Dripping Fuel Injector: Surges at startup and blows fuel out exhaust 850

posted by  someone claiming to be N41EF on  Sat Jan 8 14:17 CST 2005 [RELATED]

1995 855 GLT NA. When I first start the car in the morning, the RPM surges up, and the car blows what I believe is gas out the exhaust leaving a black "sneeze trail" on my garage floor. Gas millage seems normal, about 22.8 around town consistantly. My gut feeling is that I have an injector that has a piece of something in it that isn't letting it shut completely, and as the car sits over night it's flooding a cylinder. So, tonight I bought new o-rings, and pulled the injector rail. I didn't turn the car on, but I noticed that the injector for number one has a much darker tip than the rest. Specifically, there is what looks like a melamine washer on the injector tip, all of them were a "melamine" color except number one which was blackened.

Does that make sence? Anyone else has a problem like this?

Any way to test injectors besides running the fuel pump with the injectors pulled out of the intake?

Is there any place you can send a set of injectors to have them checked, cleaned, flushed?

Or, should I just buy a new injector and swap one at a time?

Thanks, Chuck.
