I have a 98 civic with a b16 swap and a jackson supercharger it has a hondata ecu. i bought the car with a bad idle and i cleaned the idle air control valve. the car ran better for a few days but then the idle went back to being the way it was. now 2 months after buying the car its been acting up. if im driving down the street and just barely touch the accelerator it does nothing until i give it more gas and then it jerks itself, but i can see the vaccum gauge go down so my throttle body is opening like it should. i think its probably my throttle position sensor. and 2wice in the last 2 weeks its done this thing where it just dosent have any power and wont go over 4500rpm if i let it idle it dies on me i shut it off and clean the throttle body and it starts up just fine and goes back to normal. any sugestions???

 

Cel? Is it tuned or on a basemap? Do you have a wideband?

 

check out my threads. i had similar problems

 

That sounds like a TPS problem. Either wiring or the sensor itself.

Hook the hondata up to your computer and data log the TPS values to confirm.

 

take it to your closest tuner

 

its tuned and running hondata s300

 

do i need special software to hook it up to my laptop?

 

i dont know if its a wideband or not. the air/ fuel ratio gauge seem too run lean most of the time tho specially at low rpm and idle

 

No just install it from the disc if you have it if not download it off hondata.
What brand is it? You don't know is its a wideband or narrowband?

 

Who tuned it..?

 

it could be a lot of things need more info.

 

i dont know what brand it is or if its wideband or narrowband. it was tuned at Revhard in Rock Island, IL just before i bought it. and what other info do you need? i really want to get this thing running good. note (the header has a leak at the colector but i didnt order one until i fix this first.

 

Replaced the tps this morning and seems to be running great again. Whats a good header for under 150 dollars? I saw this one online. http://item.mobileweb.ebay.com/viewi...id=06553730111
