So, the weather turned a bit colder and now I'm getting the codes for banks 1 and 2 being too lean, so I'm guessing there is a small vacuum leak that rears it's head when it gets colder, as the idle tends to fluctuate slightly as well, every once in awhile it's drop below where it should normally idle and feel rough, but very rarely.
So I'm considering doing the smoke method to track down any leaks that there might be, for anyone else that may have done that, which is the best approach to doing that on this car, is there any particular hose you'd recommend using the pump the smoke into that would work best?
Hoping to finally get that issue tracked down, and it seems that's possibly the most likely culprit is a vacuum leak since I'm getting P0171 and 174 lean codes, but only in colder weather, but during the warmer months I wasn't getting the code, but the idle was still fluctuating, so if it's indeed that, it must be very minor and the cold just angers it, lol. Going to pull the ignition coil off this weekend and check the bottom of it to make sure it isn't heat cracked or anything as well, just to rule it out.
But thinking the smoke method is going to be the easier way to find the leak, just need to figure out which hose is the best candidate.
Thanks! And hope everyone is healthy and staying safe!
