Hello, my car started making lots of misfires when i went at a track day for the 1st time when i was keeping the revs high all the time. So i changed my coils for oem ones, changed spark plugs, tryed again to see if it would do the same thing and it did. Changed the spark plugs wires and saw my cat was glowing red, went to dealer to change it under warranty. Got my car back today, tried it again, and still, same problem...

I got :
New coils
new spark plugs
new spark plug wires
new cat
Injectors cleaned with redline fuel system cleaner
maf cleaned
seafoamed


my mods :
mazdaspeed cai
rx7store catback
running premix

My car is a 07, 80k km on the meter, never abused before 60 k km.

i'm gonna clean my ESS today,

checked out this link : http://foxed.ca/rx7manual/2003mazdar...200300W02.html but didnt not told me much. my car starts fine(hot and cold) never flooded, running 10w30 mineral racing oil, my coolant level does not move so it's not taking any.

what's left? fuel pump? compression test?

help me! i want to track it :P

 

What are the codes?

 

The last time i checked it was p0302, i guess its the same today. i dont have a AP or CEL reader.

 

Did you reset the NVRAM (eshaft profile). The sensor could need cleaning.
Its an induction sensor so any metal bits can cause irregular readings.

 

i did the 20 brake pedal push thing, nothing changed, tried to remove my ESS and it's stuck there. mine is not made like the other(older i guess), instead of the U bracket with the bolt at the bottom of the U, mine is a circle so the ESS is inside that hole, bolt at the same place. I sprayed it with some WD40 and will try again later, i'll also try to reset the KAM thing when i will clean the ESS

 

test if each coil is receiving proper current...also, there is a chance that one of those new coils simply came DOA (this would be the least surprising)...
