I did a minime swap on my car yesterday. Its a y8 headm z6 intake manifold, and the y7 dizzy. ill be gettin the y8 dizzy soon i hope. i put a p2p ecu in there. We wired the iac how the DIY said and even changed the pin on the ecu. but when the car has been on for a while the idle is super low and the car will bog out a bit when i push the pedal down. while driving, the car will rarely even pas 2k in first before it bogs out and starts makin a popping sound. thats when i stop trying and just roll it as far as i can. Were thinking its still a problem with the iac, but i read that it could also be and intake air leak somewhere. I need this car running asap. I cant get stuck lol. Any help is greatly appreciated.

 

What codes are thrown? The problem may be the distributor.

 

its throwing the iac, knock, and an o2 sensor that i havent had since i bought the car lol. i just bought a y8 intake manifold 10 mins ago. this thing looks direct bolt on. im even gunna have to rewire my iac to 3-wire again. i hope this fixes it all. if this fixes the issue of the car always boggin out, ill buy the dizzy tomorrow.

 

You also may want to double check the mechanical timing.

 

ill make sure to mention that. but its throwin the knock sensor only cuz i dont have one....and umm...what is that knock sensor even for or what does it do? do i need it? or can i just ground the wire like they said in the DIY?

 

It listens for spark knock and advances the ignition timing to prevent this potentially engine damaging problem. I don't think the sensor is absolutely essential.

 

oh ok. well ive been hearing you dont even need it. but now i know what it does. thanks a lot. i'll keep you guys updated with how it goes after i put in the y8 IM. im almost positive all my problems have to do with that.

 

ok let me break it down more to see what info i can gather. its a y7 block, z6 head, y7 dizzy, and z6 intake manifold, obd2 p2p ecu. the problem now is not the idle. vtec will pop and itll pull hard between 4500 and 5500, but then after that range itll just sorta stop pulling and just rev slowly. i ready that the z6 timing belt and cams have different amount of teeth on them. could this be a timing issue? and sometimes ill start the car and put it into gear and itll misfire when i hit arounf 1000 rpm. help plz!!!

 

get a z6 timing belt and also the y7 dizzy dont bolt up right to the z6 head you will need a y8 dizzy.

 

ill try that then...
