Engine miss problem
I have an 97 F150 with the 4.6 engine. A few weeks ago, I had a problem with the engine missing a bit, especially when pulling a pop-up camper, with a pretty good load of gear in the bed also.
Ok, I changed the plugs, using Motorcraft Platinum. I still had a problem, so after dark I check the wires. That was kinda cool following the spark around the engine. Replaced and all seemed well for a couple of weeks.
I get in the truck and start towards the city, and the truck starts missing badly. I stopped, checked to see if a plug wire had popped off, but nothing was amiss. After a couple of miles, it started running smoothly again. Wierd.
Three days ago, it came back with a vengeance. I checked plugs, wires, injectors, cleaned the MAF sensor, and nothing was coming up. I was going to check the EGR today, but the daggoned truck is running great again!
I am wondering what to try or look for when it happens again, because I am sure it will. I'd hate to be towing the camper to the lake and this starts up again.
