hey i drive an 01 cavy Z 5speed gotta problem the last few days i have been noticing that when the weather is cooler in the morning or at night sometimes when i am pushing the gas down the rpms go up then just stop like it cant give it anymore it will just sit at about 3.5rpms for example and not go up even when i floor it then a couple sec later it catches up and starts climbing again, it only does this shortly after just starting the car in the morning and evening once it gets going for about 5min it doesnt do it anymore or if its hot outside nothing but it nevers loses powere conistently at a certain RPM whats going on???

Check the spark plugs. Try some fuel cleaner. Let us know if that doesn't help.

will do give me a day or so and i will let u know
