Outer Limits 4x4 Board

Searched ? yes I did.

A friend has such a vehicle and it has a problem.

He runs it on gas, and the check engine light shows constantly. The car has been back to the gas system installer and back to Nissan ( I believe)

They all think this is ok.......

The car runs fine, sluggish at the start (friend can't drive ????)

Anyone here have info I could pass on ??

Adding to above, this car is used way below the manufacturers specs.

It is purely a practical number of seats/arses in that family.

The light thing is concerning (to him) because it may mask other issues
