guys I need your help again! My damn secondaries are still not opening after finding a vaccum leak. Well what could it be an actuator or another vaccum leak? If another vaccum leak, how can ford locate the leak? thanks a million

They must be stuck closed, because the deenergized position of the secondaries is the open position. Did you disassemble the intake recently? I think you could get them jammed if you didn't put everything back together correctly. Remmber, engine off and above 4k rpm secondaries open, 0-3900 rpm they should be closed.

I guess I misunderstood you. If you can move them by hand, then I would keep looking for a vacuum leak. There should be a vacuum supply, make sure you have vacuum suppy there. Also, make sure both of the runner butterfly actuators have their vacuum tubes connected. Probably the best way to make sure you are connected right is to compare your car to another SHO. After you make sure the vacuum is routed right, then check the electrical circuit.

Good luck,

Good grief! Learn some forum ettiquette, will you?

I posted a detailed diagnostic procedure in your previous thread about this exact issue and here you are yelling and screaming for more help in a new thread with a topic of "HEELLP!!".... squint squint

1) DO NOT start new threads to continue a previous issue unless the previous thread has become unmanageable.

2) When opening a new topic, include something in the topic that actually relates to the issue at hand.

3) Don't blow off my efforts to help or you'll end up on my "Ignore" list. Then I will never see your posts and will never offer assistance to you. If you do not understand a procedure, just ask, it will be explained as well as possible.

I think I'll go have a beer...

projectSHO89's right.

So what is it? Are the secondaries closing when the engine starts? Are they not opening at 4,000 rpm? Are they not closing at all? They are closed by vacuum from the intake and opened at 4,000 rpm by the EEC actuating the electrical solenoid on the vacuum accumulator to release the vacuum. If they are not closing, you have a vacuum problem. If they are not opening, you have an electrical problem. If you can't move them by hand, you probably had a backfire and folded the butterflies around the pivot shaft. Don't laugh. Artesia did just that to his poor SHO.

well, as you can probably tell I am very new to the sho forum (forums in general for that fact). Sorry about posting twice. You guys are a big help and I appreciate you guys. sorry again. frown
