Long story short, I installed a S/C and everything went smooth with no CEL whatsoever and running great. Drove the car a few times to put 150 miles on it and no problems, had a shop install some resonators to quiet the car down and when I picked it up the CEL was on and on limp mode (coincidence), I keep a scanner on the car just in case and got the P1209 code(brake booster, vacuum sensor) fault. Replaced the vacuum sensor since its the most common and no dice the code came back after driving back from work yesterday, I’m gonna buy some brake cleaner and spray vacuum hoses to see if I don’t have a leak, but I’m thinking it might just be the vacuum pressure pump itself. Anybody know what the fuse is to check the ELUP ? Any advice ?
