The first thing you need to do is check to see what codes you have with the engine light. If you don't know how, this will help; http://www.lexls.com/tutorials/intro/codereading.html
Also need a bit more info. Did the car sit for a while after you did the work mentioned or did you just do the work now and it started to run like crap? Ya need to figure out if it's fuel/air or spark related. Check for spark at all 8 plugs, ya might find you have a bad plug wire or coil. It could be something as simple as a clogged fuel filter, or it could be something alot worse. Gotta check for the codes first and go from there.

Thanks for the responce.. The car sat for about 10/m then replaced the manifold and cats and it ran ok then 2days later it was loke crap so I changed the pulgs and gas filter and now it will not start and when I turn the key on the dash light dose not come on. After trying for awhile the dash will light up. Now when it do get started it's like 1/2 of the car is on. Thanks again for the link I know it's going to come in handy and I'm going to get the codes....
