Ok, so Im runing an OBDI controler for the engine in my truck. It recently started runing poorly and the fuel milage went down the drain. the last time i checked all the codes everything was good to go code 11 for each test. Now Im getting codes 12,41 and 19. The first is an issue controling engine rpm during the fast idle test. the other two are for the lh and rh HEGO sensors. both are reading lean and the left one isnt switching. The drivability issues are as follows. Engine runs poorly untill it reaches 170F. Its veary hard on gas now and wont rev past 4800rpm. I just found that my brake booster is leaking badly and the rh exaust header has a bad leak upstream of the sensor. Anyone have any therorys?
