- 03 mazda protege 5 automatic
Misfire and running rich.
Car was idling rough and stalled. Pulled a coil pack and it was dead.
Things Ive replaced/done:
-new NGK V Power spark plugs
-new NGK spark plug wires
-New Napa Echlin (oem replacement) coil packs
Same codes still being thrown. Car runs a little nicer.
About 15k-20k miles ago I had help installing a new EGR valve (the upgraded version I read about on here...turns out it was the cold weather/Canada version. ooh well, worked great). I installed a new radiator +cap, ect sensor, thermostat.
Head gasket repair, water pump, and timing belt around the same time (from shop).
Recently put in a catch can and new PCV. I noticed that the PCV had oil on it.
My goal today is to clean the MAF (did it 15k ago) and clean the EGR. This guy's channel, https://www.youtube.com/watch?v=Q9YPBt-EG14 seems to be helpful for that. Hopefully, I'll test the 02 sensor, but might just replace both since I dont know if thats ever been done (Im the 3rd owner).
Fwiw, my exhaust does not smell like rotten eggs and I have always passed smog, and my mpg has always been around 25-30. About a month ago, my gf put way too much oil in (she does her own oil changes, just a stupid mistake) and ended up stalling the car. Didnt drive it anywhere. Drained some and its been fine...and then she put a little too much in again the other night...I will now be the only one to do my oil.
My checklist:
A code P0300 may mean that one or more of the following has happened:
X- Faulty spark plugs or wires Faulty coil (pack)
O-Faulty oxygen sensor(s)
O-Faulty fuel injector(s)
O-Burned exhaust valve
O-Faulty catalytic converter(s)
O-Stuck/blocked/leaking EGR valve / passages
O-Faulty camshaft position sensor
O-Defective computer
