Happy Sunday fellow Zilvians. :wan:
About a week ago my S13 failed emissions. In an effort to save time before trying to replace any expensive components(IACV, TPS etc.) i've narrowed down the list of possible culprits:
-Spark plugs (Checked #1, gap at ".51.)
-Spark wires (Ohms are at about 8.5)
-PCV hose (Coming from the head cover to intake; it's cracked and leaking oil)
I'm also concerned with an idle problem i had during the summer(Well still have actually, but it was more of a problem back then.). Whenever i would turn my A/C on my car would either drop below 500 RPM or just totally die when i let go the gas to stop at red light or just stop in general. I adjusted the throttle cable to set my idle at about 1,000. This was just a temporary solution so i wouldn't die of dehydration in the Arizona heat, i went to emissions like this though. Any chance this could make my car fail emissions?
The other thing is i tried readjusting the cable back to normal but now it won't go back! I start the car(I have to gas it sometime so it won't stall, any input on this?), and it idles normal at 700 but when i gas it and let go it never drops down under 900-1100.
I was thinking of cleaning the throttle plate and maybe changing the IACV and/or TPS but it's kind of an expensive solution to start with.
Am i on the right path to pass emissions? Any help would be awesome i need to pass because i'm running on 30 day tags and this is my DD!!
If i remember i failed the load and idle Hydro Carbon test and the load Carbon Monoxide test. I passed the idle Carbon Monoxide test.
