Last week I got the 7 out and ready for warm weather driving. Changed the oil topped off everything, killed the mouse and cleaned up behind him, replaced the e-fan relay, and new tires.
I still ahve the same flooding problem from last year, but now I also have an idle at 1500 RPM. I should be half that.
The screw on the top of the upper intake is closed all the way. the BAC adjustment is closed all the way. I can't get it lower no matter what I do.
Please help.

 

Hey mate,

Having the same problem here. Try checking for vacuum leaks since that's the most common one, also check TPS is within spec.

 

A mouse can chew small holes in vac lines. Inspect them all.

 

hanging up secondary delay throttles,, usually over adjusted nut on the delay mech

 

yeah my 86 GXL does the exact same thing, no matter what i do it idles at 1500 also.

 

Well, I checked the vac lines already. There wasn't much evidence of the mouse under the hood, only the left quarter panel. i will look more closely. I have a silicone hose kit sitting aruond. I guess I could go ahead and install that and see if it helps.
I haev removed lots of things like power steering and a/c, some of the emissions due to the RB header and block off. I also have the timing advanced a few degrees with the crank angle sensor, and an MSD 6AL on the leading coils.
If anyone else can think of anything that might help, speak up. I should ahve mentioned this is a stock keg in an 86 n/a. It's in my sig.

 

okay, heres the deal.
I went through and visually inspwcted each hose. I found no evidence os a leak. So i took some ether and sprayed everything that might have had or caused a leak. If anything happened, the RPM decreased instead of increased like it should have with the ether. but it was such a small increment, I'd say it's nothing.
I also noticed compression braking and decelleration is jumpy.
Anyone have any ideas?

 

PLEASE...
I need help. I'm driving this to Arkansas tomorrow and would like to have it tip top.
I know someone has some tips or advice.

 

I'll take a stab at it.

There is a sensor(?) of some sorts that can be adjusted. The adjustment is for decelleration. You basically have to make sure the ohms or volt reading = 1. On the turbo models you get the car hot then remove the TMIC. You then take a ohm guage and connect it to a plug. The reading should be set to 1. I read this from AARON CAKE so maybe he will chime in and be more clear as to what I'm talking about.

You can read about it in the FSM somewhere. Sorry I can't be more clear about this.
