Emergency Help Needed!!!
 

I just finished changing the rear engine oil seal, took a few days but I got it now. It's all back together.

PROBLEM: Car acts like I have the throttle floored whenever I start it.

HELP!!!!!!!!!!!!!!

does it rev to 3000rpm?
if so, thats just the accelerated warmup. put the car in gear when you start it to deactivate. otherwise you may have a vacuum leak.

check ur afm is connected, check that the thottle plates arent stuck open, check ur cruise control wire, there can only be couple things that would cause this, so just do a check.

one thing u could do, is have some1 start the car an u stand in the front of the car ready to close the thottle plates so it wont go to full thottle.

Bio: ........ what part of "throttle to the floor" would imply 3000 rpms???? Don't mind me, just supposed to be on my way to my girlfriends (5.25 hour drive) as we speak.


Still no luck more suggestions welcome (haven't tried them all yet either thought )

BTW, thanks to both

Did you mess with any of the throttle linkage.

nope, didn't touch the throttle linkage.

i think 3000 warmup is no where near being floored, and a vaccum leak wouldnt cause this, a leak would only cause bad idle or not to start at all.

correct me if im wrong, im pretty sure this correct though

rx7raca, you're correct. And since my car is trying to idle-race a ferrari, I don't think it's the vacuum leak or cold-start assist.

What is it reving up to. To the over reving buzz??????

well, I won't let it get up to redline, but it wouldn't stop even if I did.

Once before I was checking my water thermo wax pallet and I forgot to make should the fast idler cam was on. And started the car up and it redlined.

ok, the throttle body seems to be ok, I.E.: not stuck open, But that's the first time I've looked at it.

like i said check those things and get back to us. play around with the thottle plates.

another question is when u start the car, do u give it gas? because if u do, then maybe ur thottle cable is getting stuck or the plates on the tb. get back to us with some info.

And another ??? is the gas padel to the floor or what. Not trying to be a smart ass

ok, about the throttle valves, In the manual I'm looking at it shows the three in a triangle, which look ok to me, the move with the pedal appropriately. Now, what about the first two, there's two in the top positions, and an open spot at the bottom, and the two in the top seem to work in reverse, the are open and can move to close, but don't seem to work with the pedal at all. Also, nothing about them in the manual. Time to check the FSM

are you talk about the two throttle valves on the top. THat are towards the front of the throttle body. OR the back two

the two on top towards the front, they're open in all the pictures in the fsm but it never says what they are. Oh well, not important.

So the the other two on the top are closed and the one on the bottom

yeah, but the open with throttle like they're supposed to, can't test what happens when I turn it on though, noone here to help. It's gotta be some cable that got disconnected.

Now when you replace the rear engine oil seal. What did you take off of the car.

If I shorted the ECU, could it do this?

I am unshould about that. But I do not think it would. It probably wouldn't run I would think

anyone have a fuse box cover or picture of one? Or could anyone atleast tell me what fuse to pull to deactivate the Cruise Control so I can find out if that's what it is?

it woudn't be an electrical problem uless only the tach is moving and not the engine.

otherwise your TB has to be stuff open. without air it's not gona redline.

grap the cables and pull on them. does stuff move? if not it's wide open. should be a bit of slack in the cable. pull on the cable. it's not hard to figure out if it's open or closed

so let's see, you're telling me that if my cruise control got screwed up and it's trying to do 70mph (we'll just go with the last speed I set it at) then my car wouldn't redline?

Sorry, that's electrical problem in my book. I understand what you're saying though.

I've already checked the throttle valves and they look ok, I can't exactly check them though, because it won't start with the intake hose off. I'm guessing that because the AFM thinks there's no air.

do not think there is a cruise fuse. maybe wrong

damn, I can't find one either.

ok, one more time. I just started it up and let it do it's thing for a few seconds. It ran up to 7,000 rpms and stayed there, didn't go up further. By the time I turned it off it was blowing loads of smoke.

You may be burning up your cat. Does anybody know what would happen if he started the car in say 3rd, 4th or 5th gear?

What color smoke and where from

blue smoke out of the tailpipes. Probably just burning oil, it does that sometimes if I hit it too hard right after I turn it on. Hmm.... does this count as my car self-abusing?

Rice-eater: as far as starting the car in other gears, the car can only tell the difference between in gear (1-4), in reverse gear, in 5, and in nuetral. the 5th sensor is only used, i'm pretty sure, to know when to not light the shift light. Reverse is just used to turn on and off the reverse lights. As for the cat, I'm pretty sure it's empty but if not then I'm pretty sure it really has nothing to do with the problem at hand.

I am still stumbed. So you start the car up. It runs normal and then start the incease RPM to 7000. I am un clear of what you are saying

the cruise doesn't control speed with just electronics, it manually uses it's own throttle cable. so if it's throttle cable is stuck, removing it's fuse shouldn't change that.

well, it does need to have power to run that throttle cable. Just curious, it does run the normal throttle cable correct?

To reclear this up: When I start the car it acts as though the pedal is pushed to the floor and revs up to 7000 rpms. It seems to stay there but I don't wanna run it for too long. The throttle acts normal when the car is off. I watched the throttle last time it started and the only thing that moved was the ??? 2 front throttle valves???? so that's why I think it's got to do with Cruise. I don't understand what's going on though since those are always open and it would be closing them. I didn't see the normal throttle moving and I checked the plates and they didn't move without the throttle control moving.

The cruise and throttle cable are spread from each other

well, I didn't mean the cables themselves, I meant the pieces the cables are connected to that control the throttle plates. That's why I'm confused. How are the throttle plates not moving yet I'm running up to 7000. You think maybe one of the plates is off position?

If you push the gas padel, Does the throttle valves work normally

when the car's off. Yes.

when the car's on. Good question, running out of battery so I'll check later.

well sorry I cannot think of anything to help if I do think of something you will be second to know. I have to go do something else. Will try to check and see tomorrow if I can help. But good luck on figuring it out

Maybe bent spring or linkage in throttle assembly
