New Plugs,WIRES and Coils Still misFires!! HELP!!
HELLO TECHIES!! Im from Calgary AB CANADA. so i have an 04 rx8 6MT COLOR: winning blue with 105700km on it. Did a Compression test and my rotor#2 is running a lil low on specs..bought the car privately and so i've done tons of things new calipers breaks and rotors about to do an oil change when i was driving home and it started misfiring.. got P0300 code..
i've replaced coils wires and plugs 2 days after all genuine mazda parts.. except the wires are NGK! runs sluggish and sounds like clogged and kept misfiting what should i do now?.
ohh, i deflooded it once right when i replaced all the plugs wires and coils and still wont start so i de flooded it.. worst scenario hopefully my CAT isn't clogged..
warranty is done on this car since april 2012 which is last year.. just recently cleaned MAF sensor coz theres a lil oil liner on the pipe. any advises guys? im all ears!!
I know an rx7 specialist in town but i wanna learn on rotary and DONT wanna spend more money.. Sucks when you see nice cars out on the road and you cant drive you own..

Stop driving it, if it isn't your cat it will be if you keep driving it. Drop your cat and look at it so you can see its condition. What were the results of your compression test and at what rpm?

Recheck your work first.
Countless people before you think they have everything perfectly done, but later find out that they either routed the spark plug wires incorrectly, installed the leading plugs into the trailing plug spots, or didn't properly snap the wires onto the plugs and/or the coils.
First double check your work, then start performing more tests.

i dont have money to spend for new CAT if its bad.. what if i gutted it instead? or a cat delete downpipe? i know for a fact my sensor is going to sense a different mixture.. is there any chips or hack chips that can fix that issue..
xexok: i have the compression test result at the shop.. il post the ratios soon as i get it..

have'nt done the eshaft memory reset.. but i do have an obd sensor.. recently codes cleared were P0300
U0073 - PCM
U1900 - ABS.. about this two codes got me a lil confuse coz sometimes it pops out and sometimes it doesn't. I've notice the PCM and ABS pops up 5 mins before my car misfired.. but i doubt its part of it.. im guessing its my CAT and since i brought it in kramer mazda dealership here in calgary for a compression test and talked about if i still have the warranty.. and of course they said they dont have enough evidence that my cat is going bad since its running ok (they never even brought down my cat to even specify they really checked it) and later after they were done said my warranty is out dated lol.. i did 245km on a full tank.. that just said my cat is clogged or my MAF sensor is dirty..

Step on and release the brake pedal 20 times as quickly as you possibly can. If you do it right, after the 20'th stomp, the oil pressure gauge will sweep right then left. Turn ignition off, then back on, and restart the car.
I would recommend letting it idle for about 5 minutes. Then drive normally.
And you really should have posted this in the Troubleshooting section of the Series I forum.

Got to agree with Bladecutter, recheck your work and electrical connections to Coils and also Plug Leads to Spark Plugs, not mixed around.?
I would have renewed Plug Leads (Wires) @ that mileage.
Also reset PCM as BC says above.
Being an 04 does it have original engine?
