Possibilities:Timing is retarded,TPS (throttle position sensor) is malfunctioning.Make sure there isnt a vacuum leak(check vacuum lines and intake for whistling or air sucking)

What cause a sluggish acceleration on the 87 fiero


poor fuel pressure and or volume, poor fuel quality, ignition timing is off, bad throttle position sensor(TPS), dirty air filter, fuel injector/s dirty or plugged or not functioning properly, bad manifold air pressure sensor(MAP). just some things that can cause your problem. I would suggest taking your car to a shop to have it diagnosed unless you have the testing equipment and specs to know what is within specs.

Old '87 ranger been sitting in folks yard few years. fires up fine, but spits and sputters going down the road


Old fuel in tank, fuel filter clogged, plugged/clogged carb. or fuel injectors.

1. Drain fuel from tank and replace with new fuel with SeaFoam or Lucas

2. Repace fuel filter

3. With engine running at a high idle and air cleaner off, spray or pour carb/fuel injection cleaner into carb/fuel injectors.

If problems persist, check plug wires for cracks and/or breaks. Pull spark plugs checking for fouling.

2003 f150 supercrew 2wd 4.6 romeo has 62000 miles.Pinging noticed when thermostat opens after cold start.Pinging occurs with most throttle positions/loads except full throttle (cant hear it) or idle.EGR...


do not use any fuel additives at all. and only use 87 octane fuel nothing higher. 4.6 and 5.4 ford engines do have a pinging sound especially with a load. but it is normal

Fiero idles but stumbles on acceleration


to me this sounds like your ignition timeing is off because of the hard start and the no power when accelerating. I would definently check the timing out on it
hope this helps you out
