Took my car to DEQ today and it failed on the total hydrocarbons (THC). They were double what they are supposed to be.
The car has been running a little rich because when I pulled the codes I get "adaptive fuel lean limit reached, rich reading right side" and same for the left side. I also get ACT out of range.
Could the air charge temp sensor be making it run that rich? I cleaned my O2's a couple weeks ago, maybe I need new ones.
Looking at the graph for THC's, they seem to be well within limits when the car revs up but when it goes to an idle they shoot way up. I have been having a problem with the idle dropping below 500 when I come to a stop but then it catches itself and returns to normal idle.
Any ideas?
