hey guys, for some reason the bronco now wants to die when coming to a stop. we had our big trip April 12-14..starting on the 15th i started to notice the idle dropping every time i came to a stop. normally it would hold a 1000-1100 rpm til my speed dropped below 8 mph...its not doing that any more either. if i gear down it will stall out every time...so now i have to ride with clutch in or slap it in neutral and pop the throttle once and it will then hold its set idle. ive also notice it wont do this until engine come up in temp...if i start it up and go...i can make a few stops before it starts stalling out.
i was sure the VSS was taking a dump...so i swapped it out. i had another laying around. but its made no difference. a month ago i set the tps voltage and idle and none of that should have changed. im still running the A9P(which i thought was not dependent on a vss)
fyi, i did install cruise 2 weeks before that April trip...only putting that out there. it was a simple wiring hook up and it gets its signal from dakota digital cruise output (at 2K pulses output) ...plus i run 2 ford vss, the 1st one at the tcase is for the EEC and the 2nd is for Dakota Digital...so neither of the systems should know the other is even there.
if any of you have some thoughts...lemme know. this is becoming annoying to drive now%)
