searched but couldnt find my answer. The thing is, while driving in gear and going to neutral my idle sometimes goes down to 200 rpm, but as i let it idle it goes back to 500-750. Is this normal? because when i first got my car back from a valve adjustment and timing, the car idled at 1000 and stayed to 1k-900 rpm. thanks

 

i would get your timing checked again.

 

started my car in the afternoon and idle was at 1000k on the dot. The weird thing is that my low idle usually happens when its cold. Also im throwing code 1 but i only have one o2 sensor before the cat (no cat).

 

i think i found the problem. When i changed my intake manifold i remember the iacv was dirty and i tried to clean it a little but pushed the screen in more. Can i take the iacv off to clean the screen without taking off the two coolant hoses, becuase i remember i almost fainted trying to take them off with pliers.

 

pls dont bother with my 1k typo

 

its possible but you might get tired of working in such restricted space. taking it off will give you more ease to clean it. use any lubricant and pry that hose off it should loosen up.
