Ford Focus Engine problem

Very rough Idle. Extremely low power on take off. Then between 40 MPH and 70 MPH it runs like a scalded dog, just as long as you push the accelerator only half way down. If you floor the accelerator, the engine bogs down. This bogging happens in any gear at any speed. New Spark plugs were no help.

Have you tried having your fuel injectors cleaned on it. the engine might not be getting enough gas at take off. it might also be that your gas tank fuel pump or the other fuel pump going bad

Clean Throttle Body (both sides, not just what you can see) and MAF (mass air flow sensor) [spray and shake to dry].

Low coolant and oil smells like gas. No white/blue

let your car idle go back to the tail pipe if it seems to be steaming alot , and or smells like antifreeze then you have a head gasket problem or a gasket leak alowing in directly into your engine

Engine races hot or cold

It sounds very much like the idle air valve is faulty as I have just had same sort of problem I fitted a new idle air valve and it has cured mine. Unfortunately these idle air valves are not cheap. They are about £70 from ford but you can get them on ebay for about £30 from partsdome
