| Zero4488 | Jun 18, 2007 06:48 PM | I've Run Out Of Ideas.... Alright...ever since I got my car back from getting the clutch and gears put in I've been getting these 4 codes comming back frequently....and I don't know what to do...the codes are P0135, P0155, P0171, and P0174. Two of those codes are "heater malfunction" and the other two are "too lean"....anyone have a solution to my problem? Bad O2's? I am running the diablo programmer and I eliminated my rear o2's but no clue why these codes are comming up....please help.... |
