So my engine obviously has something wrong with it. It does the whole up and down idle thing while cold and if you ever give it full throttle, it will hold any rpm your at and just sit there and sputter and not stop. The only way that i can accelerate is to just barely give it any throttle and crawl up to the speed limit. Please help me!!! I installed a new primary o2 sensor and a new tps sensor. I will look at the IACV and fuel filter but haven't yet.

 

Your idle is almost sure air pocket in fast idle control vavle. The rest looks like you are running too reach. How is your mileage?

 

definitely down from normal. I would say at least 3-5mpg less. How do i fix the idle problem first?

 

Drain and refill your coolant, being **** about following your manual.
One more agrument for running too reach, but I never really had honda doing this to me, so I would leave it to others to answer.

 

What kinda engine mods did you do?

 

what year and how many miles ???

 

That happened to one of my freinds hatch when he was at a stop it would idle up to about 3 thousand and drop and go back up, and he had a new o2 sensor put in and it stoped.

 

You can try adjusting your trottle body idle screw it mite be loose, that can sometimes happen.

 

do you have the coolant lines connected to the throttle body? they will cause an idle surge if not hooked up. any CEL's? i know that same thing would happen to my car every once in a while and i would have to slowly accelerate. it threw the tps code, and the map sensor and speed sensor all at once. but that was an intermittent problem

 

Sorry for the delay. The motor is stock the only thing that has been is the bottom portion of the intake has been removed. Everything to the TB is correctly hooked up and I took it off and cleaned while changing the tps sensor. While driving it just now, the only way to get the car to go was to just barely touch the gas pedal and shift really low. Anything over 4000rpm or so would just sit there and studder.
