Not sure if this is an intake question, or a general maint & repair question (I apologize in advance if I have posted in the wrong Forum).
Anyway, I have a 2005 Elise, approx 40K miles wuth a TurboXS after market intake. I have had the car for just over a year and do most of my own maint. The other week the engine light came and after getting a scan of the OBD code I found that it was reporting P0171 (Mixture too lean).
I tried cleaning and re-oiling the K&N filter on the intake and then sort of cleaning the MAF (I inspected it and blew off any dust - it looked very clean). I cleared the code and ran the car for about 15 mins on my driveway and the light stayed off. However, once i backed it off my drive the light came back on (same code) immediately.
I am planning on cleaning the MAF completely (using some brake fluid), but wanted to get some additional input regarding whatelse to try. Also does any one know a viable way of testing the MAF to know if it is damaged (I dont want to spring for a $150 sensor if the problem is elsewhere).
Also I have a track day scheduled for this Friday and dont want to run if the engine is truely running lean - any thoughts on this?
TIA
