well this is my car´s problem. at idle everthing is ok after the engine is warmed and when the rpm , the accelaration pedal , is stady i am having sth like loss of power , rpms are running up and down . if i press the pedal everything it is ok but if i have stady the pedal - rpms again i have rpms up and down sth like loss of power.

well i have changed sparks and plugs , not yet coil pack , fuel filter and pump , also cleaned the injection , throtl possition senson air filter

pléase if anybody can help ....
 
you should check your exhaust for loss of back pressure. that would make it feel like its losing power. your Catalyst converter may be out. ive had the insides of mine completely fall apart (its the honey comb looking think inside). check into that.
