Take it to a different place to get it inspected, if there are no codes it should pass this test

SOURCE: my 1990 chevy lumina just started making a noise when aceleratin

change fuel filter.then check fuel pressure.if you got TBI FUEL INJECTION PRESSURE SHOULD BE 26-32 PSI. IF YOU GOT MFI FUEL INJECTION PRESSURE SHOULD BE 40-47 PSI.if all is good .have car scan check the egr valve.map sensor. coolant sensor.if any one of those are bad it causes rich fuel mixture.that will cause you to fail smog test.also replace plugs and wires.if they are faulty they will misfire cause unburn fuel to come out exhaust.also check for for intake leaks check all vacuum hoses.

SOURCE: 97 CAVALIER (Z24) FAILED SMOG TEST

No, the water pump leak would not cause it to fail the smog test. The only way that could have any bearing on the test results, would be if you lost a lot of coolant, and the car was overheating, then maybe it would have something to do with failing. What were the results (specific #;s and exactly what failed?) Is the check engine light on?

SOURCE: Failed CA smog test "MIL/Check Engine Light", computer data wiped

No this is not right. If you remove the battery everything resets anyways. If they are talking about relearn procedure, it should only require 50 miles. But if the light is on than either they did something wrong, created another problem, or there was already another one existing. Have the code read and let me know what it is. I'm in Ca too and used to prep european cars for smog, so I do know what I'm looking for. How did the rest do? What were the readings(if possible)?

How is ignition timing regulated? Car gets 99 BTDC on ignition timing and failed SMOG Test in CA. Listed as GROSS POLLUTER.


something wrong here
with 99 degrees btdc it will not run
have you got it on the correct plug lead
next the timing is regulated by centrifugal advance if electronic or points and by the crankshaft position sensor if ECM controlled ( some after market distributors that are used in place of points units have a small sensor in the distributor that can adjust the timing according to engine rpms, but it cannot make allowances for mixture and so they can advance the timing but not take into account anything else which sometimes results in detonation under certain throttle settings
so initial setting for most cars is 10-12 degrees btdc at idle and with engine rpms set up to 3000 rms it may advance to 25-30 degrees depending on the advance mechanisms
with ECM units the timing is controlled by the crank position sensor and is set to parameters according to engine rpms and air/fuel ratio settings but it still has a basic 10-12 degrees btdc on starting
to fail smog tests you probably do not have a working cat converter and other problems besides timing

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 ?

My car just failed smog emissions test, had high nox count, at 15 miles about double max allowed, at 25 mit iles per hour, triple max allowed. The car is a 91 plymouth voyager.During the test it smoked...


i would put a good tank of gas in the system. like 93 super.drive the car for about 1 week or at least 100 miles. i would also go to a good auto parts store.u should be able to buy a bottle of engine cleaner to pass the smog test.also when u bring the car in for the inspection.take it for a rideand get it nice and warmed up.
