Replacing the alternator has worked for some, but not in your case I guess. Maybe the replacement was bad too. [img]style_emoticons/<#EMO_DIR#>/dunno.gif[/img]

Heres one for the numbers gurus......Had my car custom SCT-2 tuned after I had the C&L and 4.10 gears installed. That was about 6 months ago. Now I am getting p2106 and 2135 DTCs. [img]style_emoticons/<#EMO_DIR#>/banghead.gif[/img] Think its the A/F that has gone out of wack. Will over reving or anything else cause the A/F ratio to change? Going to the tuner tommorrow. Also just got my Steeda pulley and my Meziere electric water pump from Brenspeed. [img]style_emoticons/<#EMO_DIR#>/04.gif[/img] Next week will be the Dynatech LTs and cats. If Im not careful, my car might go into shock from "mod overload"
