I have a 2000 Mazda Protoge ES with the following details:
1.8 L I4 w/SMFI
The car has been running fine. In the last week I found a CEL code for random misfire and misfire in #4 cyl. I removed the plugs thinking that the ignition system may need replacing. I found coolant in two cylinders which tells me that the head gasket is leaking.
I'm looking for advise on doing the job myself (e.G, parts, special tools, known problems, etc).
I am not a pro but have extensive experience under the " shade tree". Even built/rebuilt a few engines.
