My injected 75 2.0L has been running like crap for the past few months. I replaced all the usual ignition parts, all fuel lines, gas tank, and fuel pump(had a spare). Still ran like crap. Every time I made a hard turn it stumbled for a few seconds, then ran fine. Made a trip to Okla City today and didn't think I was going to make it back. Just wouldn't go over 4K. Joseph222 asked about the filter and a light came on. 3 minutes to change it, and now she screams. When I took the filter off, I held it so the outlet side pointed down and no gas ran out. Turned it over and gas ran out along with 2 tablespoons of rust from the previous gas tank. The high pressure of the FI pump was the only thing keeping gas to the engine. I am amazed at the difference in the way the car runs now.
CHANGE YOUR FILTERS REGULARLY. Especially if you store the car for the winter. I know I will from now on.
Thanks Joseph.
