Mike,
One way to test for intake manifold leaks is to pinch off hoses one by one =
while the engine is running=A0to see if=A0RPM decreases. You could also rem=
ove the each hose at the manifold an plug the inlet. Also be sure that the =
intake manifold gasket and throttle body gasket are sealing good and that a=
ll bolts are tight.

=3D=3D=3D JIM,

I will look at what kinds of adjustments I can make on the Throttle Body. W=
ow, that is low RPM!. I had no idea. Problem is I don't know what I don't k=
now.=20


>>> 1. Manifold leak - if this is the case it should be found and fixed bef=
ore any tuning is continued. Check all hoses and fittings on the intake man=
ifold and throttle body. Check that the throttle is closing all the way. It=
 may need adjustment. <<<

What technique do you use for leak detection?


>>>2. Idle setting on throttle body not properly set. If the throttle body =
has a idle speed setting
screw (allows air after the throttle plate) try to turn it to reduce the id=
le.<<<

I will look for that.


Thanks again
