CHEVY EGR

1994 Chevrolet Beretta

Shakes or Wobbles problem
1994 Chevy Beretta 6 cyl Front Wheel Drive Automatic 257, 00 miles

i have a 1994 beretta that I bought back in june and it had basicly sat for a year not drivin. It was really ruff driving when I got it and thought it was because it sat for so long. When I didnt go away I looked into repairs. It used to die while driving, shacks all the time, has no horsepower, and vary vary poor gas mileage. I replaced the O2 sensor and that fixed the dying part of the problems. I had the car checked out and was told to replace the EGR valve so I did and it drove great. For 3 days and now it is still shaking really badly and still has no power and still gets bad gas millage. I noticed it does not have a Catalytic Converter as well and im wondering if that is the reason for all this too. The EGR valve seems to be all gunked up when I take it off to clean it every time and this last time I cleaned as much as I could of the valve, hose, and whatever else it was connected to that I could get to with a toothbrush untill I was getting nothing but clear cleaner back and not build up. My question is, is there something else I should be looking into to fix this car or something else I should be cleaning to get this buildup gone? I thought maybe the vacuum line was clogged or dirty but dont know how to clean that either.

The converter can play a big role in this problem. If it isn't there, the computer isn't receiving the right info from the O2 sensor and it's required by law to be on and functioning. Also, did you replace the EGR or just clean it? Are you sure the valve is sealing? Finally, have you checked closely for vacuum leaks?

Let me know.

I have bought a new EGR and put it on. I have no idea if its sealing I mean I tightened it as much as I could and I dont really know how to check for leaks. Someone else had told me to replace my spark plugs and I dont know how that is suppost to work. Also we had a big snow storm here recently and scence then the car runs great. It seems that now that its really cold the car runs fine but after a while it starts acting up if driven to long.
