ok I have a 95 hatch with b16a2 on stock p28.

im throwing 3 codes 7,21,41

I was running a non v harness so vtec was not hooked up.

and i was open header cux I had no exhaust.

tonight i am hooking up my vtec engine bay harness. wires were previously ran for vtec into the shock towers.

and this morning I had an exhaust made and 02 bung added.

now the tps is not set but seems to run ok where it is set.

there are no vacuum leaks and everything else is hooked up.

my iat sensor is plugged in but just hanging because i still have an obd2 manifold on my wires wont reach to my intake. I thought that might have been the problem so I unplugged it and its still the same.

what else would make it idle at 2k? I adjusted the dizzy but it only dropped 500 rpm and was bogging like crazy so I put it back. anyone have any ideas?

I am not really sure how to answer that question but I have basically the same setup 93ex w/ p28 and a b16, you do know that your stock p28 needs to be chipped to run the b16 and you should also know that if you are running the stock b16 injectors, which operate at 2-3 ohms you need a resistor when running the p28 which was made for 10-12 ohm injectors other wise your ecu will likely be fried in a short amount of time, although it looks like you already did because you don't have a code 16, but once you hook up the vtec solenoid that should take care of 21

ive had this motor set up in 3 crx's and my last 95 coupe. im on obd1 dizzy and injectors. it has always ran good and never idled like this.

update. I unplugged my ivac last night and it dropped rpm to aout 1200. I think all is fine and dandy until I take off to drive it. it wont rev over 2500. so I plug it back in and my idle shoots back up to 2k. wtf is wrong with this thing?

bakomack

anyone have any advise?

dosplunder

Check for vacuum leaks again. I know you said you did, but that is usually why it does this.

bakomack

I re checked my self last night. when I unplug the ivac rpm drops to 1200. I can adjust it from there but when I plug it back in it shoots right back up. is it clogged or something? I know im not the only person to ever have this happen to them. and idle does not fluctuate, it holds constant at all times whether its low rpm's or at 2k. no I dont think its a vacuum leak

its gotta be because of your ecu. you need to chip it or get the P2T. your iacv is staying open, so cleaning it may help but its ecu controlled and its making it stay open so that way the engine will run

bakomack

when I had my crx I ran on this exact same set up with this exact same ecu.

I have a p06 ecu I can try and see if my idle drops.

I do have a p28 with s300 but I dont have the cable to hook it up to my laptop to tune it. I wanna just run off a p30 base map maby drop v to 5500.

im running the same set up a b16a2 with a stock p28 and it idles around 1000 but drops to like 500 because its the wrong ecu ... i know that there is a screw on the throttle body that looks like it connects to the intake manifold ... i forget what its called idle control valve or something like that... well anyways if you turn it one way you should increase the rpm at which it idles the other way should drop it

gsr1379

i had a b16 do that to me. when i put the TPS on i missed the V thing the notch on the sensor goes in and was holding the throttle to far open. you could try to reseat it.

bakomack

we adjusted it already thinking it was off. it dropped 500 rpm but was WAY sluggish so I put it back



I had a broken tps so I put a new one on, but never set it as I dont have a multi meter. im also throwing a code for the tps too. think that could be the problem?

[QUOTE=bakomack;37268541]we adjusted it already thinking it was off. it dropped 500 rpm but was WAY sluggish so I put it back


you know that its ganna feel like its ganna turn off cuz the ecu doesnt give enough fuel to the engine cuz its for a single cam not double cam

redline7070

jab some starting fuld and misst the intake and all the lines if the idle dropps thier is a vac leak

bakomack

alright. im seriously at a loss right now. last night I plugged in my s300.

but for some reason if you would rev it to 4 the rpm would drop to 500 then back to 1500. so we set to ecu to a stock p28 base map and it was still doing the same thing. so I pulled the hondata off and threw the virgin p28 on and it rev'd fine. I think it has something to do with my tps not being calibrated. im fixing to light my car on fire

bakomack

anyone have any suggestions?

kp

You should deal with obvious problems before you move on to other possibilities.

You replaced the tps but never set it up correctly. You're throwing a code for the tps. Maybe you should think hard about this.

bakomack

I have, 1 I do not have a multi meter and pay day isnt until friday. I dont know anyone with one.

the best way I could adjust it is to let the car idle and adjust accordingly and then check it under load.

joelmatt89

yeah just try to be patient till you can get your hands on a multi meter, it is gonna be way easier if you have one, i agree with the previous post fix everything that you know is wrong and then if you still have the problem start messing around with other things you never know what seems to be something really insignificant can mess with things that seem completely unrelated.

bakomack

true, I called my boss and he says he has one at the shop so im gonna stop by tonight and if he does im gonna set it and get rid of the cel's. then we'll see what happenes

bakomack

last night I extended the wires to my 02 and plugged in (but left hanging) my IAT sensor. reset the codes. only throwing tps and vtec. cool

so I got a multimeter and had a buddy come over and adjust it for my. reads .5 closed and 4.4 WOT. we reset the codes. and then checked, em cool no more tps code. im ecstatic except for the fact its still idling at 2k and then 2 min's later it started throwing the tps code again. what gives?

bakomack

anyone have a an idea whats going on?

No VDUBS here in206

spray something around the im gasket and see if it bubbles, has to be a vaccum leak or o2. if its not either, it might be the iacv

bakomack

we sprayed start up fluid around the manifold and nothing.

I was told to check my fald idle thermo valve but my TB doesnt have one. so they told me to clean out my ivac tonight

bakomack

so last night I cleaned out the ivac, started the car back up and it now idles at 1500. its better but not right still.

then I put heater core hoses on so I could have a heater and hooked up my vtec lines to the ecu.

the tps is my last code. its been calibrated. does anyone have any idea how to clear the code and why am I still idling above normal?
