I have a SiR w/ a B16a, when I hit vtec it surges and the tach needle jumps around, I can feel it lose power but low rpm's are fine. Any ideas? I have checked the plugs, air and fuel filtes grounds and vacum lines. thanks in advance!

 

check your ground wires also what type of exaust system do you have

 

Sounds like a fuel problem.

 

Which ecu are you running??

 

Stock ECU and some crappy off brand japanese exhuast, If it is a fuel problem what could it be?

 

exhaust has nothing to do about it...


but yea fuel could b the problem either that...or ur not spark'in right...

i had the same problem...i jus changed my spark plugs and wires and cleaned my injectors and everything was fine again

 

The only reason I said crappy japanese exhaust is:

Will change plug wires and plugs and try again, thanks!

 

Try checking your fuel pump. It may be going out.

 

my friend had the same problem , and for some reason it was his dizzy, try another dizzy if all else fails ..

Ignore him, He's a homo.

lol Jk


Im just seeing if he is doing good on the forums, so far good

 

The reason i asked what type of exuast you have is because i had a dc cat back. but i kept getting pulled over so i changed it to some crappy stock type muffler and i bogged in vtec bad. Right when vtec came on it bogged all the way to 8grand.
