You are going to have to take it to a shop so they can calibrate the idle, there's two screws you have to mess with and it's not worthy to try to do it yourself, it'd be very frustrating, sorry. It happened to me and it took me months to finally give up, I paid only $60.

O2 sensor helped me but not enough to pass. Loosen your distributor bolts, one on each side, turn your distributor counter clock wise about 1/4 inch and tighten bolts. This will raise your CO but should reduce the NOX. When the vehicle is passed, undo the changes.

How about the pick up coil in the distributor? A trick we used to use back in the day was to tap the distributor housing with a hammer, key word tap. If the engine missed or stalled than the pick-up coil was replaced.

I just failed my emissions test due to "High HC"

The simplest thing you could do is inspect the connectors to the sensors. You can also try cleaning the intake and the sensors using carb cleaners or tuner cleaner. Check also for vacuum hoses that may have gone bad or could be loose.

Vehicle inspection, pass primary emissions test but failed high idle test HC ppm 559. standard is 220. man at inspection said was missing at high idle,what can cause that??

First either replace or clean the idle air control valve.You can clean it with a non-chlronated brake cleaner and wire brush.Then take the mass air flow sensor off and do the same but don't use a brush just the cleaner only.

Failed Smog Test - 4 codes for 2001 Isuzu Rodeo

Tune it up and replace the 02 sensor that keeps setting the codes bank 2 sensor 1. Have your oil and filter changed right before you go for a retest to. That will clear up 3 codes P0300, 0155 and 0154. You might have to replace the fuel sending unit to get rid of P0463 but if the gauge works OK I'd leave it alone.
