Went to get a smog check and i failed because apparently my carbon levels were to high. Does anyone know how i can fix this?
They tried to charge me an extra $70 on top of what i had already paid to have them tell me what's wrong with it "diagnostic". If it matters, its a honda civic 90
Guess what? That $70 diagnostic was probably a bargain compared to what it will cost you to diagnose the problem now. We can't tell you how to fix it without knowing the problem. You can't learn the problem without diagnosing it. Since you obviously lack the skills and knowledge and tools, then you'll have to pay a shop to diagnose it for you, and it's likely to cost more than $70 to find out what needs fixing. Sorry.
When the fuel tank is almost empty, try some fuel system cleaner (Techron, Gumout, or Seafoam) and then drive it on the freeway for about 40 minutes.
Get the plugs, wires, air filter and fuel filter replaced. Get the timing checked. Drive for an hour at freeway speeds before getting it smogged. Let the engine idle if you have to wait at the smog station.
Your car is old. If it still does not pass. It is time to sell the car and let the new owner fix it. Car might need a new engine.
There are 4 "carbon" concentrations on a smog report: high and low speed levels of carbon monoxide and of carbon dioxide. Carbon dioxide can't be too high; low carbon dioxide (CO2) means an exhaust leak large enough to let the exhaust be diluted with air; that is a job for a muffler shop. Carbon monoxide (CO) is produced when the fuel burns with too little air, it is a "mixture" problem that will need a mechanic to correct.
In general, emissions problems are not DIY affairs even for moderately experienced amateurs. It is hard to do anything meaningful without special and expensive equipment. I do my own just because I'm stubborn and have made a good living troubleshooting things that I have to fix, whether we have the right equipment or not.
A tune up and a new cat converter should fix it
A 1990 Civic will probably need a new catalytic converter if it's never had one and new oxygen sensor couldn't hurt either. With these two items you'd likely pass.
- Is the reason why a motorbike engine won't work in a car because they can't produce high torque at low RPM? I have a 1.3 litre Mitsubishi Colt. Maximum power output 94 BHP at 6000 rpm Maximum torque 92 FT/LB at 4000 rpm Honda 2017 CBR1000RR 1 litre Maximum Power output 189 HP at 13,000 RPM 85.6 FT/LB at 11,000rpm
- I was looking at q a 2003 Honda 750 ACE because it has low miles. But I was wondering about what I should look at because of that? It's 14 years old and only has 1,900 miles on it. That means it's more than likely been sitting a while. I haven't messaged the person about it yet but I was just wondering what I should look for if I did go and look at the bike? Any suggestions?
- I have a Honda timing light part # 0132-99908. Does anyone know how it works? Motocrazy? I have a Honda timing light part # 0132-99908. Does anyone know how it works? It has a 120v plug on it, does it plug in the wall outlet or another Honda instrument? If so do you know what that item that it plugs into look like, part # etc. Thanks, Motocrazy This is a vintage timing light.
- Does anyone in Colorado know any cheap ways to get a catalytic converter/manifold exhaust leak repair? I took my car into Goodyear today and found out I have a manifold exhaust leak and that I need a new catalytic converter. I drive a 2001 Honda Civic LX and am incredibly inexperienced with cars. The price estimate was $883.37 and I was wondering if anyone in Colorado Springs know of a mechanic that will do the repairs cheaper or a mechanic that will install maybe an aftermarket cat converter? If I looked for aftermarket converters, what would I need?!
