My car is misfiring and also has a very low rpm when I am at a stop. Here are a few symptoms.

- idle drops to around 500 when I am stopped and turn the wheel
- idle is very rough
- abs light comes on when I put it in drive


Changed out distro, plugs and have cleaned my iacv.

Car is a 1997 Honda accord with a jdm h22 running a p13 chip.

 

i see this engine is in a accord check if u mixed up map sensor and tps the plugs are the same and fairly close to each other ... will cause miss firing

 

Picture ?

 

Sorry I don't have a pic but the tps. Is located on the back of the throttle body if u don't know what that is its the part were you intake hooks up to with a hose clamp. It's a three wire connector and as for the map its located right on the top off the throttle body if u are using a h22 throttle body you should post a pic of your engine bay maybe I can help u better

 

What is your email ? I have the f22 throttle body on for cruise control. Will check connectors tomorrow.

 

The problem with using a different throttle body is that the idle setting and the port for the h22a is different than the f22. You should readjust the base idle. You can do this by pulling the iacv connector while the the engine is running. Then set the base idle to 550 or 600. Keep in mind that the first white mark after the original white mark for 0 rpms is actually 500 not 200. After you got it to 600 turn the car off, put the iacv connector back on and pull the radio/backup fuse for about 15 minutes. It's important to wait about 15 minutes. Put it back in, let the car cool down completely and restart it from a cold start without touching the throttle at all. Wait all the way until the fans cycle on twice and then turn the lights on and wait another five minutes or so and you should be good to go.

 

Alright, I will try that today. You adjust the idle by the screw on the upper left hand side of the throttle body right ?

 

Yes. You shouldn't need to move it much if at all.

 

Alright, set idle at 600, pulled fuse and I am waiting with car completely off, no key in.

 

Still have same issue.

 

Try and pull some codes see if its random misfire or just a certain cylinder also triple check your firing order if u have the wires mixed up just even one it will run like chit search the should be something on the correct firing order

 

clean your egr ports, also check for vacuum leaks

 

How do you check for vacuum leaks ?

 

Did you check to see if you swapped your TPS sensor and MAP sensor connectors ?

Are you throwing any codes ?

 

The two sensors are in the correct place. No cel on

 

Does it only do it when you turn the steering wheel ? Keep in mind that the power steering system is mechanical as it relates to the idle. When you turn the steering wheel it creates a load before the iacv can react to it whereas with the ac system it will delay the turning on of the ac until the idle is bumped up to compensate for it. If the idle goes low while at the same time you're either creating another load or pushing the brakes then the idle is going to dip.

I hate to ask this again but did you read what I said about where the 500 rpm mark is ?

 

Well if you are in the north jersey area feel free to bring it to my shop.
