[repthemazdas]

want to see what yall think....ok when it gets warmed up it sounds like it has 2 cylinders lol....and then when i take off it sounds like it has 2 cylinders!!!lol its poping and backfireing everthing... and just not good.......

MY THEORY

coil packs r gone
spark plug wires r gone
maf sensor
and 02 sensors

Get the codes read at your local auto zone or big box parts retailer.

I'd guess coil packs .... but that should make the car throw a check engine code.

First thing pull your plugs and see if there is an obvious difference. Don't think coils will cause a flashing cel unless there is a broken or frayed wire somewhere. Check cam position sensor (had a frayed wire once causing a flashing cel) injector wiring, coil wiring and even the iat (had a broken wire also caused flashing cel). Does the cel pop up right away on a cold engine?

Has anything else been messed with lately? Check spark plugs first then wiring as I mentioned

Those electrodes generally don't just break off. Have you checked to see if your car is one subject to those screws coming loose and falling into the engine. I forget the name of them ...

You're referring to ViCS recall. Here's the link to my thread with info and symptoms regarding ViCS problem/recall. http://www.mazdas247.com/forum/show...re-occuring-problems-amp-and-vehicle-behavior

Correct DiS ! I couldn't think of the name.

Also, a bad coil will DEFINITELY throw a CEL code. I had a CEL in my daughter's 02 LX, and if I recall correctly, it threw a PO300 code (I think ... not positive on the exact number) which was 'multiple random misfire' .... I researched it, replaced both coil packs for about $70 total, and the issue was resolved.
