I don't know what happened!!! driving at low rpms, good oil level, everything normal. My 2001 protege 1.6 litter made a whistling sound and lost power. After pulling out on the road I openned the hood and noticed air coming out of the number two cylinder... I continued two remove the two 10mm bolts holding the sparkplug cover and what a surprise! the spark plug was shot out into the cover with melted plastic all over. I am an aricraft mechanic and I'm religious on the maintenace. I have 65000 on my car and done every sceduled maintenance (including the the 60000). Don't know what happened... did the cylinder head got o hold of the spark plug? Am I going to have to change the engine? Itsa a Mazda engine, only 65000, whats going on? please help... (boom07)
