i have a 95 integra gsr.....and the idling is up and down from 1 to 3 rpm's even when its warmed up...there is this hole on top of my throttle body that looks like it originally had a vaccum on it and its now plugged up...could my idling problems be offset timing or something else?the service light is off....and it doesn't surge when im driving

Hi Jihm20 and thanks for your question.First let me say I hope you stated your question wrong. If your car idles 1-3 rpm up and down , not to worry. But if you are saying1000-3000 then there is a small problem.The port you are referring to does not have a vacuum to it. Unless it was plugged up with something like silicon or some other substance.For a engine to surge as you are saying is not normal.What happens when you drive does it serge when driving?there is a device called a throttle position sensor.If it ig oing nuts it will tell your cars computer it cant find the right place to set and the idle goes up and down.You also did'nt say if the service engine light was on or not.So what do you do? come back here with if the light is on and if it goes up and down when you drive and let us knowThank you for your question

If there are no codes try cleaning the throttle body and make sure the accelerator cable has a bit of free play. A sticking EGR valve will also cause a bad idle.

Its either a gasket problem, manifold, or the censor in the back, this happen to me, best thing is to take it to a Pro, have them fix it so you wont run into major problems.

ok sounds like a vaccume problem follow this steps; 1. put your finger where the hole is while the car running if it sucks it in theres your problem. either plug it or find the loose hose. 2. theres a sensor called AICV(air idle control valve) its located in back of your intake manifold. remove it, theres 2 holes one is open another has mesh, clean it with brake clenear try not to use carb cleaner it might eat up the little gaskets.ohh this sensor also has 2 hoses with anti-freeze. if you want add a little gasket maker to seal it good. 3.it might be a busted intake manifold gasket so get some started fluid and while your engine is cold and running spray a little where the intake manifold and head bolt on together. if you notice a diference like revs go higher than normal it means its the intake manifold gasket. do this only when engine is cool down since starting fluis is highly flamable. 4. after finding your problem fix it remove any code from your computer by removing the fuse for the clock for about 1-2 minutes or just unplug the battery. if you unplug the battery your original acura stereo might get security lock....
