I have a 2002 Protege5 with about 64K on it, I am the original owner and have been doing pretty much all maintenance myself.
It all started a couple of months ago. My CEL came on for the first time.
I had the codes checked at Auto Zone and it said P0304 Cylinder four misfire.
1- So I looked at the spark plugs (NGKs) ($10)and indeed number 4 looked really bad. So I changed the spark plugs and reset the ECU and the light went away for a few days and came back again.
2- I thought, OK time to change the original plug wires. CEL went away for a day or two and came back. ($65) (pissed)
3- Time to change the Coil Packs, ($90) I thought. No help, and the light came back again.
4- Removed, cleaned and replaced the EGR valve. No help
5- Complete Fuel injector Cleaning.($59) No help
6-Changed the #4 Fuel injector itself.($110) Samething.
7- Removed fuel pump and cleaned the "fuel filter". No help.
When the light comes on: I feel the car is very sluggish. It struggles to maintain speed and feel like I am dragging a tractor behind me.
When I reset the light, the car feels completely normal and drives just fine. Also when the light is on the engine sputters and shakes like it wants to stall.
I am running out of options. I'd hate to take to a dealer and have them rape me.
PLEASE HELP!!! Anyone else had this problem? and what did you do to fix it ? Any idea is welcome.
Thanks.
