Ok as the title stated I've got a h22a civic and it runs great still dealing with axle binding issues hah. anyways on a cold morning start it starts right up but if I let it sit a while to let it warm it the car goes into limp mode and wont rev past 2k. I have to then reset the ecu and start it up and drive it right away. Im also having a nother problem that might be related to this. Also when I start the car the oil light is on and if I rev it up a couple times it will flicker and then turn off. If I don't rev it it take atleast 20 seconds to turn off and it wont come on at idle if im at a light or somethin. Vtec is weird too if im in third and go to vtec it engages at 5 or 5500 rpm and sometimes it will just go out of vtec like there isn't enough oil pressure. I've tryed looking this up and no solid answer. Would a fluctuating oil pressure issue cause the car to go into limp mode?

I havnt hooked up an oil pressure gauge yet.

Unknown ecu
butterflies have been removed
and its throwing a code 20 eld (eliectornic load detector)

 

ok i might have found out the issue. if this make sence. i check the ecu for codes and i pulled code 10 and 7 one is for the tps and the other is from the intake air temature sensor. and i found two tiny little vacuum leaks one on the intake to head gasket and a small on on the iacv. so what im thinking is that those leaks are screwing with the intake mani temp and causing it to throw off the iat sensor which would be throwing off the tps (which i just bought a brand new one so its deffiantly not that) and in turn screwing with my vtec. and all that could throw it into limp mode on a cold start up.

 

i doubt either of those two codes are because of your intake leak. they are completely separate issues.

did you calibrate the tps when you put it in?

 

Yea. First off i found out i had two plugs switched out for the ait sensor so i fixed that so no more code. Ive also fixed the leak from the iacv. So now when the car is off and i turn it to the on position to pull codes i get nothing. However as soon as i start the car i get a code 7 for the tps. Ive tried reajusing it but when I calibrate it I only get a max of about .38v and 3.7v WOT.
