Hey guys im going to be going through emission's tomorrow! Is there any advise that you guys could give me to help PASS!!!! Car is a 91 gsx all stock except free mod's!!

Thanxs man, Whats a good octane I should run?

91 is the highest they sell at local gas station's but I have about 5 gallon's of 101 octane witch one should i use?? Would just the 91 be fine?

Also I just went to autozone to get a PCV valve and I noticed that you can blow through both ends!! I was told that your not suppose to be able to blow through both ends! Is this true???
 
If your car is in decent shape, you should be fine.

-Drive it around for about a half hour before hitting the smog station.
-Replacing your PCV can be beneficial if it hasn't been for awhile.
-A good fuel additive can be your friend too.
 
Higher octane won't make your car run "cleaner". Unless your car is knocking, 91 is perfectly fine. And yes, you can blow through both ends...What I believe you're referring to are crank vents (which are one-directionial).

No. You're fine. Go pass emissions, if you fail, come back here and trouble shoot. We'll help, and the second attempt is free.

Good luck though!
 
Thanks guy's

Hey UofACATS, what part of tucson are u from??

Hey guys last year i took the car down and it failed on the first try but then passed on the 2nd. I just went to take my car down to emissions today and i failed!! My Carbon monoxide and Hydrocarbons were both to high. Here in AZ these are the only 2 they test for.

Im afraid i wont pass with all my mods.

Help me out guys what do you think i should do??
 
Did you go to the DMV with the awd rollers??? Avoid that one and all they will do is the idle test and pressurize the gas tank.

Is your cat in good condition?
 
No i went to the one on greenfield they just did the idle and rev it up to like 2500 rpms. Im thinking i was running way to rich so i tuned my Low fuel trim to 139% so i hope thats lean enough for them LOL. My cat is also good.

Im going back down there tomorrow morning around 10 and hopefully ill pass this time!

I also retarded my timing a little bit to see if that helps.

Update: Well i went back this morning and i did better i passed the (CO) carbon monoxide but i still failed the Hydrocarbons! The limit is 220 and i blew a 324.

I think i may have leaned it out to much causing it to misfire a bit. My fuel trim was maxed out at 139.

What do you guys think i should do try and richen it up a little bit then go back again for the 3RD time!

get 2 bottles of HEET and dump them in your tank and drive you car in high RPM for a little bit on the highway then go. get that cat nice and hot and the HEET will keep it burning clean. the first time i went with no cat on my car I quadrupled the legal limit after i put a cat on and that HEET stuff i almost got it to 0 on everything it was amazing my car went from being the worst thing for the environment to the best thing
 
Do you have E 85 in AZ? If so make sure to put 50- 50 gas and you will pass for sure. If not get a bottle of Sea Foam, and run it through your vac lines.
