Crossfire injection troubleshooting. Surging Idle...
Having a few issues getting my 82 to idle properly. I was hoping that someone here on the forum could help me out a little but seeing I feel like I am at a dead end
Got the car, didn't run or drive.
Replaced the battery, fuel pump, fuel pump sock and little connecting tube on sender unit, replaced fuel filter and one injector.
Now the car runs
but wont idle properly. Surges.
Replaced original spark plugs and wires.
Redid the top plate gasket, TBI gaskets and replaced the MAP sensor.
Seems to run better.
Will idle nice for around thirty seconds, high at first, and then as idle decreases it then goes back to its old habit of surging.
No check engine lights. Already plugged off vacuum at the main port on the rear of the manifold (to headlights and cruise) no change.
How bad would a broken egr soleniod connector make the idle? Do you think its s problem with the ECM?
Thanks in advance!
