cruise throttle surge

[1995 toad]

there is no line that sends exhaust to the intake, (pipe 50)_  that is why I posted the drawing to find out where you are working touching and looking, IDK, that.
The EGR path for Exhaust is:
1: exh port #4 , bored path in exhaust manifold. (no lines no hoses here)
2: then to the head drilling path (no lines no hoses)
3: then to the S path borings and welsh plugs in intake rear sections, no lines here, no hose.
4; then the EGR is closed or not, allowing this bored path to let exhaust to to all 4 EGR injectors, if car is late 1995 it has a SSD metal PIPE 50 that sends exh, up to the TB mono port drilling behind the TB, for mono port EGR injections.
that is how the EGR path works (not vac)


lets do pipe 50 , on late year 1995 G16B EGR class 2. cars,  seen like in Calif. first by CALIF CARB rules. and all 96 and newer have this 96/98
NOTE PIPE 50,,,     seen here I cover the mono port (pipe 50  is #1 clue) here.
Pipe 50 is the only external lines that run exhaust on any sidekick, mostly on 1996  up.  older are quad port 92-95 USA. This pipe is steel stainless steel and shins no rust.













the line (which one) that sends the exhaust to the intake manifold (where is this) from the egr (4 ports on it which one) does not seal at the egr when the egr is closed and sending no exhaust to the intake.
it should seal I would think.  (yes all parts do seal but NOT THE MOD)
please tell or show the part or end of part that is not sealing IDK ,  i do not know where speak of.

that is what I am talking about. that seems like that should seal when the valve is closed or there is a vacuum leak and idle problems when warm.. put another new valve in tonight. seemed sealed when egr closed... we will see what happens... does the probe signal the ecm that the egr is bad?  What makes the code get sent for the egr..
