I passed the CO limit by a decent margin but I'm obviously not burning enough fuel.
I ran the test on mid-grade so 93 V-power alone probably won't get me down the extra 0.24 points.
I've been reading that running injector cleaner helps a lot. Does it matter if I pour it in before I tank up or not? I think not as it would all mix together anyway.
I think its also important to not that over the last 2 weeks or so my idle has been getting rougher.
I was standing in line with my car on and not only would the idle flucuate from 500-750 rpm but the car would shake a little? Could it be knocking?
Thanks in advanced  |
Change
oil
02 sensor
spark plugs
advance timing
if that doesn't work change your cat.
Run your car hard before the test..that helps warm up the cat..and dont turn it off. Dont let the technician turn it off either.
