abnormal loss of speed

[FATHY]

I hesitated to start this thread but I searched this forum and I couldn't find an
answer to my question.

I have 320 i 88 model m 20 engine .it starts fine , idles fine.it accelerates fine but on high ways at any speed and even on slopes once I took off my foot of the gas pedal, the rpm decreases quickly .say I'm driving at 140 k/h,once I take off my foot ,it goes to 100 km within 5 or 6 seconds EVEN ON SLOPES. WHAT COULD BE THE CAUSE?

Sticking brake calipers. Id check that first. Jack up the car at different points and see which wheel isnt rotating freely.

I think you are right.I will check them tomorrow.Regarding the injectors ,mine are relatively new .just 1 year old.good uck

Brakes would be red hot if they were dragging all the time, especially at high speed.

Auto or manual?
