I had did a swap to a 95 b18c1 in a 94 civic with the p72 ecu. I did all the correct wire changes for the knock sensor, vtec, EVAP, and somethan else and it idled high so i bought a after market 65mm TB with a calibrated TPS well that made it surge so than i turned the tps and it corrected the surge but than i was throwing a code saying there was not enough voltage to the TPS, i knew if i put it back where it first was it would creat a problem so than i hook up a lil extra power to it and it work great but still my rpm was about 1300 rpm warm and 1600 cold. well now i recently bought a Skunk 2 Intake and now the rpms are worse 2200 cold 2000 warm. I check every thing form cooling routing to wires to the ecu and vacums diagram and every thing is correct. i have cleaned the FITV and screwed that white peice in and cleaned the IACV but still nothing, i have tried to set the screw on top of the TB but the thing is the screw is it is all the way in. I have got all the bubbles out of the radiator. I had seen if the IACV had turned on with power and it does. i had let my car warm up and plugged up the bottom hole and the rpms did not go down but when i plug the top hole it goes to 800-900rpm which sounds good so is that the problem? i had taken of the IACV and i had no power to the IACV and than i had a hose that was corret dia fitted it to the hole with the screen and i could breath air threw it. hope someone can help. thanks

 

Search...thanks!

 

i got lost reading your post....do you have a CEL?

 

no cel for the IACV but when i'd put the skunk intake on i got a cel it was bout the o2sensor wiring being loose i cant remember the code# was.

 

i think code 41 is o2 sensor...not sure though..im thinking vacuum leaks...what tb gasket are you using? try to listen for leaks around the tb and im

 

ya I printed somethan off of this website bout what the codes mean, but i got the stock gasket on the tb. i will go and buy some stater fluid and spray around areas tonight. thanks

 

you hooked a lil extra power up to your tps??? you know it runs off 4.5-5 volts, right? did you use any gasket sealer on the IM/TB gaskets? too much? permatex? you should use, if anything at all,only a TINY 1/2 paper thin dab of hondabond on gaskets. it smushes all into where it isn't supposed to be... are you familiar with vacuum leaks? is the brake booster or hose leaking??

 

see i was getting a code that my TPS was not getting enough voltage but when i checked it it was .45 closed and than 4. somethan wot so i didnt get what was going on so i jump a wire from a know power to the TPS wire and than i was getting .75 closed and 4.7 wot and rpms were decent enough to drive but it took my cel away and i was able to go get my emisions done. but last night i bought some starter fluid and was looking for leaks and when i sprayed around the intake mani gasket the rpms went done so i went around the whole thing and sure enough that could be the problem, so today i am going to go by a gasket and put it on.

 

so your running a skunk2 IM and a aftermarket 65mm TB..shouldnt you be running an ITR tb gasket?

 

i dont know you tell me. what is ITR?

 

yea you should then...i have a skunk2 IM with an ITR tb and when i purchased an gsr tb gasket it would not match up to the itr tb so i had to order one..so try that...itr is Integra Type R FYI

 

nice well thanks. so i went and got a Manifold Gasket and put it on but than started it up and it was not corrected so now i sprayed in the same area and i think it is my injector o-rings that might be bad so i ordered some i will put them on today but ya i will go get a ITR gasket too, thanks.
