My dad in law has a 200k 03 ba 6cyl falcon..its has for a month had an inttermitant miss..a bad one at that..to the point where it feels like it is running on 4cyls...it does it from cold start for a few mins while driving and then clears..
Things done to try and remady this in the last week..
New plugs
New coils
New inlet manifold gasket
New injector O rings
New fuel filter
New oil and filter
Codes read and cleared..only one to appear was coil..
Auto serviced

This is getting frustrating as it is a much loved nice car..
Any ideas tils etc would be appreciated..cheers

Hey mate my BA was doing the same thing. My mechanic used (I believe its Wurth branded) intake cleaner. I believe you spray it into the intake while the engine is running, it blows some dirty black s**t out of the exhaust so don’t do it on your drive way… But it ran like a new car after. Maybe worth a try, think it cost like 20 bucks… So couldn’t hurt.
Jump on youtube and i think you’ll find a lot of videos of it. I’m sure there would be a few people on here that would know what I’m talking about and probably can tell you more about it or if it’s good or bad… It seemed to work for me.
Cheers Paul.

Cheers that will be done tommorow but poroblem has seemed to dissapear..strange.

Mine was very intermittent as well. Hope you get it sorted.
