Hi
I just got my VSC / CEL light this weekend. Now that I read through the posts, I know my first step will be to get the codes and go from there, but looks like common issue is the gas cap, vacuum hose disconnected, or oxygen filter.
All of these are under the hood activities.
However - I have another factor in the mix. Has anyone had these issues supplemented with the car start making noise as if the muffler has a problem, that racing car sound. AND a certain pipe / hose disconnected under the car, in the vicinity of exhaust system. I wasn't able to find too many labeled diagrams yet but the disconnected hose hangs 6 or so inches under the car, right under the driver seat area. the end of it was connected with two screw looking like connectors. The 3 events came within a couple of hours while i was driving:
1) i started to hear the car growling (but knowing i've been having issues with the exhaust / muffler that my dad patched up a couple of times, i ruled out out to yet again having to patch it up)
2) the VSC and Engine lights went on, at which point i pulled over, and after reading on definition of the lights decided to visually unspect the underbelly and saw #3 - the disconnected hose.
Thank you for any help you can give on this. I'm learning to DIY :)
I've been looking for a good diagram of the "underbelly" of Lexus RX300, so I can at least know what parts are what there. If anyone come across anything useful - please share.
