I've tried everything. Not really, but it feels that way.
I got the mysterious p2187 code the other day, "lean at idle". Then i did tons of OCD rearch, and down the rabbit hole i went. I dismantled the car by removing the TMIC, battery, and intake. I looked over all the hoses, cleaned the MAF (which was surprisingly dirty), checked bolts on the throttle body, checked the EGR delete bits, and made sure all sensors were clean. I also removed the Purge Valve Solenoid and tried blowing through it, but it appeared ok.
I didn't find anything except for that dirty MAF and a plug that fell off the throttle body, from the coolant bypass mod. But, that's not a vacuum source anyway, right? Besides I put another on. I reassembled everything making sure to tighten down correctly and started her up. Car was fine for like 5 miles, then the check engine light came on. Same issues.
I went to work today and stopped at Advance Auto for a new Purge Solenoid Valve, since I read most 2187 codes are related to that. I put the new one on and crossed my fingers, nothing. Same issue.
My question now is, could it be an o2 sensor with no codes for that showing up? Is there something I missed? Any insight would be appreciated before i have to succumb to the Mazda dealership overlords.
