so i have a 2003 c32 amg with 215k miles and i just bought the car last thursday had a coolant leak then fixed it then a check engine came on wasn’t too worried ab it bc i saw zero difference in performance of anything then today i went on a cruise got a weird fluid sign on the dash but i couldn’t read it only could tell it said at station with an oil sign then i kept going later on i saw the car smoking checked the tempt i was fine i stopped messed with my maf sensor put it back and then the problem began where the rpm’s would go up but the car wouldn’t accelerate as it should it’s not in limp mode bc eventually i could get to 90 but it takes a lot longer than usual please help
