My son is driving my 86.5 Hardbody V6 and he is having a strange issue. While driving at speed the engine will suddenly lose power like it shut off, then touch the accelerator and it comes back again. I seem to remember something similar back in the early 90's that happended to me in the same fashion but I cannot remember what the fix was. Might have been a throttle position sensor. Any feedback here? I just spent nearly a grand on a fuel injector and a MAF for the thing. It has been running pretty good for 260,000 miles (only about 1000 on a rebuilt engine). Thanks for the help
