There are all these vaccum lines and valves and a hidden computer and solenoids and all sorts of stuff that, even to me, is complicated. I have one sitting in the yard, it's a 1500 cc though.

If you have fuel injection, there is a much better chance it will work properly.

 

oh dang yeah im confused alreadyy. im not suree if i got fuel injection?

so doyou think if i get a new cat it still wouldnt pass smog? causee its just got high HC ithnkk,

 

cant think of a good way to explain it, post a pic of the engine

 

 

Yep, that's a carbureted CVCC model. The black box on the firewall with all the vacuum hoses leading to it is some of the complicated stuff.

Post the complete test results. Was the HC high at idle or at road speed? Were the other pollutants close to the legal limit too?

 

yeahh idk how to read it but ill just write exactly how it says:

HC(ppm) : 2369 CO(%) : 0.16 CO2(%): 9.40
O2(%) : 8.57 RPM : 966
----------------------------------------------------
HC(ppm): 932 CO(%): 0.22 CO2(%): 11.20
O2(%) : 5.41 RPM : 2566

 

Reply! Haa im anxtious to whats wrong with my car you been a good help

 

Were the legal limits on the smog report too? So the problem is mostly at idle. Does it idle smoothly? Misfiring is going to put out a lot of HC with O2 staying high and CO staying low. Does the temperature gauge come up to the normal reading of about halfway? You should check the spark timing. Turn the throttle stop screw to reduce idle speed some.

 

Well i know those numbers of ppm are suppose to be under 100? Ha and idk bout the other oness when its at idle its sorta load it doesnt sound real smooth it sorta rattles
