mrmann

evening lads... recently been working on the old girl (4x4 saph). started her up and ran sweet as a nut for about 5 minutes, then the idle just dropped off too the point the car nearly cuts out then starts idling again. does this every 20/30 seconds... im sending the chip back to msd this week to be recalibrated for the new turbo but i cant imagine the chip that was set up for a T3 would be so different for a T34 at idle
any ideas where to start looking?
cheers
