Like it says, when i start the car it goes straight to WOT. From start up to turn off I hit about 2500 - 3000 RPM's and get a ridiculus spool from from the turbos (Non sequentual). I have tested the starter, it's workig right. No kinks in the throttle cable. Idel screw has not been adjusted from when it ideled right. Throttle cable responds with no issue to the peddle when puhed in. I'm pretty well informed with everything on the car. I'm going bald scratching my head here.

Any idea's?

 

Does this happen when you start the car in gear? The AWS will cause RPM's to jump to ~3000 on cold start, maybe this is some kind of fault relating to that? I don't know.

 

Blip the throttle. If the idle drops from 3k to about 1500, it's the AWS system working normally. I always blip it to bypass the AWS.

 

Car is not in gear at start. Excellerated throttle has been removed.

Blipping the throttle worries me a bit, because the rpms shoot up so fast. I'm worried about topping out the motor witht the turbos spooling the way they are.

The car has run fine with nothing like this ever. This started after tightening a fitting on the seconday fuel rail. Everything is connected the way it should be( check 3 times).

Keep um coming. thanks guys

 

lol is the throttle open?????? like the cable is kinked?? if not you have a huge vac leak

 

Thats normal, on your elbow from your throttle body theres a hose that goes into the elbow, disconnect that hose, vent it and seal both up and no more high rpms at cold start up, its a system that the car has, allot of people have this, its not a problem, mostly sounds louder when you instal a intake.

 

This has already been done to the car.

 

All vac lines are secured. This is what's killing me. I continue to hunt this problem down. With my luck, it's a lose lug nut. ( I know they have nothing to do with each other, that's just how things have been this week witht the car)

 

Ok, just a little background:

Did this just happen out of the blue? Or did you do some work on the car and then it happened after the work was completed?

Did you check the ISC and TPS connections to make sure they are on?

 

Yes this just happend out of the blue. Both connections are good. Car ran fine. I had a small fuel leak from a fitting off the secondary rail. I tightened the fitting, fixing the leak, Put the UIM back on and started the car. I have taken the UIM off4 times today checking everything possible. I'm now bald.

 

Same exact thing happened to me and a friend of mine last year with his FD. If you have another FD owner handy, have him (or her) pop the hood and check the position of your TB linkage as compared to one that's operating fine. More than likely your linkage (where the throttle cable attaches and the spring is located) is binding and causing the throttle plate to not fully close. Just grab the main linkage and turn it counterclockwise. You'll hear a "click" or feel a light "snap" when it comes unbound. Then lube it with some white lithium grease. For us, the solution was that simple yet we spent nearly two days trying to track down other problems. Check it out... it's worth a try!

Good luck!

 

Ok, I got it started and it idels where it should. Thing is; I couldn't tell you what I did to fix it. Thanks for all the pointers guys. I will watch for this again and make note of the reasob if I find it.

 

Joe,

Why didn't you call me on this?

I assume you were installing the XS power pack and this happened? I had the same thing happen a few years ago from leaning on the cruise control module and "kinking" the cruise cable. You were working in that area, weren't you?

Glad it worked out, but next time call me.

 

You are on vacation. I'm not bugging you.

Power pack didn't come in yet, so everything is /was how you know my setup is. That is why this was so wierd. Only thing I did was take the UIM off and put it back on. 5 hose connections, 9 nuts, and 3 connections. On the 5 time of reassembly, it started. You know I wouldn't post it on here if it wasn't something completely wierd.

 

maybe if your car wasnt stock it wouldnt be a problem glad to see you fixed your problem. im available for insight as well since my car has given me nothing but **** since i have had it

Its probably not wide open throttle. WOT would make your car bounce off the rev limiter. As far as my knowledge a whole lot of these cars do this and you just tap the gas and it drops to a normal cold start idle. Maybe i'm totally off the mark.

 

I wouldn't classify this as "Happening out of the blue" if you worked on the car/removed parts to solve one problem, you have deffinately created another. Out of the blue means the car was running fine whn I shut it off and when I went out and got back in t (doing nothing in between) it's not running the same. If you removed the UIM to tighten the fuel connection on the fuel rail then you've done something in the UIM reinstall to cause this problem. are you sure you don't have the throttle open with tension on the throttle cable or cruise control ? since you say the AWS is removed is the throttle plate stop seated against the idle adjusting screw ? There should be a very slight amount of flex in the throttle cable (not taught).

 

You checked the TPS, but did you check whether the voltages are supposed to be where they are. I remember my TPS was horribly off and it would idle at 3-4k rpm non stop.l

 

you know that happen to me saturday night I was crusieing down the freeway and starting to down shift. so I pressed in the clutch and the engine was idling at 3800 rpm. So I spent the next 4 hours looking for a major vacuum leak. after ripping off the UIM 3 times I notice that the set screw on the top butterflys had worked its way in opening the thottle just enough. But its good you found what was wrong.

 

It takes a lot of air for the engine to rev up to redline and spool the turbos in the process. That means you had a huge leak. That probably means the throttle was stuck open, since I can't think of any other thing that would cause such dramatic revving at startup (a few vacuum hoses won't be enough). So, your throttle stuck open.

It would be wise to see if you can figure what was making the throttle stick open, so that you can be sure it is resolved. It could be VERY dangerous if it happened while you are driving. It would also be wise to think about what you should do if it happens while driving. I would push in the clutch immediately and then shut the engine off with the key.
