sets it up on the dyno, rock shields in place, fan placed and adjusted, sniffer tube hooked up.
First test: Failed. Time for the "Second Chance" run through.
Second Chance: Failed. Computer screen shows "Sample duration exceeded limits". I'm friggin' fit to be tied now thinking I'm gonna have to go through all the B.S. of diagnosing why this rig won't pass.....
Miracle: Tech decides he should run it through a 3rd time. Dunno why, nor do I care - I was more than willing to let them have it until it passed! And it
did pass.........
Here's the issue: The tech drove it VERY differently on this third test. I noted that he was easier on the throttle when accelerating when the computer told him to. He let the arrow on the screen stay yellow a bit longer when running up or slowing down the engine speed to follow the computer program. (Unless you've watched the screen for these tests, you won't get what I'm saying here.....). He's got this serious look of concentration as he's driving the Jeep......
I now am 100% convinced that these Envirotest facilities are a huge scam simply because there's no consistency in how the test results are obtained. Yeah, if I got behind the wheel of a test car and flogged it I have no doubt it'd fail and if I drove it very conservatively it'd pass. I've seen these techs drive 'em where it's bucking and bouncing due to quick punches of the throttle and I've seen them be smooth as silk on the dyno.........
Don't get me wrong, I'm grateful that the tech tried his best to have it pass..... but why isn't that the case with all the cars???? I've had an XJ go in for a test and it failed the first time and they sent me on my way - no second chance! What a bunch of b.s.
