My 88 trooper, no power, bogs on acceleration, idle dies out unless i give it gas.
I checked the fuel pressure and it was high 60lbs, fuel regulator not responding with vacuum applied. Changed regulator, now pressure is at 35 -
40lbs to spec, and passes vacuum test.But now idle dies out, runs worse. Could it be the EGR, seems like a vacuum leak?
I have the same problem.
Fuel pressure outside the injecter is 42.6 psi.
Vacuum lines have been replaced.
Did you find a solution to your problem?
