More details. Throwing any codes. Its a stick I guess, so do you give it gas and it just dies? Does it happen when you start from second? Give us as much info as you know.

yes its a stick. No its not throwing any codes. Its just when i stop it starts to die and when i give it gas it kicks back in. I dunno this is the first time i have ever put gas from this gas station in the car. It seems to have some power lose to.

If your car is having trouble keeping idle 700 +/- 50rpms , then you need to take apart the air intake system and clean the throttle body and IAC valve.

1. remove air intake housing or aftermarket intake pipe.
2. remove throttle body. this is the thing with all the hose attached to it. most of the vacuum lines pull out, the ones held with clamps that connect to the IAC valve are coolant hoses. Make sure the car is cold and the radiator cap is removed before disconnecting these.



then pull the throttle lever open and disconnect the throttle and cruise cables by sliding the pin out through the hole. then remove the 4 bolts (red highlight) holding the throttle body on the intake manifold.



remove thr throttle body and clean all the carbon off using a throttle body/carb spray cleaner. metal polish makes it shiny.



remove the three screws holding the IACV to the throttle body and take it off. there are gaskets between the icav and tb but also between the tb and intake manifold. you can get new ones from honda (recommended) or reuse the old ones. spray carb cleaner all inside the valve openings and use q-tips if necessary to remove all carbon. this may take a while and require alot of spraying. it should look like this. If possible, let the piece dry overnight. Otherwise use a hair dryer to remove most of the liquid residue and reinstall in a few hours.





Put the IACV back onto the throttle body and reinstall on the car. be sure to tighten the bolts to 20 ft/lbs and reconnect all the coolant, vacuum, and sensor lines along with the throttle cables. reinstall the air intake.

IDLE LEARN

After installation of TB is complete, start the car and drive it until the engine is at full operating temperature. Idle may be rough or erratic at this point.

Park the car, turn off the engine, and pop the hood. Locate the fuse box and lift up the top cover. Using the supplied fuse puller, remove the FI ECU fuse for at least 10 seconds. This will reset the computer without erasing radio presets.



Replace the fuse and close the box. Make sure that all electronics and accessories are in the off position (fan, a/c, radio, lights, etc). Start the car and let it idle for 10 minutes with the hood closed. Do not press on the gas or turn on any accessories during this time.

After 10 minutes, turn off the car. The idle speed should now be set. Start the car and go drive like you normally would so the PCM can relearn the fuel maps. Idle should now be smooth.

that is the second time i seen that. lol ..

but i had the same problem and turned out that there was a piece of metal wedged in my EGR valve. take the EGR valve off anf check. it will be noticableif its wedged in there. if there is sumthin in there remove it with a pair of pliers but be careful not to damage the mating surface. then clean it out with carb cleaner and clean out the part it mounts too with carb cleaner. even if you take it off and find nuthin still clean it out with cleaner just to be safe.

egr malfunction is very rare, its the first time ive heard that happening in 5 yrs.

you can also check the vtec solenoid if you have EX, if its clogged it will affect how the car drives over 3k rpms and also affect how the car starts.
