I've done all the basics to prepare for test. (pcv, oil change,oil filter, air filter, fuel filter, spark plugs) Concerning HC's i'm Allowed 100 max at idle. I've had 3 tests now. 1st test on 12/2/09 was 28, i passed that part, but failed functional (check engine light on). I had diagnosis from ford for the check engine light months ago, and it came up that I needed to replace evap puge and sensor kit. I replaced that myself. 2 days after passing emissions and failing fuctional and repairing the functional issue, i failed emissions at idle 146, but passed on functional (12/4/09). Feeling distrust for the place i was having it smoged, i changed my oil and filter again and went somewhere else. I failed again on emissions at idle at 126. I saw the tech throw the exhaust sensor thingy that goes in the tail pipe under the car so he didn't have to reach under. it wasn't even a smooth surface. Couldn't that damage the sensor? My next choice is a diagnosis for $89.00. Should i trust the 2nd place that threw the sensor under the truck from 1 side to the other? and any other suggestions?
