strange fuel/injector/ignition/ecu problem???
Ok just i was cruising around and my car was driving really well. car felt extra "smooth" during power delivery tonight.
On the highway, all of the sudden my car read super rich (pegged at 10.0:1) and when i put the tranny in neutral, gassing it wouldn't help and the rpms would go down... luckily i put it back in gear and the rpms would come back up, but would be at 10.0:1
i had to pull over wait to i completely stopped then restart the car and the problem went away....
stats-
built d16y8
neptune rtp
distributor king distributor
rc 650cc injectors

Re: strange fuel/injector/ignition/ecu problem??? (igo4bmx)
are you using the fuel cut delay slider tool in the newest version of Neptune?
I was having a similar prob with some fuel spike on decel, which would quietly bog my car down and sometimes kill it. Give the slider a shot if you havn't already, it solved my prob.
