I bought a 1997 subaru legacy outback 2.5
the car came from Minnesota wich means rust all over I'm in Florida. I replace half of the exhaust system, spark plugs and cables,and a fuel injector on cylinder 3. The only thing missing is a gasket on manifold. A mechanic run the computer and diagnosed the 3 cylinder was not working.
My question is....would that exhaust leak can be related to a misfire?
