low idle car being really rich
hey guys i recently did a valve adjustment to stock spec, as well as replacing my fuel filter. i also installed the mugen thermo and fan switch. the problem is that now my car runs really rich from cold start to warm up. i check my sparkplugs they are pure black as well as my wideband indicating. my car idles fine at cold when it starts warming up a bit the idle drops, i'd say less than 500rpm. when i give it alittle gas at neutral the car dips all the way to mayb 100-200 rpm and it dies out. when it dies it, it takes time to fire back up. my question is would the mugen thermo/fan causing this problem? or can i adjust anything on my emanage to compensate with the rich area?
