i have a 97 f150 with the 4.6 in it. ive always had a rough idle at times but ive never tried to fix it. the other day getting on the highway the truck would jump from 1500 rpm to 3000 rpm and jump back down and did it prolly 3 or so times.
this morning goin to work i started it up and turned just the blower motor on and it killed the engine and now it wont start. ive got a new tps sensor that i got for cheap but i know thats not the only issue. any ideas on were to start lookin for a short or ground would be great. thanks

 

Welcome to the site but, this isn't the right place for your question... going to move this down to 97+.
