- 2003 Mazda Protege5
Hello everyone,
I have an 2003 mazda protege 5. It was burning oil so my mechanic figured it was the valve stem seals that were damaged. he went ahead and rebuilt the head. After he put everything back together now the car has a harsh start. I got CEL with code p0300, so I figured i'd start by replacing the coils and the spark plugs along w the spark plug wires, however car still dying.
After doing some reading online my next option was to replace the EGR valve, which I've heard will cause the engine to stall out and misfire w the p0300 code. So I went to autozone and droped $140 to replace it, put it in this evening car is still drying, however the CEL has turned off.
It almost sounds like its sucking too much air in as it is making a weezing noise from the intake. I checked for any leaks past the MAF sensor and everything looks good. I noticed after starting the car a few times smoke started coming out of the catalyc converter which concerned me a little So i let the car cool down and just drove it back into the garage. At this point I don't know what to do, and I do not want to spend more money. Car is still smoking when I start it up.
from doing research online it leads me to believe the piston rings might be screwed but before the head rebuilt the car was running fine, it was just the burning of oil in the morning when I first start it up. car has 168k miles on it and is my daily driver.
I took video of the cars behavior and will put the links in as soon as I get the videos uploaded to youtube. Any advise/help/pointers are appreciated.
