Hey yall, thanks for all the advice!

I got a new O2 sensor installed, as well as a new fuel filter (my dad had purchased one years back for the car), and it turns out the old fuel filter was bad too. I got a new catalytic converter put on, and new spark plugs. My car doesnt reek of gas anymore, and it cranks faster, which is great, BUT, I noticed it shook really badly when I tried to drive it so I got the guy who put the new parts on for me to check the spark plugs for the gap distance. He gapped them this time, and now the car is shaking even worse and its like the engine is shaking and knocking when I get up to 45 mph. The jeep also shakes horribly when I am idling at a stop sign.

What do I do now?!?!

If the fuel filter was that bad it could point to clogged or sticky fuel injectors.

My 99 was idling rough, difficult to start and was getting bad gas mileage. I replaced the Coolant Temperature Sensor. It fixed all of these things immediatly for $18. It is the sensor on the engine where the radiator hose goes on. The sensor sends information to the computer and alters a bunch of settings for cold or warm starts. Best $18 I have spent on my Jeep. Not sure if this will help though, mine ran Ok at speed.
