Title: P0171 system too lean fault code
Post by: jakex181 on January 25, 2015, 05:46:43 pm

Just had the engine light come on and when read using my torque app it came up with P0171 which is system too lean. Ive recently taken my neuspeed intake off and put the original air box back on, not sure if this is relevant. Any ideas of the cause?

Also as I took off the oil filler neck when I had the neuspeed intake I had to refit it, to do this I glued it back on, if this was leaking could cause this fault?

Ive found that this problem can be caused by a vacuum leek so im going to get some araldyte and re fit the oil filler neck as i only used super glue before. Hopefully this will sort the issue.
