My ef xr6 is running real rough and after u give it a bit and drop a mate off for example u can smell it's running rich. It's been doing this forever. I have replAced leads, plugs,oxy sensor and now I'm thinking it's injectors I ran a bottle of cleaner thru it ages ago bit it could of been beyond that. Any thing else I can do? How much is it 4 injector cleaning?

vac leaks or MAP sensor. I'll bet that'll be the issues

Cheers Val line wise were would u start? How many lines are there. Also were is the map sensor on the i6?

Cheers. Is there anyway 2 check for bac leaks

lots of threads on these things already, but just for you


There are about 6-8 vac lines on your car. they run every thing from brakes, AC, engine diag, idle, fuel ratios, fuel reg etc. They measure or use part of the vacuum created in the manifold while the engine is running.

the MAP sensor and fuel reg are against the firewall passenger side. simple inspection and suck test will tell you if their shot.
