My ford is a manual 5-speed trany. When i put strain on the motor it feels like it cuts out. It doesn't do this every time. I have taken to the shop nobody could tell me what is wrong. I have put new plugs and plug wires in. Made a difference for about a week or so then went back to the same thing. I need help please

what kinda -STRAIN - are we talking about ? most of the computer motors have a REV. Limiter in then an if you wind her out to tight , The puther will start cutting out the injectors.... other things possible bad fuel pump getting weak an cant keep fuel pressure up ??? , fuel filter ???,, something floating around in the tank an under hard Accl. it gets sucked up to the tank pick up tube cutting off the flow of fuel ,,,, the wiring harness to the cam sensor on some models wear through an chaf, on the brackets up above the water pump area to the coils,,Seen this on some with bad motor mounts an allows the harness to shift an short out breifly--Any one else ?????Coils breaking down ??.

i tried a new fuel filter also. Taking off in second gear or taking off up an incline no weight on the truck at all. It seems be more at low RPM like when you are taking off. By the way thanks for your time and help. I'm going to try a new ignition coil next if that doesn't work i will start with the fuel system.

I have also heard bad things about this motor 4.2l what do you think? My truck has only 55,000 miles on it and from what i have read makes me a little nervous to keep it.
