SC400 Code 25 Lean Air-Fuel-Mixture
Hey guys, I got a code 25 on my 92 SC400, the car drives absolutely amazing. No hiccups or anything, I cleared the code and it took a good day and a half and about 100 miles later. I'm going to check the intake and vacuum lines for a leak. Hope fully its just a vacuum leak but it might be time to remove the injectors and clean them and do fuel filter replacement. I just dont understand because the car runs amazing. The car was running hot at idle when I got it but I burped the system and it doesnt overheat now.

Ok, expensive O2 sensors . Probably why my MPG isnt so hot. I just need to replace upstream right. Downstream is just verifying the cats?
I'm going to try to pull the injectors and clean them.
