mazda protege5 only firing 2 cylinders help!!

[Sheadensp5]

Hey guys , so my car would sputter and idle rough for a while now but now it's running on only the cylinders with the ignition coils above them. I have changed spark plugs egr valve cleaned new coils, cleaned maf . I don't know what to xcheck next maybe the timing is off? Let me know what you think thanks!

as rare as it is, the ECU might be messed up

^^^And if thats the case I have an extra...just saying...

Haha o yah forgot to mention I changed ecu

So if you have not changed the wires - GO DO THAT!

Stock are fine.

if it is only firing on the cylinders with the coil packs, then that means the #1 cylinder isn't firing. Perhaps a cam position or crank position sensor? (but yeah, I'd also start with the wires)

[Sheadensp5]
