so i just reciently got the p2187 code. the car seems like its running fine but im not sure what to check. The reason i say im not sure what to check next is cause this past march i replaced the pcv hose that cracked and gave me the same code but it made the engine run really rough. So me and my dad were looking at it and drove it again and the car ran horrible and sounded like it was not fireing on one of the cylinders and it wasnt. we had to replace the coil pack and that fixed it. So then we re set the engine light and i made a 8 hour road trip and the next day after getting back the check engine light came back on with the p2187 code on it. What do you think is wrong now. like i said the car seems to be running fine so i dont think my new pcv hose cracked. I was thinking maybe air leak but i havent tested yet or could it be injector related. O ALso the spark plugs have already been replaced when we did the pcv hose.

Check for leaks (pressure check intake system)
Replace purge valve solenoid

What mods do you have? (Sry if their in ur sig, I have sigs off...)

I have the same code.. been chasing it for a while but I'm pretty sure in my case its down to not having my MAF calibrated, as soon as Cobb reopens and they send my accessport ill be able to take care of that.

Oh and try cleaning your MAF. Make sure you use the right spray!

yea im starting to think it might be a air leak in one of the hoses around the air box cause my wife told me that when she went to come home the check engine light was off. So it turned off my itself for some reason. the temps been fluctuating here so i wonder if the warmer air caused the hoses or tubes to expand a little bit and fill in the gaps. im gonna pressure check the hoses. you just use throttle body cleaner right.

Temps going up and down will make it all differ just off of the air volume. When its nicer out my fuel trims settle off relatively well and I have no issue with the CEL but once it gets cold again it comes right back because my ltfts skyrocket...
