So, some of you have helped me as I redid my Throttle Body, Air Plenum and
Intake Runners. I buttoned everything up being very careful as possible to
check all connections. Got everything buttoned up to be able to run and
refill coolant and now the Van is running terrible. 84 1.9 with old style
vacuum system.

It is backfiring off throttle, if I can even get it off of throttle. No
Power when I do and get it up in the RPMs. It almost sounds like it is
missing on a cylinder when I get it up in RPMs. It also seems to come in
waves...so it will idle decent (though still chugging), then after a bit
will idle down to very rough and die. For the most part the worst of it
seems to be in the low RPM range. This is all while up to temp.

Few questions...I can still hear air coming through the Plenum. Is that
normal? Do you guys hear air in your plenum?

How tight should the connection from the Throttle Body to the Plenum be? I
am wrenched down pretty good but seems set and solid....not sure but want
to double check.

I did the propane leak check and didn't get any response from idle.

One thing I was thinking is that perhaps when I pulled the distributor cap
to check the vacuum workings in there I also oiled below the button.
Perhaps in doing that and coupling it with the RnR on the intake side that
the timing is now off?

Either way, sorely disappointed...worked for the past 2 weeks hoping for a
great running van and can't even make it out of the driveway!

appreciate the collective wisdom!
