The person that told u that it was the tps and idle air they we're completely right!! The tps sensor is what makes it do that. If you pull the air intake of there's 2 holes on the throttle body. Plug one of the off with your finger while the engine is idling high and it should come down mine was the top hole. If it does go down just get a new tps sensor. and the back sensor on the intake to be safe. or the ghetto way is to plug the hole off, not my sugestion.

Engine misses when idling at 800 RPM when warmed up


The idler air control is not working like it should. try tapping on it with a screw driver lightly this should kinda fix the problem while u are tapping. This will need to be replaced if it starts agian after u stop tapping.

Idles up and down after warm, but goes away in reverse and drive. 1993 honda accord


I had the same problem with my honda. On the throttle body there is a screw that controls idle speed. If your idle speed is around 800-1000 rpm in neutral, tighten the screw a quarter turn each try until the idle speed is around 1500 RPM. Did this stop the idle?

Engine idling varies depending on light or aircon is on/off


dude its normal for first start or cold start that the idle is ok but it must high than normal... its normal because the engine is warming up it self... when it gets warm, the idle speed will return normal idle... your engine is 1200cc, it has not much HP for a great load... and i know its a carburatored engine and its an old engine, your head lyt and a/c fan and aux fan and all the electrical system on your car, uses the HP of you engine and its a lot of load to the alternator driven by the engine to generate an electricity they need and thats why the engine rpm speed lowering down to dead and its shake. thats why when you use your lyts or all electrical, you engine is weakening... the best remede is adjusting you idle speed... its located behind the carburator.. its a small black knob.. just make a twist each eighter way and you'll find out if your idle rpm speed ts incresing or decresing.. just increase it and try opening your lyts and other electrical, if its still shaking then adjust it a little more

Vtec check


hi you will know if it works it don,t kick in till the engine reachs a certain rev range usually around 3000 rpm then it transferes to the hi lift cam and when it kicks in will feel like a turbos been fitted. if not you have a problem with it which would likley be a problem with its solenoid or oil pressure. yates210456
