hi i know these engines are a problem not that i have done many but this vehicle suddenly lossed power . ihave checked the manifold depression which is not that bad it is faily low when it starts to bog down and then wont go above 4000rpm .only data stored was p0170 .i have endiscoped cyinders and they are bad but i dont beleive would cause problem suddenly. since we have had the car here it is almost un driveable . checking fuel pressure with autodiagnos i have a reading of 0,35 hpa not one to trust what ad always says i tried jk100 and similar reading. at the fuel filter pressure port i have 3.5 bar, having limited info iwould have thought 35 bar plus through diagnostics for high pressure reading do these pumps have a problem ? any help apreciated
