Posting this for a friend...

He just got a 99 Si and the stock B16A2 except for a no name intake...it runs ok before it goes into VTEC but right before it goes into VTEC there is a loud hissing noise and you can really hear VTEC but the car goes no where...I had this problem in my Sol and I just ripped on it and it snapped out of it but I dont know whats going on with his car...We changed the Oil, Oil filter, spark plugs and I took off the VTEC Solenoid and didnt see any clogs and we replaced that gasket as well...any help would be great...oh almost forgot there is no CEL...

 

How bad of a ''bog''

Feel like fuel cutting off?

 

I'm not sure if its lack of fuel...it fells like its choking...VTEC screams but it doesnt pick up

 

the intake filter mite be clod....it happen to me...

 

check your oil pressure and oil level.

I'm gonna pre assume that his oil level is fine hence he just done an oil change.

Have you changed the fuel filter ever? Got gas somewhere you haven't before?

I can't duplicate the sound, but i'm sure if i were there i could help..

Maybe the VTEC solenoid?

 

just changed it
im going to make a clip of it so you can hear what it sounds like

 

Advanced the timing and nada...trying to find a OBD2 VTEC dizzy to see if thats the problem might swap solenoids...if it comes down to it...we will hopefully have a VID/sound clip up tomorrow...

 

Get the clip up when you can, but the timing needs to be stock and if you've advanced the timing depending on how much you'll need to run higher octane gas.

 

lol its not a bog... its more like the car has no power in vtec watsoever.. vtec pops loud just it doesnt go anywhere and hisses like there is a valve floating somewhere

I think the problem is your experiencing the powerband of a bone stock B16

::waits on video::

Goodluck bro.

 

Having the same problem as well with my b16a2 vtec is working but the car not going any where but this just started happening recently. About 2 weeks the car moved in vtec like my h22 accord bone stock in my hatch. Anyone that claims that a bone stock b16 has weak vtec has never driven a b16 that actually running good. Vtec moves hard in this motor when it working right. I believe my probelm is becuase I put to much oil in my car.

I'm preassuming your referring to me, Because i know i wouldn't be driving a b16 that's running right.. Because I'm driving a 12:5:1 built b18c1 & yes a stock b16 running right is still ******* weaksauce.

If you believe your problem is your oil being overfilled.. Pull the dipstick and check your oil level and drain some dumbass.

To the original thread poster, hit me up when you get the video!

 

Thats what B16A2 do, they are dog slow! Why I don't know? But every Si I have ridden in, felt poopish! Only thing I can think of is weight

Shut up.


That hissing sound is oil pressure. Either your car's not warmed up, or something wrong with your oil pressure. I had that problem.

4 qts of oil(5w-30)
Timing at 16
91+ octane
^^^Is all this correct?

What's the CEL for?

 

yeah thats all right
but the thing is, there is no cel
