i painted my valve cover, and put NGK plugwires, on my JDM b16 swap, and since i did, my idle is staying up at around 2000, i have the idle adjust screw tightend all the way it can be...and ideas?

 

Put the idle screw back to normal for starters. Did you take off your intake or unplug anything when you did your valve cover? Is your throttle cable super tight? Are there any kinks in it?

 

did you put the PCV valve back on?

 

yes everything is back...this isnt the first time ive taken the valve cover off lol...just looking for ideas, tha ti havnt used yet...

throttle cable is firm, not tight, car was running perfect before

has skunk2 intake manifold, hytech header, aem intake/filter,

 

Sounds like a vacuum line to me. I did something simular on a b18b I had a while ago. It ended up being a vacuum line I had overlooked during a swap.

Go look at your IM and inspect it for lose/missing vacuum lines.

 

check all your vacuum lines and your TB for leaks because I just had this problem with my GSR.

 

I have a b16a3 and it idle's at 2000 too when its cold..... is this not normal ?

You're kidding right?

 

well this is after driving around like all night...ive gotta put in a new axle tomorrow, so im gonna look over everything really good for about the 5th time i guess lol

 

93eg2james I am not kidding when its warmed up its at like 1000.

ps: I have a 95 del sol vtec if that matters.. Also could it be the gas I use ? I use the lowest octane which is 87 here..

 

its normal for you, jit

 

Yeah, its normal man. I really did think you were kidding. There is this little thing under your TB called a Fast Idle Thermo Valve, and thats what controls your idle during the warm up stage. If you want to adjust your idle after the car is warmed up, there is a screw on the top of your TB.

Del Sol VTEC I have a 93 Del Sol Si (b20vtak powerz)

 

thanks 93eg2james you got my worried for a sec..

ps: is it bad to use 87 octane ? its the lowest octane/cheapest gas here..

haha I just replied to your PM. 87 octane isn't very good. It burns much quicker then higher octanes and leaves your fuel system dirty, and produces more carbon build up. You'd be much better off buying decent gas as it will last longer, and prolong the life of your car.

 

Thanks man everyone I ask around here just says "its all the same **** don't worry" guess I am gonna start using 91 now.

really???so that means better MPG...i remember reading a thread about how the octane does give you better HP and that the gas burns at the same rate....can someone else besides 93eg2james clear this up me???

No, no, no. Octane ratings [only] measure how resistant gasoline is to preignition. That said, you only need to run 91 if your owner's manual says you should or if you've built the engine for high compression, boost or nitrous. You should NOT run 91 octane in a car that does not require it, as you'll simply be pissing away money.

No, you do not get better gas mileage from running higher octane fuel. That is a myth and nothing more. Octane molecules [C8H18] do not give you more power: they simply allow more power to be made more safely, aka, without concern for catastrophic detonation/preignition.

 

Ok so am I supposed to run 91 octane ? I have a 1995 del sol vtec it has a b16a3 motor.

Yes, the B16A requires 89+ at a MINIMUM. If you ever rev the **** out of it, I'd stick with 91+ to be safe, as the compression is rather high and the timing aggressive enough to do damage at 9000rpm if you misshift

 

ok thanks will it also make my car run better ? it runs really good now but just wanted to know if I would see an improvement ? I have been using 87 octane for about 3 months now..

thought so...
i knew what he said was not true but i didnt know exactly how to correct him....but yea...what archidictus said is what i've read in other threads..

 

can it leak though the valve cover?
