your running lean. which means you have a fuel delivery issue or a vacuum leak. you can search for vacuum
leaks. also check fuel pressure. heres a video on how to search for vacuum leaks. when you did the power balance
test. did you do the coils and the injectors? if not try the injectors.you can use a spray bottle filled with water and squirt
the areasC8-)http://www.youtube.com/watch?v=9CPqbaSgcok vacuum leaks
can you post the codes. you will need to check spark with a tester. I would also look at fuel pressure at the rail
with a fuel gage. heres some videos to help youC8-)http://www.youtube.com/watch?v=FBUYs539 … plpp_video

thanks ill watch the videos. also the codes that it shows are.
1. Too Lean On Bank 1
2. Random/Multiple Cylinder Misfires
3. Misfire Cylinder 1
4. Misfire Cylinder 2
5. Misfire Cylinder 3I also wanted to add that i changed the fuel injectors on cylinder 1 and 4 as when we bought the car those were the cylinders misfiring. I have also checked the igntion coil packs for each cylinder and i have also changed all of the spark plugs and the fuel filter.
ok i done the power balance test and only 2 of the 3 cylinders did not change in rpms the 3rd cylinder did drop in rpms..

You can also ohm out some injectors at room temperature. See if you can find the factory specifications or ohm out a known good one over a suspect one.
However, i dont believe your injectors are your issue.
And the best way of testing the ignition coils is to test them under a load. Its not really worth while trying to ohm those out.
I am with College Man in checking the fuel pressure and checking for vacuum leaks.
Do you have access to a scan tool that shows PID data?
Ok update guys…. First off i want to thank Eric The Car Guy for the youtube videos! They saved my life LOL. I also want to thank College Man And Dreamer. If it wasnt for you three i wouldnt have known where to start looking…. But besides that heres what i hade to fix. 2 Ignition Coils and 1 Injector Plus there was a vacuum leak that i had to fix. Car runs great ive done donuts in it already 😛 for test drive. Thanks again people and i know where im coming to if i need mechanical help again. And i will most definitly refer friends and family to this website if they ever need help like this!!!!
