like the title says my car when its warmed up it idles very low and when i slip the clutch out a little it starts to almost die and when i rev it a little and when the rpms drop it drops to abut 100-200rpms i haven't done anything to it, so does anyone on H-T know what can be the problem?

 

Check your IACV and your PCV valve. Also see if your throttle body is all gunked up.

 

how do i check IACV and PCV valve to see if its functioning right?

 

You can pull your PCV valve off to see if it is all gunked up.

I honestly don't remember how to check your IACV.

 

alright im going to check it right now thank you

 

step 1 buy carb cleaner step 2 remove and spray carb cleaner in both ends of pcv valve. step 3 look on the back of your intake manifold youll find something that has 2 black hoses going to it. those hoses contain coolant. undo those, then undo the electrical connector then the 2 bolt that hold it to the manifold. spray carb cleaner in it then let it dry. then get some wire and hook it up to the battery and see if it goes in and out the little white thing inside. there are 2 holes in the iacv that are round one has a screen one does not, just saying that so that you will know if you do infact have the iacv in your hand. also before doing any of this disconnect the negative terminal on the battery. good luck. and also check your fuel filter and air filter if this doesnt fix it.

 

If you pull your PCV valve out and its good, you should hear a little ball rattle inside. If you dont hear it, then its bad.

IACV is really easy to clean and should solve your problem.
