Chips and obd codes.

I recently bought a 99 plate 156 2.5 v6, on looking through the paperwork it had an Autodelta performance chip fitted in 2002 (price of chip then £319.50 ) what effect would this have on diagnostics? When plugging fiatecuscan to the car it is throwing up lambda, cam position and maf sensor faults, (although the car is runing OK, goes like stink ) is this to be expected of do I need to delve deeper into it?

I think, you should check your timing, CAM position is usualyy altered by bad installation of timing belt.

Cheers Sarkan, that was on my to do list. The belts were done 3000 miles ago, but there is some tipex marks on the cam covers
