I have a b16a2 in a 94 hatch my idle speed idles erraticly between 1 n 2 thousand rpm's. I have no check engine light on but if I let out the clutch alil bit sometimes it goes where it should idle but if I hit the gas rt back to the crazy idleing can anyone shed some light for me?

 

I am having similar issues and recently found that I have a small leak in my head gasket. Hoses seem fine. I jsutfound that the TPS sensors is near impossible to get from a store and Honda wants me to by the thing with the throttlebody attached to it ($680)... sad.

 

I dont think its from the headgasket cause it would do it all the time and when I first start the car up in the morning it idles fine untill I hit the gas and then it begins but most of the time I can let out the clutch to drop the rpm and then it idles fine.Anybody else? The timing isnt rt on either could that b the problem?My new distributor is on order.

 

anyone else no somethin?

 

vaccume leak? do you get hesitation/loss of power while driving ever?

 

Have you calibarated your TPS? If it's finf get throttle body cleaner and that should do the trick!

try joe from locash racing, he usually has them in stock and it's a little cheaper. Here's the link to his online store.

Possibly a stuck open thermostat. My B16 jumps alittle and never really warms up all the way in the winter time, just too lazy to fix it lol

 

yeah i got a b16a and it has the same problem goes from 1k rpm to 2krpm. Takes long to warm up, the jumping up and down i was told it could be the air idle control

 

here this will help u noobs...most b16a's have a throtle body with coolent controlled idle air valve...well they are known to come out of adjustment soooo..if your is having this prob...look where the tps sensor is and just under it there will be the valve (its attached under the throttle body)anyways the side where the tps sensor screws in ...just under it there will be two 8mm bolt/screws it has a 8mm head and a phillps screw head ...take the screws out and take the plate off,when u get it off there should be a white plastic piece that came unscrewed..simply screw it bck in ..and not too tight cause its plastic..but b4 u do that ..what i do is wrap it with a little bit of teflon tape so it wont vibrate again...or lock tite.....put it back together and thank me later... have fun...

the motor has a bigger intake on it so there is no fit valve and its a standard transmission so I dont know if they have them anyways but when I first start the car n the morning it doesnt idle crazy

 

I have no loss of power everything else is fine I sprayed carb cleaner everywhere to chech 4 leaks and there arent none I dont understand the whole motor was rebuilt a month ago.Anything else anyone?

 

any 1 else have some info 2 share that might possibly work Its idleing irratticly between 1 n 1.5 and its drivin me crazy

 

bad grounds maybe?? is the ground for the wire harness to the thermostat screwed down nice and tight??

 

I have same problem. Let me know if you find a fix.

 

same here bro...let me know...ive tried almost everything that honda-tech has to offer and i stilll cant find the problem...so help me out too..mine happen after i put the skunk 2 manifold on..

 

Problem fixed IACV was dirty just took it off sprayed some carb clean on the screen then put it back on idles fine now

 

ive tried that and it still does the same thing...did i not clean it right?...any particular steps in cleaning it?....i need help!...when i changed ecus the car juss idles at 2k but when i put my ecu back in the idle goes from 1-2k..anyone?

 

adjust the TPS. There r 2 screws on the TPS (throttle position sensor) loosen the two screws and turn the TPS untill the car idles rt and c if that fixes the problem.

 

you shouldn't move the TPS without a multimeter to check the voltage IMO

</TD></TR></TABLE> this is correct but my idle was goin crazy and I just turned the screws and turned it till it quit. Maybe I got lucky. Anyways with a voltmeter u should have approximately .5 volts with car off (throttle closed) if not loosen screws and turn untill u do. Once u get it around .5 slowly move the throttle to full throttle and it should increase to approximately 4.5 volts. In the manual it says if the readings r incorrect change sensor (try to adjust TPS before u do that)

I changed the whole throttle body and tps....motor ran fine until I did a rdh conversion. Don't think mine is a part in need of replacement.
