Hi guys
My prelude has rough idle that's too high and sometimes jumps up and down.
I read all the threads about that kind of situation and now I have a more serious problem.
Normaly there is suddle roughness in accelleration but now it barely acclerates at all and its hard to get going faster than 40mph.
I was told that TPS may be to blame for my rough idle, i'm not sure that it's true.
I also read here that vacuum could be the cause of my idle problems.
I'd apretiate if you guys could give me some advice on weather it's vacuum or TPS or anything else that's causing acceleration difficulty.
