hello,
I checked the fuel pressure regulator by running the engine for a while
revving it up to 3500-4000rpm shut it off
and then pulling off the vacuum hose and smelling it....not wet and did
not smell like gas....so I think it is ok.

I removed the injectors from the intake and turned key to on position and
did not find and leaks.

I changed my oil...just had it changed a week ago dammit....and put on a
new filter, and everything seems to be running ok...took it for a test
drive about 10miles on the highway.   I am guessing that an injector
could have stuck open temporarily, or is leaking intermittently.....I
dont know.

thanks for comments,
