I need some serious help or advice here peeps,

2 days after having my sound system installed my vtec isn;t working properly.
here's whats happening:

in all the gears, from 5800 - 6200 vtec will kick in fine, then it will stop, my rpms won;t go any higher ther 6200 my car bogs as if its losing power, then it kicks in again going up to 7000 and at 7100 or so same thing happens again, it;s as if i have a rev limiter or something, car bogs and it won;t go pass 7100 even at full throttle no response, then vtec kick in again and i have power.

According to my vafc, vtec signal is consistently on, it never turns off even when teh car bogs and the rpm stops where ever its at.

I've checked, my oil level and its fine, also doubled chk my fuel and all and everything is ok...

I;ve done a search also but no concrete answers.

Any help will be greatly appreciated.

 

Sounds like whoever installed your sound system crossed the wrong wires.

 

Could be the stereo installation was done crappy, could be the VAFC with wacky settings, could be a shorting speedo signal. Could be alot of things you won't know for sure until a battery of diagnostic tests are performed.

 

Just a thought... How about reset the CPU by unplug the battery cable and reconnect it.

 

it makes no sense tho, when i drove the car home everything was perfectly fine. no problems. 2 days later this happened and I donlt know where to look.

I;ve also checked my vss connection and its perfectly fine. I don;t know what else to look for. if you guys have any other suggestions it'd be greatly appreciated

I've also resetted the ecu...

 

help?

 

Check your VAFC wiring. It could have gotten loose.

 

did that too, eveyrthing is secure

Agreed.

 

how do i do a battery diagnostic test?

 

I hate it when my VTEC runs out and you have to replace it.
Check your oil... didn't read the whole post...
check it again anyway.. its probally that time again.

did that once, then did it another time, oil level is fine.

help? in other posts, there are so many helpful h-ter's, where's everyone at in this post? I;ve done searches and have read almost all archived threads in regards to my problem but none seem to create the same symptoms as I am experiencing...

anyone help woudl be greatly appreciated...

 

check your VAFC ground wire,or use other ground!

 

i say oil...check it again and again

 

A battery of diagnostic tests includes testing every component of your electrical system,It is time consuming but this is the only way to source the problem. Dissconnect the VAFC, the software could have a glitch or the wires connecting it to the ECU could have a short or weren't installed very well. Get a code reader and keep it connected while you drive to see if the car is throwing a code when this happens, ECu can still throw codes even though the check engine light does not come on.

 

how about just remove the sound system and drive the type r like it's suppose to be driven - just with the bare essentials
