I failed the lame MA state emissions test. Everything ran fine my tps is fualty and i know its bad and that is the only code my car is throwing.

The CO grams is the part that i failed my car clocked in at 69 and the limit is 30. I have no idea what would be the best way to fix this. 69 is way over the 30. Some have suggested replace the tps which i already ordered and get a new o2 sensor. Will these two things be enough to get me a pass?

I have some time to get it reinspected but i know the car is running extremely rich and I am just not fully sure how to adjust that. ANy suggestions would be appreciated. by the way this is on an 1987 TII.

 

Are you running a cat.

 

do you have emissions on the car ? full tune up, lean the car out; i really don't know what causes the hydro's and carbon's blah blah...ill let someone else be the advice giver.

 

I am running a cat not to sure of the condition of it but I am running one... also i did just recently change the plugs and oil. I am not sure how to lean the car out though i know it would help a lot in essence but im not sure how to do that

 

also try leaning out the variable resistor as much as possible, and throw in 10 ounces of alcohol if you have a full tank.

 

Almost right below the boost sensor is an adjustment screw that has an l and an r on it. Turn it slowly towards the L and you will hear your idle fall. Keep turning it unless your engine wont run. Drive slow and gingerly to the inspection staion. Im going tomorow to get my 87 t2 inspected and im not running a cat.

 

ok let me know how it works for you... what kinda alcohol should i inject into the tank? I know the exact r/l screw but i believe it only works for idle...

 

and where is the variable resistor and how do i lean that out?

 

Not quite sure as to the alcohol question. I believe the variable resistor is the thing that I talk of in post #6. Not sure though.Ask other gurus as to what and where this variable resistor is. I would love to know as well as you. Afterall, Im in Mass too.
