are smog test supposed to make you nervous?
holy crap! took my 10 year old pickup in to get smogged. i got cocky and simply drove the rig around the corner, no warmup. hell, i do meticulous maintenence. fresh oil, fresh mini tuneup....it felt like i was at the principles office! i barely passed! HC was 47, with max allowable 50! i am thinking my O2 sensor, or cat is on the way out. motor only has 47k miles, but the exhaust system has 100k. two years to ponder my next move...
what bumps up HC?
