I noticed my car(civic vti 99) would on a few occasions have poor acceleration but rev really high and when this was happening I thought my clutch was on the way out. However after a few intermittent occasions this symptom disappeared.
Though the worn clutch type symptoms has disappeared, the car doesn't feel as peppy or vibrant as before and the sound isn't crisp like it used to be. I havea feeling whatever caused the car to loose acceleration and rev high on those intermittent occasions may still be present but in a mild way hence I cannot notice the symptoms.
Garage recently compression tested car and checked ignition both of which came back fine
The clutch does seem to be ok. Can you think of any issues which might cause a car to have the above symptoms in an intermittent way?
