i got a code 1506 idle overspeed error... and a 171 lean code... thing is, ive replaced the iac and 02 sensors already... ive also heard a dirty maf can be the cause of alot of headaches.... i could see the lean code being caused by that, but a hunting idle decellerating from 50 mph with my foot off the accelerator be caused by a bad maf?.... ive read up on that 1506 and if i remember correctly... something about the secondary or auxialliary air input... i have no idea where or what that is...also just fyi originally i had a total of 8 codes and now im down to these 2 - all the others were evap,egr,and evr codes all of which dissapeared since i rewired part of the harness for the evap system, and repaired the vacumn lines for the charcoal canister, egr and evr.... however even with my best efforts these 2 codes linger around and my emissions is due really soon... any reccomendations?:confused:
