My 81 ford f100 has a 302 engine. Im having trouble when i accelerate it acts like it is straining to accelerate almost like i have filled it with bad gas. I changed the fuel filter that is under the carb 7 or 8 months ago. could it be clogged already. do you have any ideas what could be the problem.

SOURCE: surging while driving

This is a notorious problem with the Windstars. There are oodles of ground straps in them. Make sure they are all clean and tight. ESPECIALLY THE STARTER GROUND STRAP. If it's loose, the car may just die when you turn up into a driveway or parking lot or just go over a bump. If you notice the "Check Engine" light comes on momentarily, at the time of the surge or the engine kills completely, it's DEFINITELY the starter ground strap! My engine used to kill at odd times -- even when on the freeway going at 75!-- Then we'd go over another bump and SURGE_O_RAMA, the engine's running again or I'd restart it and it would be fine for a while. What's happening is the loose ground strap loses it's connection when you go over a bump in the road. The next bump jogs it back into the connected mode, albeit tenuous at best. All of the computer techs couldn't find the problem. It took a 70-year old seat-of-the-pants mechanic to make the SIMPLE fix. It took so long to find the common-sense mechanic, however, that the down-shot of all of the surging tanked my tranny, which I had to have rebuilt! AND then, after I drove away from the 5-star AAA BBB "transmissing" shop, I found that THEY HAD NOT TIGHTENED ALL OF THE GROUND STRAPS! I took it back. They had no knowledge of ALL 9(?) ground straps and had to take it to THEIR mechanic who tightened them ALL down! It's been 5 years since then and I haven't had another problem with it. RULE OF THUMB: EVERY TIME YOU HAVE THE VAN SERVICED have them tighten-down ALL of the ground straps! If your mechanic doesn't know what you are talking about, go find a new mechanic. Generally, the AAA "Top Shops" are your best bet. They fix things right the FIRST time. I still haven't found a manual that has all of the ground straps listed, by the way.

pull the fuel line of the carby and turn the engine over to see if fuel is comming up
if the is no fuel then the fuel pump is gone

if you have fuel the carby needle and seat is stuck try tapping the carby with a hammer where the fuel entres the carby give that a go mate good luck

SOURCE: engine cuts out on acceleration

could be the pump or injectors or both. while your at it check your fuel tank for rust dirt any thing.

good luck

SOURCE: I have a 1982 Ford F100 (straight 6 cyl) that is

inside the gas tank there is a little round screen on the senion unit which is also the pickup line and fuel guage. take it out and get a can of brake parts cleaner and flush out the screen and then the fuel should go through that is about the only thing i thnk would be left since you have changed the pump and filter.

SOURCE: Ford-F350 7.3 turbo sluggish when you accelerate

i dont know about the turbo going bad,but i do know that ive seen 7.3 diesel have bad injectors,usually 2 at a time, check for fuel at the injector which can get messy so wear protective gear such as goggles and gloves,while running crack open the fuel line at the injector to see if there is fuel,it should run rough which is good on the working cylinders,if it doesnt change then maybe a bad injector,or not enough fuel pressure at that injector.injection pump issues are another thing,but most likely its an injector.
