Hey i was wondering if anyone knew any tricks to lower my idle emissions on a 95 civic d15 vtec? The required idle emissions it 1.2 @ and idle of 930rpms i ran a 1.25 so i was off 0.05 not much but enough to keep me from receiving tags.

 

o2 sensor? seafoam?

 

Yea im currently running the seafoam. The engine is in my 88 crx and i replaced the stock exhaust manifold with an after market header. But i would imagine a point 0.05 emissions is so minuet that some small mechanical adjustment or fuel treatment would fix my problem...????

 

Oil change, spark plugs...minor tune up

 

your only working with 1.2 anyway. It's already a small number.

 

true, true, i was thinking possible spark plugs maybe get some replacement NGK's and set the gap that should shave a little carbon. The o2 is fine recently replaced and yes it was properly installed. However it has been a while since the last oil change.....

 

plugs, cap, rotor, air filter, change oil and run a can of BG 44K through it (drive it hard). Use dealer parts.

 

Sweet thanks! Im going to try running alcohol and change out my plugs. I have already used some seafoam.

 

Oil & filter, plus air filter will most likely do it if you haven't changed any of them in a while. If you have a stock air filter, you can always try to run without an air filter but I wouldn't recommend it if there is any dust etc. around.
