A friend of mine has a 96' civic ex coupe 5-speed and after we installed the skunk2 intake manifold the vtec doesn't seem to be kicking in, it gets loud but doesn't Bang in like before. The CEL "Check Engine" light is NOT on but the IACV is bad and the idle goes up and down... 1k-2k etc... Would that effect performance? What should we look over to make sure everything's operating as intended? Anything we might do to help the car out? we are using the stock throttle body and a 2.5" cold air intake... The 3" Short Ram seemed faster. Does anyone make 3" cold air intake kits for the civic? We have a Holly 66mm throttle body but haven't decided weither it would be worth it.... We might just pop it on there to see if it does anything for the hell of it.

THANKS

i have a 99 EX d16y8 5spd and is there any way to tell when, or if the vtech is kicking in aside form jus the feel?

 

You should Hear it KICK in at 5500rpm. Before the intake manifold it kicked in all the time, every time. Now it just gets loud and pulls after 5k but no VTEC kick?!?

 

wow thats the varible timing right there where it slightly pulls but gets louder, damn haha KICK in lmao ricers

 

lol, haha, It kicks but doesn't really pull much harder, the motors only making a little over 120hp like any d16. HAHAH FUNNY *** LITTLE DINKY VTEC MOTORS!

mine on my d16z6i can hear it and feel it i am useint the itr 62mm tb and an 3in short ram had an cai but just didnt feel right felt like it was starving for air oh and forgot to mention the tb bore on the skunk2 mani is 62mm so that is perfect and if i am not mistaken a new tune might help to but since he is obd2 i dont know what to suggest on that

 

..... either vtec engages or it doesn't. No CEL, than chances are everything is up to par.
