Please help.....NOW!!!!! (56k warning)

[TheMajesticking]

I broke off the nipple on both valves near the FPR. The valves would cost me $90 to buy new. I talked with Toysrme and he showed me how to bypass these valves and gain a bit more power. I took his advice and it's been about 3 weeks since the mod. 2 weeks ago I ran 1/3 can of seafoam through my booster line and a full can through my gas tank. Yesterday I started noticing that my car is cutting back like I have a vacuum leak or the car is getting gas and it is being cut off intermittently. I have no clue what this could be. I went to my local mechanic and he looked at the setup like "WTF did you do?" I was like "I took some advice from a guy to save myself some money". He was pissed. He ran a couple of vacuum lines and put them where he thought they should be temporarily. When that didn't work he recommended that I go back to the factory setup. If I don't get any help then that's what I'll do.

Cliff notes: Bypassed EGR. Car cutting back like it has a vacuum leak.

I took some pics with my phone of the current setup.






The valves that are broken:

Toysrme's Setup: (hope he doesn't mind these pics uploaded)



Please

[terrastrife]

do you have a vacuum leak?

[88 LE]

2 of your VSVs are missing a hose.

I circled them in red, in the pic below:

I did realize that but I was told not to worry about it. Could this be a reason? Would I feel a difference a whole 3 weeks later? I dont feel any suction coming from it.

[Toysrme]

No that's not it.

Give me 2 min to paint it and upload it.

*edit* - Answering




****************************************






The missing coolant vacuum hoses don't have any bearing on anything. None of the four are even needed, nor will anyone in any normal climate percieve any differance in running.







There are two (four seperate) problems:

1) Both of the VSV valves are connected to vacuum (remember we're no longer using them)
2) The ECU is still connected to both VSV valves


When the ECU starts pulsing the FPR (blue/teal/green depending on age and color fading of the plastic) VSV It creates a vacuum leak.
When the ECU opens the ACIS VSV (red/orange/brown depending on age and color fading of the plastic) to close the ACIS valve, it creates a second vacuum leak.





See how I just took a 3 " piece of vacuum hose and bent it to both of mine? That's just a free way to plug them both (two equal vacuums can't leak anything)

[TheMajesticking]

Ok. Look here though. Look at how I had it set up at first. (5th pic). I have a vacuum tube going in a "U" to both of those openings. The problem arose today with it like that. I changed it to the other just today because of it. Could there be another issue.

[Toysrme]

OK. That's still wrong tho Think about it. Every time the ECU opens those vacuum valves, you're sucking vacuum anyways.


But to the other issue then, interesting. What did we wind up doing to the vacuum tank?
Did you plug the vacuum line that feeds it?

[TheMajesticking]

I didn't touch anything other than what you see on the screen. I pretty much only messed around with the hoses around the throttle body and the hoses around the FPR. Could this be why? So I need to cap those openings where I have the "U"?

[Toysrme]

OK we'll get back to the vacuum tank in a min.

Definately plug those two vacuum lines going to the VSV. Every time the ECU (which happens to be "vehicle out of park", 50% TPS, 4000rpm or greater) The ACIS valve opens, causing a vacuum leak there. The FPR VSV opens as rpm increase. (I forget at what point tho)

So that's two vacuum leaks just caused by the ECU opening those valves.

[TheMajesticking]

Oh. Ok. When I go out to the car I will do that and see what heppens. I will update afterwards. Thanks Toys.

[Toysrme]

Anytime.
The vacuum tank (under your battery where you got that spare, long vacuum cable) If it only ahs ONE vacuum hose going to it, cap that too.

[TheMajesticking]

Ok. i just checked this morning and noticed that there were TWO hoses coming from the vacuum tank going toward the FPR. I took them off and capped them. It still ran like shit. It didn't start acting up until the car heated up real good and I floored it. Once I floored it, it took off, and then right after it shifted into 2nd gear it started sputtering and dropping power intermittently.

EDIT: I forgot to reset the ECU. Could this be why?

[TheMajesticking]

Here is a pic of the vacuum lines that I capped off. Hope I was supposed to:

[Toysrme]

Ohhhhh kay, I've had enough of this shit...

Bare with the color coding... I kept changing my mind.

[TheMajesticking]

FYI....

Ok. Thanks B. I will try it today. As I've been telling him...The car is running perfectly for the first 30mins of driving.. After that it starts cutting back really bad. After I do this I will update and let everybody know what happened. Thanks again Toys.
