Yet another freakin problem...

Well.... now for some reason the car is running like absolute crap. I started it up tonight and thought that the idle was a little low but started driving it. Anything after about 1/4 throttle, the car backfires, stutters, hesitates and basically loses all power. Once you let off and it is under 1/4 throttle, it revs fine. I found this is more at lower RPM's. Once the engine is reving over about 3-3500 RPM you get get into about 1/2 throttle before it starts acting up. Once home, I got under the hood and you can really hear a hollow bogging sound and the smell of Raw fuel is pretty bad. I am taking it from that that it is spark. WOuld this be the coil? DME? Any ideas?
Thanks

Check the action and movement of the AFM, sounds like the spring went out and the barn door is not openeing correctly.

Have you rinsed the engine compartment lately? Just curious.

One thing I hadn't thought of, thanks Scott, I will check that out.

Matt, nope haven't done any cleaning under there lately.

Talked to a mechanic friend of mine and he said that this may be caused from the timing belt skipping a tooth. I replaced the belt about a month ago and it is getting close to retensioning time.
What are your thoughts on this?
Thanks
