- What's the worst that could happen?
I'm chasing possible vacuum issues and poor running. I've tried with some success pulling the vac lines from vacuum distribution block with the IAC unplugged. When I pull the trans vac line, the rpm does not drop as it should.
Pulling all the others results in a drop in rpm.
Sitting at idle, the rpm will rise and fall 1500 down to about 5-600 and eventually will stall. When driving at a steady speed, the rpm will suddenly just drop (almost as if the trans upshifted into overdrive -- but there is also a loss of power - no acceleration. Pressing to the floor to engage passing gear results in a total loss of power and soon after, a stall. Wait five minutes to restart and the process can be repeated.
I've been searching through the forum and found multiple other "things" that can cause these symptoms and am slowly eliminating them. This is just one of those things on the list.
Thanks and sorry for the long post.
