ok so i installed my zex wet nitrous kit yesterday and after everything was complete, i started up and checked for fuel leaks( had a small one, and fixed) but then i got an SES light, today i went to autozone to use their scanner and i have a p0300(random misfire) and a p0113(iat circuit 1 voltage high). and theres a funny noise at start up from what sounds like the starter(almost sounds like its scraping the flywheel). i was wondering if the fuel leaks might have set off the ses light. i basically went through everything to try and solve the problem but im stuck. ive reversed all the modifications ive made and still i have the ses light. i dont know where to go. help
