help!!!! engin power loss at speed
Please help me i drive a 2003 ST170. And at high speeds after long journeys or hot humid weather my car starts to kangaroo as if theirs no petrol (even with a full tank) usually around 3000 - 4000 rpm especially when i ask the engine to accelerate. i have changed spark plugs, manifold inlet thingy, coil pack, air filter & fuel filters. their are no engine management lights and its really frustrating as i work 1hr from home so this happens every journey, i have asked my local ford specialist but they suggested the manifold inlet thing at considerable cost but no luck.
