I found out that I had a leaking injector in my 92 sc400. I removed the lower manifold and found that the port where it was leaking from is clogged..i suppose..anyways gasoline is just sitting in that port of the passenger side head. Would it be clogged or just needs to be burned out? Is that also saying i might need a new injector for that particular port or what? Plz help...trying to gain knowledge about the 1uz for future reference.
