Last Friday I was trapped in traffic behind an accident for about an hour. Temp got up to about 230 or so and would cool back down with the fan kicking in. Got home, no problem. Saturday started the car and it would not keep running. Spitting and backfiring. Yesterday it acted better at first and then, once away from home, it came back with a vengeance. It threw the first code in over a year. Code 32 for the EGR - found a disconnected vacuum line at right rear of intake, put back in place and code is gone. Noticed brake fluid leaking at master cylinder/ booster connection - could this create a substantial vacuum leak at this site? Replaced the plugs and put in 160 thermostat. A little better if you put your foot in it. Fuel pressure is 44 with igniton on, 40 with engine running and drops to 10 within 3 seconds of shutting car off. I know that I need injectors, but can they cause the cat to clog up and effect the performance this badly? Oh yeah, very loud metal rattle heard out right side once car gets hot as of yesterday, sounds like rusted out muffler (cat back exhaust is two years old). It ran this way when I bought it and didn't straighten out until I replaced the ECM. Don't want to do that on a hunch yet, though. All this trouble seems to relate back to my long wait on I95. Any ideas?

Thanks in advance,
Scott
