idle problems
 

ok so yesterday i was driving and as i was slowing down i pushed my clutch in and the rpm's dropped to normal but then went up to about 1500 rpm's then slowly dropped. But today it did it and then when i stopped the car would rev itself, like go from normal to about 1500 then back down and then back up and then back down. Can anyone tell me what is wrong with my engine please, thank you.

I'm thinking it might be a MAP sensor gone to sh*t, but I'm not the expert. did you get a CEL?

Try cleaning out the idle control valve with some carb cleaner.

Could be lack of coolant, too

no, there is no check engine light and where is the idle control valve located?

Underintake manifold. Start with the collant level, it's easier.
