300C won't pass inspection b/c 180 deg thermostat
So here's the story:
A couple years ago, I switched my thermostat to a 180, because the old one apparently gave up the ghost. (I now realize it was only the bad gasket.) As expected, I got the Check Engine light as a result, but pulling out the correct fuse would reset it... no big deal.
Well, I went to take my car for inspection and my guy said, "It didn't pass the state emissions test. Did you reset something?" I said, "Yeah, because I have a 180 degree thermostat."
"Yeah, well the emissions computer knows that there's no memory in the computer and won't let it pass. If you had told me, I would have known to look for that."
So I bought a 202 thermostat so I won't get the error code anymore (I never noticed any difference with the 180, other than that my gas mileage seemed to suffer), but should I know anything before I install this? I mean, is there a way to get the car to pass without all the trouble? (Now that I know that it was just a gasket, I'm mad that I threw out the old thermostat. Duh!)
I searched the forum for questions like mine (I actually used to be a member, but the system wouldn't let me log on with my old username, even though I still get updates to my email from the Challenger forum), so I'm sorry if the question seems stupid.
