Question about Ford Focus

1 Answer

I have a Focus 1.8 LX TDCI 06 plate. When i reach about 80mph it seems to lose power. It feels like the Turbo is being shut off. It still drives but theres just no power there. As soon as i turn the engine off and back on again it drives fine again. I think it may be the air sensor but i dont no where it is. Any advice you can give me would be much appreciated. Thanks

SOURCE: Car loses power when it gets to about 80Mph

the boost controller works by vaccum pressure on some turbo engines and if it loses vaccum to the controller it dumps all turbo pressure out exhaust instead of intake. I would check that if it were me. It could be the mass air flow though it is located in the breather tubing somewhere between filter and the intake manifold.

Power loss and black smoke?


I had a similar issue to this after I got in a VERY small fender bender (literally) in an 87 Turbo Supra. In my case, my pasenger fender got pushed in JUST enough to crack a charge pipe and cause a boost leak.

Basically, what was happening was the turbo would spool and build boost, the mass fair flow sensor would read all this air coming in and tell the ECU to dial up the the appropriate amount of fuel. When the air reached the cracks in the charge pipe, it would escape out of them. Thus there was a much lower air-to-fuel ratio, causing less fuel to combust, which lead to power loss and black smoke out of the exhaust.

My guess is either an oxygen sensor, or more likely a boost leak.

Good luck mate.
