What is usually the main problem in causing a RX-7 to fail a smog test. I have a 90 GTU and failed by over 5 times the gross polluter limit, and this is my daily driver. The OMP is bad, would this have a hand in this problem?

 

TPS out of adjustment most likely cause, other would be your cat has gone to heaven.

 

biggest thing to go on these cars is the cat. If you have a shitty air control valve your cat gets no oxygen and starts turning cherry red, all the inards are blown out the exhaust as smoke heh..
Does the seven have like friggen 3 stock cats???

Too pass, read the faq, and get yourself a high flow cat if your current one is toast.

A bad OMP will destroy your car in about 3 tanks of gas. Dump like half a bottle of 2 stroke for a full tank of gas to make up for the bad OMP for now. But first thing you need to do is get a new OMP.

 

I am getting a new/used OMP in a couple weeks. Until then I will premix though, thanks. Does the bad OMP inject anything at all?

 

The FAQ says to dump 2-3 bottles of alcohol in the tank, what kind of alcohol. I know this trick, but keep forgetting what kind to use.

 

Jack Daniels does wonders.

 

Thats for me when I fail smog again.

 

 

just use rubbbing alch like about 64 oz or so i used 32 oz but that wasnt eunuff
Make sure you drive the hell out of your car before you put it in becauseafter you put in the alch you need to shift around 3korless
