Alright, basically I've been dealing my vtec cutting in and out on me randomly.

Things that have been tried:

-Codes- I have none.
-Oil/filter change- recently changed the oil and filter, no effect
-Wiring - my wiring was done by Duane from Orlando Honda Acura specialists of Orlando, he's been doing swaps for a very long time and I doubt that's the problem.
-Vtec solenoid - Replaced recently
-Oil pan - Replaced recently.

I'm looking for anything else that could cause it to cut in and out randomly. Sometimes it works, sometimes it doesn't. This is on a b16a in a 90 Civic STD.

Anyone?

 

Bump.

It seems to work for a little while and then cut out after I've been driving for a bit.

Anyone got any ideas?

 

boost?

 

oil pressure??

Umm, kidding. There was a post a while back from some kid asking what wire to cut to get vtec. One of his requests was: "Help, I need bOost!1`"

lol i remember that post.shoulkd told him to cut the ingtion wire for vtec

 

ahh. glad you werent serious

 

i remember reading a post with the same problem and i forget what he ended up doing to fix it but if you say it works for a while then stops maybe your oil is getting hot and thinning out too much and your oil pressure is dropping. i think you need like 20psi for the solenoid to work. maybe im wrong though

This is something I'll have to check. Thanks. Any other suggestions?

 

could be the oil pump..check the oil pressure

 

sorry man i gotta say it......If you need boost, then get a turbo....VTEC is not boost, it is not the coolest **** on the planet, it is for GAS MILEAGE. And unless you are in it all the time, a non vtec has better bottom end power..

but im not hatin, i do respect the vtec, its just WAY overrated here.
Its much less of a headache to boost a no-tec engine.

I did see that kids post too, man that was great...lol

 

I had this problem one time and it turned out my distributor was going out. It would hit vtec fine for a while then it would just cut out and studder randomly....try a diff distb if you have one

where do you people come up with this "its easier to boost a non vtec motor" bullshit?

i dont know but its annoying...the vtec head alone you'll probably gain a shitload of power boosted with the flow difference..

Thanks for the help on my issue.. Like I said, I was just kinda making fun of that kid. I don't have any ideas about vtec replacing a method of forced induction.

 

Checked all your wiring? Sounds like it could be something loose? Try checkin all the connections....

Hmm, it doesn't stutter. It revs pretty freely, except when I start it up in the morning it tends to bog a little and then work perfectly. So I should check oil pressure, and my dizzy. Any other suggestions?

sorry, didnt mean to get your panties in a wad.....its less complicated to tune a notec vs vtec when boosted. thats all i was getting at.
sorry to thread jack there...

 

try taking off your vtec solinoid and there should be a little screen in the gasket. make sure that the screen is clean and not clogged.

Just adding this to the list of things to try once I have time. Any other ideas?

 

How does vtec help gas mileage. It allows all the intake valves to open at once thereby sucking in more gas.

I was saying mine also studdered sometimes also but it mainly cut in and out of vtec
