car runs fine when its cold but when it warms up at idle it lopes from 2k back down to 1k over and over. I was thinking bad o2? Im getting check ening light for 1 which is o2 and im also getting a check engine light i belive for 4ws my car is a 92 si non 4ws swaped a h22a into it but only ecu i could get that was a auto p13 was a 4ws jdm auto ecu. Probably giving the code for the 4ws as well. How can i disable 4ws function in the ecu or fake a pin out so it thinks itsworking cuz the lights gay. Also i was looking o2 sensors are pretty expensive anything i can do to get around swaping the o2 i know on mustangs if u buy a basani x pipe u have some way to plug the o2 up . Corect me if im wrong please if not whats a good place to get a new o2 sensor cheap?

 

I got you her even though im not the most knowledgeable. some people out here gotta agree. i had the same prolem with my old civic. the throttle cable is too tight just back off a touch. you will be fine. after that fixes it you can just hold the pedal a lil bit for a minute or two and it will lope again . as far as the rest of your post i cant help you

lol you lost me there bro ill check my cable see if thats the issue cuase i dont wanna spend 100$ on a new o2 sensor! Thanks for input

 

I would check the TPS and the IAC. When the engine starts reving like that unplug the TPS sensor and see if that makes a difference. You can check the IAC by switch your a/c on and off in idle. Your rpm should rise a couple of hundred with the a/c on.

 

if it doesnt make a difference then its my o2? My a/c was removed durring the swap.

 

You should also check the EGR valve and solinoid. another way to check the IAC is to turn on the rear defroster and the rpm should go up.

 

i did they looked fine.

 

What happened when u unplugged the tps sensor?

 

Could it be a vacuum leak?

 

Im telling you man thats it . dont know anything about the 4ws or check engine . after you loosen it a little and the problem doesnt happen again lets say for a week. next time you pick someone up or wait for someone in a store hold the pedal steady just take any slack out of it without really increasing the idle after like 2-3 minutes it will lope again then let gpo it will return normal. just basically got this one from expierience and just about everyone i know who mentiones this that solves it.

you have absolutely nothing to lose by trying it Its just a nut on the cable
