I have a chevy blazer with a fully rebuilt v6 in it with only 8000 miles on itand ran fine for a while with no problems at all and it has had random cylender missfire ever since the weather got colder. All my ignition parts are ok they are not causing the problem at all. My mechanic said that I have a vaccum leak so he retorqued my intake maifold and it helped a little bit but he still says that I have a vaccum leaks somewhere. Ho do I know for sure that I can automaticly rule out the intake manifold gaskets because like I said they are not that old. This engine missfire is really bad when its cold but gets a tad better when its warm sometimes the engine dosnt do it at all. And also to nothing is leaking or reqireing any fliuds at all. Thank you!
have the same problem?
