Could be a mass air flow sensor problem, or a manifold pressure sensor problem. may have several major vacumn leaks that are used to sense and control fuel injection supply pressure and fuel flow. Might check manifold pressure. Check vacumn. inspect lines. there are several lines on air flow inlet. there are several vacumn control valves also. Would suggest obtaining an emmisions line chart. There is usually a decal showing the hose routing on the vehicle some where in the engine compartment.

2000 Toyota Echo coupe sure to pass smog all spec's and testing


You probably already learned that you should have taken it to a reputable repair shop. Whenever a vehicle wont pass emissions, don't try and fixing it yourself, take it to the dealer and let them use the skills and tools they paid thousands of dollars for just to help you get your car back on the road.

Why does my car **** and hesitate and has failed smog 2X is now a gross polluter ?


Because you failed to have a shop look at the data
& make the required repairs & get caught up on preventative
maintenance BEFORE you went to inspection

If you were in fact at a shop, for any reason,then they have no idea
how to test vehicle

Have you considered the motor is shot & you have leaking valves?

Where is the egr valve located on a 1990 mitsubishi 3.0L?


Notice in the emissions part of the service manual. That is has different versions of this truck Canada, 49 state and a 50 state. Not all of them have the egr valve. Some may not have this and in some areas this could cause the truck to fail "NO/PPM" (NOX) on the smog like in LA County. Causing the truck to be viewed as a gross polluter. This reading might be more then double the gross polluter limit allowed.

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.

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.
