B16a idle issue
Whats up guys, i got a quick question. I think i know one of the reasons that im working on fixing but, i have a b16a with b16 trans swapped into my del sol. Its idoling weird as fuck though. I know that the iacv valve in the intake manni isnt hooked up and all the vacume lines are closed off, also i know that the o2 sensor in the exhaust isnt hooked up at all... i know that can be a cause too. It idols like at 800 most of the time like it should but it will randomly drop to about 500 and bounce. orrr it will be at like 1000 and jump to 1300 then fall back down to 1000 then jump back to 1300 over and over again. I thought it was a spark plug issue so i changed them, and one of my wires are a little fucked up. also with the idol it has a tiny backfire when idoling and shit too. any other ideas or anyone have the same problem and know the solution. im already planning on buying a new IM. so lmk thanks (dont hate im not a fucking god so im not sure whats going on)

Re: B16a idol issue
yeah I know about the iacv thing. But I'm saying on the swap there are lines that run from the IM thar don't go to anything, those are the ones closed off. And so I need to get wires too. Im new to a swapped car thats why I'm asking.first car with a swapped motor

Re: B16a idol issue
You've really answered your own questions. You have to get the iacv and o2 hooked up. You can't expect the ecu to do it's job if it can't get the info it needs to run the engine. Do those first, then move on to the vaccuum lines. Eliminate the variables one at a time. you'll get it. Good luck.
