wow what a improvement. i finished installing the intake manifold gasket this morning, #4 gasket was blown out. the second the car started i could tell that was the problem. no more reving idle, sputering, rough idle. i hope im not jinksing myself, i havent taken it out for a test drive yet but so far so good. next project is replacing the passenger side motor mount. is this a diy project? it doesnt seem like it would be that hard. also need to replace the oil pan gasket. is that going to be hard to do?
