i got and installed a RRM piggyback last night and im pretty postive its all hooked up correctly its version 2 . ive drivin it for atleast 40miles and let it learn the way it was supposed to. but it still doesnt idle very well and stalls sometimes comin to a stop. i have a check engine light on but it was on before the install. the code is po446 . does that code make the computer go into limp mode cause i noticed when the light first came on that it seemed like i lost power some and now with the piggy hooked up i dont notice a difference in power at all.. does anyone know whats wrong or how to fix the engine code. all i did to fix the engine code is replace my gas cap lid for it so far. thanks

 

if my 02 sensor was bad would it cause this? also how can i check to see if it is ok (my 02 sensor)

 

P0446: Evaporative Emission control system Vent control circuit

 

Doesnt that mean your gas cap is off? LoL check that...and recheck it. then possibly reset your battery. which will reset the piggyback. you will have to let it relearn. But if then you still have a problem its something else. i would unhook the piggy repeat the process. if it doesnt fix it then...! its not the piggy

 

i bought a new gas cap and didnt work.. i unhooked to battery and that didnt work... im unhooked the piggy and that made it run normal . but i still get that p0446 code for the evap still someone said its a vaccume switching valve . is that in the back by the big black battery box lookin thing?

 

if anyone wantes to buy it they can. id post in the for sale section but i cant.
