posted all my problems on an earlier post 1990 eldo 4.5 bad miss
Well, got the care to pass emmisions.
Problem originaly___ bad hall effect and 4 injectors below resistance that was acceptable.
Then I failed emissions and checked the egr tubes at base of intake and they were plugged. Cleaned them out and nox went down to new vehicle specs.
Only problem now is a fast idle on deceleration. Tps and isc reset and all within specs, but idle stays high (1400 rpm) cruising at 25 - 30 mph. Have to use brakes and at 5 mph, it shifts down hard and idle settles down to 750 rpm as it should. Any one had this problem??
thanks
Denny
