so i went just had all my vtec things wired up right? Well i left and the vtec was tight and was really loud. No its kinda weak and not as loud. seems like something is restricting it to be pushing full potential Vtec.

Any body have some suggestions in waht i should check for or replace.?


thanks

sleeperrex

what motor do you have.....and wtf you mean you left it was tight and real loud then no its kinda weak

jdmdseries

ok lol D16Z6

i left the shop after having them wire my Vtec wires up.

it was working great, it was loud and noticable power gain

later tonight it felt week and didnt here it as loud, is there something i can do to get that strong and loud vtec back to normal.?

D16Z6... you cant really feel it on a D series espically stock...but do you have any CEL's being thrown how is your oil level? did you check the wiring again did anything get loose...

it might be that your o2 senser is bad i had the same problem with my d16 an i changed it an was back to normal but u can hear it an feel it on a single cam with an intake

pat92si

you have a single cam theres no hope without a turbo

pinky5

u pretty much arent gonna hear it...unless u have a cold air..u might...
but definately wont really feel it...
boost it....

VTEC is a binary system. It's either engaged or it isn't.

make your you have a good connection on your vtec pressure valve, if you are running obd1 and have a C.E.L it will show up as 22 ( 2 long flashes and 2 short) if you do have the check engine light on you can check by shorting the cable that is near the door i beleive it has a blue connector and only 2 wires going to it.

Check your oil

throw away that single cam.... you can make vtec noises with your window down that will be better noticed

Very helpful.

Us vs. Them

my friend has a stock b16a and his vtec kicks in like baby nuts...well you can't expect a single cam d16 to give you a kick in the ***..lol...If you built it up..vtec will kick in hard and pull you hard too..example i have a h22a fully built head..skunk2 cams and vtec is amazing..I'm sure you might have the wiring correct for the most part. otherwise ur vtec would bogg in and out or would not kick in at all...etc...so I'm thinking that everything is ok its just that ur expecting something pretty damn good from a SOHC..build it up..

when i had my y8 in my 00 ex, it had a greddy exhaust and only way u could tell that vtack kicked in was cause the exhaust got quite quick...

Beat me to it. Youre VTEC can not possibly get "weaker."

92nahatch

im sorry if i offended you im just saying that with a single cam you dont realy hear or feel vtec... as for my 13 sec run ... i didnt have vtec and i have an ls trans... no need to bring my car into the thread when u drive a d16 and i had a stroked ls-v... i hate all the hatters on honda tech and i am very sorry that my comment was well... sassy. i was just trying to say that the sohc vtec is not very noticeable... sorry

jdmdseries

its cool man just stickin up for myself.

thanks though good luck on what your doing

SOHC vtec is just for economy really so you wouldnt really feel much.

I do run a stage 3 zex cam and its nice and loud and you can feel it

jdmdseries

You act like weve been around hondas our whole lives and are the ignorant idiots that you find at the local ricer meet. We all know what a V8 can do and having a fast domestic is much cheaper than having a fast honda. Sure I could grab a cheap fox body mustang and make it haul ***** without much effort, but everyone wants something different. Were telling you facts. VTEC cant get weaker. Its either working or not.

B serious

The O2 sensor does not affect VTEC operation. The only reason that this might have happened to you is that your faulty O2 sensor was causing your motor to run rich. When you run rich, it usually drowns out VTEC for whatever reason.
