On an 11 year old car I would suspect a possible vacuum leak. Check all the vacuum hoses under the hood. Can also be a defective EGR valve. Are you sure the Check Engine light is working? This should trigger the light. Turn on the ignition without starting the engine. Look see if the CE light is on.
the fuel filter has been changed.
your neon sputters from old spark plugs and plug wires. i changed both and problem went away.
check spark plugs, plug leads, distributer cap and rotor button
well they changed it and its not realy good
check the vacuum hose which goes to the MAP sensor, $4 part.
Did you get the alternator tested?
No. they must be increasing speed to accelerate.
could very well be the injector. could also be the distributer or the plug lead
Because you accelerated. The engine speed changed, so the oil pressure changed. As long as it never drops below about 10 psi, it's fine.
The cat is my guess, i have a 96' Firebird, and my car had a HUGE loss of power, it was a bad cat, what happens is the cat gets clogged from unburned gases, particle buildup, pretty much anything can clog it, it can be caused from misfires, no fire from one cylinder, lots of things. Mine was caused from misfires. A bad cat kinda smells like rotten eggs. if you have any more questions, email me at systemat1c@live.com. (Cat stands for Catalytic Converter)
The reason why it is vibrating is cause of the Engine Mounts. You have to get the Engine Mounting changed ! cheers.
No other code? Just "random multiple misfires"? That's odd. There should be some additional code along with the one you describe.
