Hey guys I need some help.
I have CEL code P0170 being thrown on my 2001 Evo 7. I assume that this code is the JDM equivilant to P0171: lean. Is that correct?
The funny thing is that when cleared it stays off during normal driving. Then when out on the highway, after about 20 minutes at 80mph it will pop right back on. This last time that i pulled it, the scanner said it happened at 78mph under 25% engine load. I cleaned my mass air once should i do it again? what else could it be????
I really need it taken care of so any ideas would be helpful!
PS i have searched the topic
