I am still trying to figure out the issue with the car, I was talking about this under another thread regarding testing fuel pimp output but I know think my fueling is ok. the problem is anything over 16psi or better the car just noses over like you shut the key off, my initial thought was a fueling issue but I have plenty of fuel under WOT my o2's are 780 or so.... I am now wondering if my spark is falling off under higher boost. Up to 15psi the car runs great and pulls hard but over that and it is done, I have zero knock so I am thinking coil pack or module.
I pulled my plugs the other day and they do look a little on the lean side as far as color. Would a weak spark generate a lean look on the plug? I would think a weak spark would give me a rich condition due to unburned fuel in the cylinder.
I did have a burned ground wire that had corrosion, could that bad ground have caused either my coil pack or module to go? Just trying to figure out all possible solutions before I start changing parts.
By the way the car acts it is something that is affecting all cylinders at once, as soon as it hits 16psi the car is done and it just sounds like pistons moving air with no spark , of course as soon as this happens I lift so trying to get a good grasp on what is happening is a little difficult.
Ideas please........
