hypertech module problem
I have a 1990 ford f250 4x4 it has a hypertech module
and it says hypertech on the ecm it has headman headers
and less than legal dual exhaust it also has a msd blaster
coil and K&N FIPK my problem is that it was in A major accident
and I put it back together (most of the front clip) and now it
runs realy rough and realy rich (it bellows black smoke when you
give it gas) I do not have a whole lot of experience with efi
and any help would be great thanks a million CHEVYSTOMPER

hypertech module problem
Open loop basically means its operating just like it would at WOT because its not getting all the sensor inputs. Finding the bad sensors and correcting it is the solution.
