This is part of what I think is more than one problem, so I felt I would start another thread - My 86, when cold, stumbles or bogs when the accelerator is pressed, this morning I disconnected the MAF connector, started the car and there was no bog when I pressed the accelerator.
My Bosh MAF rebuilt is about 4 yrs old I am hoping that there may be something else that is contributing to this problem.
Problem goes away when engine warms up (closed loop).
I have FIC bosh II injectors,
not throwing any codes (except when I disconnected the MAF)
new fuel filter .
TPS - .51 v
IAC - (reset as per forum)
tested EGR, operates under vacuum
Any Ideas?
Thanks Tom
