Question:
This needs to get fixed but I don't want to be ripped off so I'd like to see what some of you think it could be.
What happens when you put acar battery in backwards?
Failed Emissions results
Gas | Standard | Reading
Nox | 1006 | 1127
CO | 0.73 | 1.70
I have no clue what any of that means but the CO looks really high.

High Nox readings mean that the combustion chamber temperatures are too high, which is a typical result of a lean condition. The high CO readings indicate that there is incomplete combustion occurring. These symptoms both point to a lean misfire, which is most commonly linked to a vacuum leak (possibly any line, intake gasket or a slightly stuck open EGR valve), a weak fuel system (usually the fuel pump), or a weak ignition system (which may, or may not, include worn or fouled spark plugs, bad wires, worn distributor cap or rotor, weak coil, failing igniter, etc. I would take this vehicle to a professional repair facility for an evaluation because you can waste alot of money throwing possible repair parts at it, or most likely spend a great deal less on a professional evaluation to determine the cause and solve the problem. You can find shops rated within 3-4% in the nation on ASE.com. Look for a Blue Seal rated facility. Hope that this helps, at least with arming you with information as to why it has happened. Basically, you can start in three major areas, ignition, fuel, and unmetered air leaks.I'm converting my S-10 2wd blazer to a 350 engine.use to be a 4.3 TBI eng.?
Take it to Firestone or auto zone and have them hook up the reader to get the codes from the engine and they will tell you in plain english what is wrong and what you need, they will also print it out for you. Whom ever did the emission testing should have told you what was wrong.Where can i find information and advirtisements on cars that run on cooking oil?
Take your car to a service that is ASE. aprooved.That is a legi buiness.The ASE rateing it a while sign.They need to run a diagnostic to find the trouble.Where is the best place in Charlotte, NC for 89 Mazda MX6 engine repair?
It's a 93 so taking it to get codes read won't do anything. The codes on OBD1 cars are so vague that they're almost useless. A fuel injection cleaning and a full tune up may help. If you can find a reputable shop that has a "sniffer" and know how to use it they probably can get the car to pass. Ususally in areas that have emission testing there are shops specializing in this.How much does it cost to repair/replace a transmission?
You may have bad oxygen sensors.. These "Sniff" the exhaust and tell the computer if the engine is running too rich or too lean. High readings of those two gasses indicate a rich (too much fuel) condition. Is your check engine light on? Bad O2 sensors will usually set it off. Your catylitic converter may be burned out as well. You may need another one if the O2 sensors are working fine.Replace O2 sensors ~ $150 - 300
Replace Converter ~ $300 - 400 for unversal fit.. More for OEM (Original Equipment Manufacturer)
First of all, a code check on this particular vehicle will reveal almost nothing. Is the check engine light on? On a newer vehicle a code check tells you a lot, and newer vehicles don't fail emissions without setting codes, but on the 1993 Honda's the computer control system is not that smart. It monitors a few things, but not a lot. To begin with look over the tune up parts, because that is always the first place to start on emissions failures. I don't expect that to be the problem in this case, because you didn't fail for hydrocarbons. On Nox begin with checking egr system & doing high quality fuel injection &/or air induction system cleanings.
