Question : I HAVE been using a Waja manual since 2001.
When I let go my right foot on the accelerator in third, fourth or fifth gear, the car takes two to three seconds to respond, i.e. slowing down.
However, if the car is stationary, the rpm will respond instantly to any movement of the accelerator. What is the problem?
The obvious thing to look at is whether the throttle cable or any part of the linkage is sticking.
I am assuming that when you lift your foot from the throttle, you are at the same time declutching to shift gear.
If you are not declutching, then the engine is still connected to the transmission and the momentum will prevent the engine from slowing down.
On the other hand, when the engine is in idle, obviously the engine will slow down immediately when the throttle is lifted because there is no load on the engine.
