I got these two codes recently and i know the 0496 is the evap purge solenoid and the 2187 is lean at idle. The car also wont boost past 6psi sometimes Im about to change the purge solenoid but I was wondering if that would cause the 2187 code as well. My mods are dejon SRI megan racing catless DP, mpx catback and forge bpv. no tune as of yet

 

so... you got all that with no tune? not even gms1? I'd say get a tune...

 

Its quite possible the SRI with no tune and the purge solenoid not working is causing fuel trims to skew greatly at idle and everywhere else. The intake could do that all by itself too.

Replace the purge sol. and get a tune for the SRI, or replace the purge sol. and go back to the stock airbox.

 

unplug the purge and see if that helps for now.

 

lmao funny thing is the one time i did this... my car didn't wanna run. Apparently if the lower GMS1 sensor is messed up it goes off the evap solenoid and well my car didn't like it when both weren't working lol

 

How does it run off of the Evap Solenoid? lol

 

^^ yeah?

I unplugged mine this morning and it seems to idle better i guess, but i didnt reset the computer yet. i just gotta go to the dealer and have them fix it.

 

Good question lmao I just thought it was funny that unplugging the evap solenoid made my car worse. I was more being a smart a... tho lol

 

so i changed the purge solenoid (23 bucks from the dealer) and so far so good runs a little better than i recall actually lol so hopefully that fixed
