My car is running soooo bad

[cobra2798]

My car seems to have lost alot of power. The car sounds horrible and just put puts along like its running on 6 cylinders. I changed the plugs and even though they were pretty bad there is still no difference. The car ran so strong and now it runs like ass. What other things could be causing this. I does not buck or hesitate it just has no power and sounds like a truck.

Try giving it a good tune up.

Plug wires, both coil packs, and a fuel filter.

Sounds like the engine is mis-firing.

I would first drive to an Auto parts store and have them scan your ecu for codes. A lot of them do it for free... Then depending on what codes come up you can trouble shoot more.

IMO I would not be surprised if it was one of your up-stream O2 sensors. or may be a dirty MAF

Here ia what I have done so far,
Plugs
Cleaned MAF
Swapped up stream o2's with the down streams.

Car seems to be running better but not at 100%. Im gonna do plug wires and I have a nasty exhaust leak that im sure is not helping. The car definitly feels stronger after the work done.

You did all that but do you have any codes?

It's 99.1% never a dirty MAF.
02's wouldn't make the car mis.

Check your coil packs with a DMM. (Primary and Secondary) Also check for a clogged injector(s). Eeasy way is to check/clear a ditry injector is; while the car is running use a 3/8 extension to touch the injector tapping on it (Lightly) with a screwdriver handle. See if that helps. If your car has low miles I would doubt this would be the problem.

CHECK YOUR CODES.

Problem solved!!!!

I cant believe it after everything ive done. I was under the hood just inspecting some stuff and I was trying to see where the red vacuum line that comes out of the plenum goes, so I follow it to the backof the motor on the passengers side and I see this connector looking piece laying on my VC. Turns out it was the connecter for the very last injector on the passengers side Plug it in and the car runs AWSOME!!!! I dont know how it fell off and how I missed it when I changed the plugs but she is back at 100% and I love it!

I hate it when that happens.
