still running bad.
let me explain
had some sensors that needed replacing-done.
had grounds to refresh- done
had damaged wires-repaired
had low fuel pressure-replaced pump and filter
come back to wiring harness repair and had it working perfect 60 percent of the time. runs bad? wiggle engine harness and it comes back to normal.
replaced entire engine harness from a 90 XJ. I had 2 wires to repair from rodent damage, no other issues. opened carefully up and examined for any damage in teh harness along the valve cover area and the one splice there was in perfect shape, re taped and re wrapped. harness is in really good condition.
engine runs fine when it is right, runs weak like now when not. engine is not worn out and have not touched any plugs,wires,cap or rotor. have not messed with any other wiring or components. Just engine harness and sensors. it shifts up and down all gears.
it acts like it wont advance and deliver fuel . it also shakes like it has a miss at idle.
pulled plug wires one at a time and no issues. puled injector plugs one at a time and had the two middle cylinders swapped.
at wits end here.
