Failed emissions - HC and CO
So I took my Fd in for its emission test here in Va. It has passed with flying colors for years. This year the HC and CO were more than double the allowed limit.
Nothing had changed on the car, I have a 6,000 miles on the new engine and there was nothing that had changed. So after I failed went to the car wash to get her washed, and she completely died, no electrical power. Jumped the car and got it running, this was strange as the car lives on a trickle charger.
So I had the battery replaced and found out that the positive terminal was broken. I got a new one from Nissan( I know I didn't want the whole fuse box that Mazda sells with it).
This new terminal fixed the problem and she passed with flying colors, the tech has never seen that before, and didn't know a bad battery connection could cause sue huge issues with the HC and CO.
I did buy a high flow cat thinking the stock cat was finally toast. So that will go on sometime soon just for fun.
HP Mods on my rx7 are m2 intake, M2 medium IC, DP, RB catback, Power FC tuned by KD rotary. Even with all this she passed with darn near zero pollutants.
Not bad for a 21 year old car.
