How-To: VTCS Removal and Porting

yeah and each one has a specific direction it should be facing when put back in!!!!!!!!! just check the owners manual. but defiantly need all three
 
ill try to check these... but they are probably already there. i know for sure that i changed the green one, going to the engine*.

but if there was a leak, i would be all time, not only when i start the car?..%!!"$"
 
How cold is it where you live and what is it like when you start it. My car never drops below 900 when cold and in gear. In Neutral it is around 1000-1100rpm. And when warm its about 700rpm.

well if the car is not heated, if it hasnt been used for like 8 hours or so. its like 15 outside, but it happened when it was 25 outside also.

when it starts it goes at like 2k, then it drops to 500- or lower - then it goes to 1.7k.

if i put the gas to the floor when it starts, the engine drowns, IMO : too much AIR, not enough gas.. the car also hesitate when its cold outside, after the startup.

after like 2 mins or driving, its normal, idle at 700-800. STABLE, 100% stable( i ve had egr problem in the past with my older protege i know what its like)

maybe theres a problem with the header manifold, not letting enought air go through as its not hot enough, or maybe not enough gas coming out from my injectors.


:S :cry:
 
Yea that is much colder than what I have. For me outside is like 60 degrees. I guess I can't really figure out whats wrong without seeing it.
 
*puts up defenses from tuning geeks* i think whene your engine is cold it runs off a closed ecu mode... so it still sounds like you have an air leak. cus when the engine hits proper temp your ecu will have an open loop and then compensates for the increase in air to fuel ratio.. maby. im also going off you stating no cel, so sensors should be all ok. there isint all that to much o go wrong here unless you fuged up an injector. in wich peolpe should not scare from this mod its simple and worth it!!! (for me it was free)
*wating to be corrected*
 
well i had to play a lot with my injectors since all the oring in them were broken.

and btw when i say 15, 20 or whatever, thats in C, not in F.
 
how do you clean your injectors?im scared about removing them and having the orings chunk again. mazda sold 4 orings for $20 lol. $5/each oring thats a pain in the ass

anyways, tell me it might be the problem. :)
 
since I've installed my vcts intake manifold my idle has been ****** UP. It idles normal, and then the rpms suddenly drop and the car almost stalls. And comes up to the low rpms again. And it does so randomly every 10 seconds or so at idle with the car fully warmed up!!! Everything else on my car is stock again, i ******* put everything back to stock, trying to figure it out. Its the intake manifold or something to do with it. Help guys?
 
Any CEL when this is happening?

It sounds like a "simple" vaccuum leak to me. Check your lines for cracks if you're sure they're all connected.

yeah i checked all the lines, i threw a CEL the other day that said "too lean" I took off my injen cai and it hasnt come on since though... The car is at the dealer, i've got 700 miles left on the warrenty, I figure that I'd give it a shot
 
If you aren't doing anything this sat come to a mini install meet this sat. I will try to fix everything for you. But you will need to buy new gaskets and the dremmel pieces just incase.
 
you lucky guys :S. i havent fixed mine yet.. im sure that putting an mp3 ecu will give more gas on startup and will fix my too lean problem.

when i start the car it stalls the 1st and sometimes the second time.

too lean. :S

I might just do that man, we'll see what the dealer says first though... its still in the shop... I'm 4.5 hours away right now at college but if that is what it takes to get my car running right then so be it.
