check engine light after Sea Foam
#51
To all the replies
oh yes! You know I never thought of that. And I did replace the brake light switch a few months back but then when the Limp mode started it was parked for like a month and in dec when I got back around to fixing it that’s exactly when my red brake light came on and I couldn’t figure out why. I have replaced the whole master brake cylinder as well. I only poured half can seafoam into oil and other half into the gas (I read the directions and did it then came here and saw everyone saying one can each) but I didn’t really see a lot of black smoke or anything however I was hoping too :-/ but I did see more smoke coming from exhaust than normal and it is windy and cold as heck here so maybe that kept me from seeing Black idk but I drove to the store and it did seem more quiet. But once again getting back in from the store~ turn key~ click~ I was like dang so I put the groceries in and figured I would have to put in N and roll it a bit fwd then start it cause that’s what works but I turned the key and started right up :-( I mean it was good but man I just dk what could be causing that but so other than that~ o2 sensors and figuring out this red brake light, Rover is doing wayyyy better than before when I had been posting asking. Oh wait I do have a new post no one has replied on maybe you guys could help 🤷*♀️ Lol but hmm noticed a missing vacuum hose or so I think. I added photos too so if anyone has the time to check my post out I would really appreciate it!
Thank you all

I would replace the bad O2 sensor, and it sounds like you have a faulty brake light switch possibly, or it needs to be adjusted? The brake light switch is a common faulty part on Discos, I personally haven't had to mess with one yet. Seafoam will not fix an O2 problem.
thanks!
