Alright, so wtflip. Driving a crx w/b16a3 (<---lemme know if more info is needed) When it's night time or its like somewhat chilly and rainy car drives pretty good, however it can get a little more lean than I would prefer--oh well. But when the sun is beating down on it, fuel goes way rich and be-bops all over my indicator and smells...ugh. Planning on installing hondata asap - will this clear up the problem? I can't figure it out, could it be the air temp sensor? Sigh...I'm sick of watching the weather to see what my mileage is going to be for the week.
