I used "Sea Foam" this weekend following the directions During the process the SES light came on. Took the car out for a short drive to get rid of the residual "Seafoam" car runs great but two codes presented #1=PO300 (Random/ multiple cylinder misfire detected I sorta expected this one. #2=PO336 Crankshaft position sensor "A" circuit Range/ performance. I cleared both codes. On Tuesday I dorve to work car sat all day as soon as I started it in the evening the "SES" light came back on It was the PO336 code I cleared the code and tonite the same thing again. The car seems to run great...So did I break something...Should I keep clearing the code ..or take the car out for a long drive to let the computer re-learn (its only 10 min and 8 miles to work) Any advise Please
Sorry about this being so long But I figured that the more info the better
Thanks Bob

You probably got water in the Crank position sensor connector. Unlplug it, dry out the water and try it again. It wont help to keep driving it, most likely. Either that , or it just went bad at the same time by coincidence, but I doubt it. Good luck!

What is 'Sea Foam' Posted by Corvettekid82 (Member # 1421) on :
Sea Foam is a cleaner comparable to 'GM Top Engine Cleaner'. They are supposed to clean carbon built up and other gunk.
