i think im idleing too high...?
 

i have a b16a and i just finished changing the gasket for the exhaust manifold, i have a header, but it is like 4-5*c outside but i started it after not being started and it idled at like 1600 then after a rev it dropped to 1500, then dropped to 1250-1000 after it warmed up, is that normal for a vtec motor when its cold?:confused:

It's normal. My '95 EX, '99 EX and friends '91 Si all initially idle around 15-1600rpm at start but then drop slowly as the car warms up. Normal operating temp idle is anywhere from 500-900rpm for them and as it should be for these cars.

If you car continues to idle 1000rpm or above while at operating temp you may either need a mild tune up or simply need to adjust your idle screw.

Also make sure there are no loads on the motor such as A/C, headlights, etc..

ok thanks man, appreciate it, how long do you let your car warm up for? with a vtec

It doesn't matter that they have v-tec. If it's freezing or below, I usually wait at least a couple of minutes before going anywhere. If it's reeeally cold I'll take my time and let it warm up for a few minutes. If I'm in a hurry, I'll get going but I'll coast in neutral as much as possible and wont rev up too high until it starts warming up.

oh ok thanks for clearin it up, so like a good 5 min i take it?

Yeah.. 5 Min should be good..
Just look at your temp gage lmao. You'll see it start to move up

mine wont move till i move haha

Should be at 650 rpms when warm and anywhere from 1600 and down as it goes through its warm up

yeah im usually at 800-900 but my tach is off cus i have a b16a swap , but it sounds fine when it idles now

Why would your tach be off due to a swap? lol.
