can a misfire be related to exhaust leak?

[Morris5711]

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?

If you replaced injector 3 and cylinder 3 still isn't firing correctly, check the wiring going to that injector for power. If the injector IS working, there might be an issue with the coil pack where it's not sending a strong enough current to the plug.

 

Also, get that gasket installed and the issue might clear up. Especially if it's an intake manifold gasket as leaks there will cause all sorts of issues.

Thank you so much Bushwick. I did check the coils and there's current on that wire. I really hope is the gasket. It's the only thing missing to fix on that exhaust. And it's the y member under that cylinder.
