So dumb *** here decided to pressure wash the GS300 (engine) today Now have check engine light (PO303) ,VSC light is on VSC off light is on . I took apart every connector I cound to look for water and found none.Really didn't hit it that hard with the water! Runs like **** !
HELP !!

 

I'm assuming you sprayed the engine? Just let it dry and see what happens. Maybe even disconnect the battery to reset. Its probably nothing, dumb ***

 

Jokster,
Thanks for the reply
I tryed getting it warm no help ,took the battery cables off toched them togeather but lights came back on. Don't really want to drive it now as not to puke a converter----

 

Its just a guess that the vsc lights are only only because its part of "limp mode" due to the misfire. I'd focus on the misfire. Check and see if somehow water got into the air/fuel system. check around injectors, check in the air box and the spark plugs. The only places i can think of that water could get in.

 

Dont know why you touched the cables together, good way to fry something with the charge stored ANYwhere in the car. Did you keep them off for a good 15-30 mins? (I think it usually takes like 5 to reset, the more the better)

 

I will take them off and let it sit for a while, I took the covers off the top end to check plugs etc. but all is dry there.... Like I said I just gave it a quick spray... OK on limp mode that is what I suspected..
Thanks again
Norm

 

Lol in the future use simple green it's an easy way to clean the engine bay

 

Just for fun, check your ABS computer up on the top driver side corner by the windshield. Small possibility that a little water got in those plugs, however if that were the case, I think you'd get that buzzing from there. Doesnt hurt to check though.

 

Just let it dry out. Leave the battery disconnected for a while. You should be fine.

 

Checked the ABS and every plug I could get apart & left the cables off long enough to have to reset the seats . Still missfireing badly. Guess I'll let it set overnight & hope for better things in the AM. Looks like the motorcycle may be a option for Mon.AM commute but Burrrrrrrr

 

Lexo98,
I hope so ,I really went over everything again tonight.I'll leave the battery cables off and hope for the best on Easter morning. Meanwhile I'm charging the motorcycle battery. Low 30s Mon Am on a motorcycle will be a eye opener !
Thanks again for the help & will keep you posted

did the muffler bearing get wet? that may be it

 

Maybe even disconnect the battery to reset.

 

If you were to even read any part of this thread, the OP already tried that...

 

Made me lol
