It needs to go to a shop. If its emission related the longer you wait the more damage you'll do to the catalytic converter. Then things get expensive

Why can't I pass smog check engine light won't come on


The smog check requires a visual inspection of your check engine light. It has to come on for a bulb check at startup to make sure it's working. But, the light must go out after starting the engine(it cannot stay on after the engine starts during a smog check). If the check engine light fails either of these two tests, the vehicle will fail the smog check inspection.
You need to have the cause of your inoperative check engine light diagnosed and repaired.

MIL/Check Engine Light will not come on during start up to pass smog 2000 Ford Mustang


There should be a 10amp fuse in the fuse box for the instrument panel that powers the light. The light is grounded by the computer.
Have you checked the fuses in the passenger compartment ?

The person running the test is an idiot. The OBDII test instrument is not capable of determining if there is a warning lamp failure. It is probably guessing based on voltage level, but lamp resistance does normally vary. The test is supposed to be done visually. Take it to someone else, and they will probably be more competent and pass your car.

Hello
Does the light ever come on while you are driving the vehicle? It is possible that the vehicle does not trigger the code on the key cycle when vehicle is connected to the OBDII scan tool (a cycle is the time from when a vehicle is started to the time the vehicle is turned off) you should however most of the time be able to check a vehicles trouble code history to see what may be turning the light on
Good luck

My car won't pass smog because the engine light won't go off. Is that possible? What does the engine have to do with smog? It's a 2002 Corolla


Smog is what comes out of the tail pipe. Have the engine checked out as to why the light is on, and have it fixed. .

Engine is doging down with muffler off no hollowed cat timing perfect


Your description is not very clear to me, but your engine, in absence of modifications, REQUIRES the back pressure provided by cat and muffler.

Gone are the olden days of disabling or removing some smog device and engine runs better. Your vehicle is designed from the tip of the air filter intake, to the tip of the exhaust, to perform its' best. Remove anything and suffer performance loss, usually. You need to recam, and make other major midifications to be able to remove cat.

You will never pass emission tests without everything on and functioning.

Is there a honey comb baffle in my system ,if so can i chissle it out with out many problems and will it increasr the power i dont have...she is gitless


Cold air intake and straight pipe. Baffle would be a smog pipe. Looks like long bullet pipe. I would just use this and no muffler. Or get turbo muffler, and no cat or no smog.

Failed smog, running very rich. changed plugs, cap rotor, wires, tps sensor, map sensor, egr valve cleaned, Has problem keeping stable ide. all over the place. Any ideas


I've seen two cases recently where it was bad distributors causing rough idle. An honorable muffler shop (not a big chain) will test your catalytic converter for free. Is a '91 throttle body? Do Fords have cold start valve or injector? This can cause rich reading if malfunctioning. Anything controlling fuel delivery into engine can malfunction sending extra fuel. When you find problem; do you know clean oil will help pass smog test?
