P0300//mulitiple misfire

[hawaiih3]

Hello,
Just here for an update on the mulitiple misfire (P0300) that I was dealing with; after about 3 weeks the of running the vehicle with STP (black bottle)(ran a bottle every other fuel tank fill-up) the check engine light has not returned. So, the issue was clocked fuel injectors, I am sure a good high pressure injector cleaning might be helpful as well but the STP bottles helped alot. Initially I ran 2 bottles of that stuff with a half tank helps in getting a less diluted product thru the injectors, no harm will come to your engine, the company also reccomends or at least suggest that it is okay to combine other STP products if so desired. Thanks to all that assisted or advices on my issue.
Have a nice day!
