High CO in my 90 Accord
 

:mad: hello, just looking for some help. I drive a 90 accord ex 2.2L. I have taken the emissions test like 6 times. It keeps reading a high CO output about 5.02. thats very high. Things I've done: new O2 sensor, New EGR valve, New Catalytic converter, new Enigine Coolant Temp sensor, new spark plugs, new fuel injectors, new intake manifold gasket, header gasket, and seafoam. Now it runs poorly. When im driving it and want to accelerate sometimes it just won't go at all, and if i let my foot off the gas and accelerate again it works

Hey welcome here.Its a very good and helpful forum.i am sure you'll get lots of information from this forum.

Welcome in ,hope some one can help you,we don't have emmissions test here in Ga. so I have no ideas.

When you made all your changes did you make modifications to your changes?

what do you mean modifications?

have you cleaned out the idle control valve/throttle area. clean air filter. pvc vlv, no collapsed vaccum lines.

yes, I actually replaced the iacv, intake manifold gasket, just replaced MAP sensor as well. I'm going to replace TPS sensor as soon as it arrives. Do you know if i have to adjust anything whe replacing the MAP sensor, i was told to just hook up vaccum line, electrical plug and reset ecu. thanks for any help

Good luck,let us know how it works out.

No you dont make any adjustments on the MAP sensor. The computer on the vehicle makes the adjustments itself when you disconnect the battery. The main parts on your car should take away the high CO.

ok thanks, now i just cleaned the whole throttle body with throttle body cleaner, put on the new TPS (throttle position sensor), and also replaced the fuel filter. It seems to be running way better, no bogging or hesitation at all. I just drove it for a goof 15 minutes. Should i drive it around for a couple days or just take the emission test now?
