Just Got A MK3

Awesome. I will check it in the morning to see if it works or not.

Is the ISCV in Toyota Celica's as well? If it is broke than I don't want to have to buy it new when my local junk yard might have it! They don't have any Supra's though.

I know that the BVSV is in a Celica so I plan to get that tomorrow from U-Pull-It.

So if the ISCV clicks that means that it is working, if it doesn't than that means that it is broke or jammed correct? If it is jammed how do I fix it after it is removed?

Was looking under the hood this morning and noticed that 2 things weren't plugged in..

Don't know where they go to but Im planning on going to U-Pull-It tomorrow to get a BVSV out of a Celica.

EDIT:
Just got done checking the ISCV and after I shut off the car it clicks 4 times and than makes a FSSS sound. I am guessing that is good and that it is resetting itself. Tomorrow I'm hoping to get a BVSV and see if that fixes it.. if not I guess that I will be checking hoses all day..

Those plugs you have in the picture may be for options your car doesnt have. Mine had those unpluged and didnt have the surging issue like yours does. The ISCV is a better bet for the problem, they arent a no fail part none of the parts on this car are no fail just replace it they arent too expensive. As for the FSSSS when you shut it off check your vacuum lines sounds like one is in the wrong place.

Damn... put a little more time into the sentences SD... not making a whole lot of sense there.

The black plug below the battery may be the connection for the small electric aux fan located beside the primary fan.

The white ones by the cruise control actuator appear to be for turbo functions... odd you'd have a GTE harness there though. One would go to the stock boost gauge sender and I cant recall where the other goes.... been a long day and my head's not entirely in the game.

The only other vehicle that I know of with a compatible ISCV is a 7M-GE equipped Cressida (looks kind of like a Camry).

BVSVs are very basic devices... as long as the threads are correct just about any BVSV off of a similar vintage Toyota should work just fine.

Weird.. the guy that I bought it from said that he did a rebuild on the engine but I still don't know why it would be there if it wasn't a turbo..

Anyways I plan on getting everything done tomorrow. Hopefully replacing the BVSV will do the trick. If not I will check all of the vacuum lines with Carb cleaner or whatever you use to check.

The only thing that doesn't make sense to me is that the car ONLY does it every once in a while. When I bought the car we drove it for 2-3 hours home and it drove just fine, I drove it all day the next day and it worked fine. Than the night after it drove with the revving, the next day it was gone. It revved up ALL day yesterday and I started it today and it ran just fine..

I don't see how if there is a problem that it just happens sometimes. You would figure it would effect it everytime.

I don't think that the ISCV is broke, I heard it click 4 times when I shut my engine off so I'm not going to replace it now unless I need to. I think that the FSSS sound was it resetting, but I'm not sure.. if that FSSS is from a vacuum leak than it should be easy to find.. I'll just need a partner to help listen for me while I shut it off or vice versa.

Update:

So today I checked more into the ISCV to make sure that it was working properly. Unplugging it and starting the engine made it idle at 2 rpm and when plugged back in it ran at 1 rpm so I know that it is working correctly.

We sprayed down the hoses and didn't notice any leaks, the idle never changed when spraying over them.. so now I am lost have no clue what could be going wrong.

The car ran fine today as well.

When the car is off does the vane in the AFM close all the way?

Does the throttle plate close all the way?

Have you checked the intake piping for cracks or holes?

Have you checked the timing?

Any error codes?

Sorry if you've already been asked and answered some of these... I just can't keep track of everyone's problems right now, so please just bear with me and repeat your answers.

BTW, it's 1,000 RPM, not 1 or 2.
