How do you check the IAC valve, what do you look for? Just took a ride and got P0171 (system too lean). I checked all the hosed and made sure all the hose clamps are tight, so shouldn't be a vacuum leak. Before I cleaned the MAF, the car ran fine, although I did get the P0171 after I cleaned and reoiled my air filter. This is why I decided to clean the MAF. I don't know what to do? Could the MAF be messed up now?
