It depends which emission you are failing on but I suspect that it is either CO or NOx. If it is NOx, then it is quite possible that you have a problem with your EGR valve or the ignition timing is incorrect. If you failed CO, you may have a dirty air filter or indeed, a bad carb, but I would need to know the actual gas and readings to be certain.

Could be lots of things.
It could have a leaky injector that is dripping all the time.
You can pull the injectors while still on the fuel lines, to see.
You could have bad compression and burning oil.
You need to do a compression test to tell.
You could have a bad plug or wire.
They are cheap to so just change them.
The fuel injection system could be off.
Check the temp sensor, air mass sensor, O2 sensor, with an ohmmeter.
Don't remember the values, but bad ones usually go 0 or infinite.

IF DECELERATION FUEL REDUCTION SYSTEM IS NOT OPERATING, FUEL ECONOMY WILL BE REDUCED WHILE HC AND CO EMISSIONS ARE INCREASD.SEE ON MANY ENGINES WITH DECELERATION FUEL REDUCTION SYSTEMS THE PCM STOPS GROUNDING THE INJECTORS IN A SPECIFIC RPM, DURING DECELERATION.

P1412 = Secondary Air Injection System Malfunction (Bank 1)
This is from the EOBD section of the manual.
From the SAI section:
If the vacuum operated SAI control valves malfunction, the following fault codes may be stored in
the ECM diagnostic memory, which can be retrieved using ’Testbook’:
P1412 is one of these, particulary described as : SAI system fault (LH side) - air delivery not reaching catalysts.
(DS note. The Left Hand side is as viewed from the drivers seat, not from the front of the enngine bay looking backwards!).
The above system faults could be attributable to anything which might prevent air delivery to the exhaust manifolds (e.g. disconnected or blocked SAI delivery pipe, disconnected or blocked vacuum pipe etc.)

The car runs fine, it must have been a really cold start for this to come up.


P1415 = Secondary Air System, Bank 2, Drive Cycle D: Signal. Land Rover CD lists P1415 as being the result of a disconnected or blocked SAI delivery pipe, diconnected or blocked vacuum pipe, etc.......

Service engine light on-won't pass smog test


You will need to plug in a OBD reader first and run a diagnostic check. Without this we can only guess at what may or may not be wrong with it.

Won't pass smog, Rich idle.


First, is the check engine light on ?
You should have a code for the O2 sensor showing the exhaust gas is rich.
Could be a faulty injector, fuel pressure regulator, or O2 sensor.
Even a faulty thermostat would do it.

My 97 Sonoma will not pass smog


You & we need to know what it failed for

What Emission Gas & what are your State limits
& what did your vehicle read?

You can study exhaust gases on the internet & see
what area of the vehicle needs work based on the gas
readings

Have to educate yourself

Do not wait for someone to tell you things

You won't learn or remember if you don't
study on your own or don't start a binder &
take notes & copy web site info,punch the holes
& put in the binder

Then you take your info out to the car & make the
tests & fix things

Why can't I pull trouble codes for my 1994 Buick


You need a specific adapter to scan your trouble codes. Vehicles prior to 1996 use OBD1 scanners, which are very expensive. Your best bet is to call around a few shops in your area and ask what they would charge to diagnose the code. It sounds like you may have more than 1 problem. The emissions could be due to a bad oxygen sensor and acceleration problem may be due to bad plugs, plug wires, clogged fuel filter, rotor and distributor cap, etc. Do a tune up on it, then see where you stand. At least you won't have to pay a shop to do it if that fixes your acceleration problem.
