Help check engine light!! P2187
check engine light randomly came on and then turned off a week later.. same thing happen a couple weeks ago and it turned off again.. and now it’s happening again.. I scanned the car and I’m getting a p2187 code “mixture in the right cylinder bank is too lean when idling”
i also want to note the car came with a renntech intake. I noticed the vacuum hose was disconnected and I reconnected. Would this be the issue?
i reset the code on the car after connecting the vacuum hose.. going to see if the check engine light turns on again
