i have and 95 s14 with a redtop sr 20… i have been experiencing this weird bog from time to time… just in the transfer from vac to boost. ive checked all my intercooler piping for leaks found none. ive tryed a different ecu. my car has a walbro 255 lph pump. kind of lost as to what i could be… if you shut it off while driving and start it back up the problem usually goes away so i started thinking electrical. This problem is not constant just happens when ever it feels like it… possible that one of the coil packs is breaking down? or mabye a bad ground? any help would be great … because its not that fun to drive when it wont make power. thanks guys.

try changing your spark plugs and clean your maf it might fix it . it fixed mine

How is your fuel pump sending unit?

If it is rusted and shit, the connections may be breaking up.

I had the same problem back in the day and simply chaning the ground on the sending unit fixed the problem.

thanks guys ive changed spark plugs and also cleaned the mafs . the fuel pump sending unit ground sounds like a better explanation… where is the ground located? like where doese it fasten to the chassis? thanks again.
