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.

There is a relative flow test you can run withthe help of a special tool you can buy from an OTC tool dealer. It s a device that plugs into your individual injectors. This test should be run on a bench with regulated FIXED air pressure. You monitor the air pressure running into the fuel rail, first insure there are no leaks. if so fix those first. Next, plug the device into the injector, and shut the air off so that the rail holds the fixed pressure. Activating the device will pulse the injector a fixed amount and dispurse a fixed amount of air thus dropping the pressure in the rail a fixed amount. Record the pressure drop. Next fill the rail again withthe same pressure as before and go to the next injector. Repeat this process for all 5...If they are all fine, they will have dropped the same pressure, if the results are off, the one the greatest offset is the suspect injector.

Hope this helps,
