check your throttle cable? i guess make sure nothing is stuck the cable itself and the gas pedal i guess this is weird

LOL

There should be a valve like this on the bottom of the throttle body or either on the back of the intake manifold.

Take the two screws out and there should be a white piece with slit on each side like in the picture below. Take something like a gasket scraper and tighten that white piece back down. Should fix the problem.

Feel free to take it completely apart and clean it all out if you can. It will prevent other idling problems.

Try unplugging the tps and starting the car...ur car will throw a CEL but if its the problem then it should idle fine.

i did that it still did it but i found the problem my intake gasket cracked on the 4 cylinder because i sprayed carb cleaner where the intake bolts up to the head and it stopped as till i stopped spraying so i got to find a intake gasket

i just ordered a gasket from honda because the dude at a the parts store told me to make it out of paper gasket maker but then i checked at honda and they ordered me one it should be at honda by Monday or Tuesday because no one can get the gasket for it because they said it was to old of a car


hope you get it fixed

Hondata makes a great IM gasket for that motor....helps keep the plenum a little cooler as well.

Sponsors on Honda-tech sell them for like 55 dollars shipped. They are more expensive but are pretty much indestructable
