Did a run with a few Lamborghini’s and Ferraris on Sunday - car went well as I kept up with the fellow Italians - whereafter we went for breakfast.

However, on our way home, the amber CEL came on, but the car was still smooth with no misfires or hesitation. Upon checking with an OBD reader the following codes were shown:

1. P2177 System too lean off idle bank 1
2, P2179 System too lean off idle bank 2

The car starts with no problems, drives smooth with no hesitation or change in performance.

Just to add that it was the first decent run for quite some time not sure if that could have anything to do with it. I always use premium fuel (95)

Will appreciate some pointers as to what I should look at


Thanks

You need to check for vacuum leaks..Any kind of hoses etc. that could get unhooked on the intake manifold...Jason

Some feedback - my sons used the iCarsoft diagnostic tool (I bought it a few years ago for the Landrovers) to reset the Maserati’s CEL.

Since then the CEL has, touch wood, not return.

Hey Jason I tried but couldn’t send you message, can you please send me a PM so maybe I can reply it ?

 

[Jason@ Enzo`s Atlanta]

No, I don't want people sending me PMs unless it's my customers...I pointed you in the right direction...I don't offer step by step diagnosis for every vehicle...Jason

I could come to your place and be your costumer ofcourse but the problem is I'm in another country 🙂 I already tried a lot of things to find out what's the problem, I don't think and want a step by step diagnose, because I already tried all possible things and just need an advice from you as a guru of maserati 🙂

 

[Jason@ Enzo`s Atlanta]

Then tell me what you have done so far?
