read runs rough then quits, and function of fifth gear switch to see problems.
I tried:
rechecking and setting the TPS
checking the harness
checking timing
replacing plugs,wires,cap and rotor
replaced VAF Had an unknown good one
hooked up fifth gear switch
checking for vacuum leaks
check PCV valve
replaced O2 sensor $65
Ordered TPS $60
Tried or checked most of these things two or three times not necessarily in this order. must have done more checking but can't remember.
Never could figure out exactly how to pull the codes. The procedure in the haynes manual didn't work. The one listed here was from there and part of it was for OBD II no diagrams either. the haynes manual varied on wire colors for the 6 pin terminal.
Finally in desperation I changed out the ECM. Partly because after each thing I changed I "test drove" the car. The VAF was next to last thing I changed. Each time I drove the car problem became more frequent, I went from about 40-50 mi. for the problem to arise, to about 4-5 mi.
I said to myself, this thing is deteriorating, I have changed all the major components giving inputs to the ECM but the decline is steady.
The only thing left was the ECM that must have been dying.
I will test drive it further and maybe write back,
