hi every one i have a 1997 ford f250 351 i swaped into a 1984 ford f150. my issue is it rolls coal like a diesel, i can not find what the problem is, it just had a complete tune up <embed width="600" height="361" type="application/x-shockwave-flash" allowFullscreen="true" allowNetworking="all" wmode="transparent" src="http://static.photobucket.com/player.swf" flashvars="file=http%3A%2F%2Fvid1320.photobucket.c om%2Falbums%2Fu540%2FStirling_Hubbs%2FVID_20140311 _132005_zps636cb982.mp4">

 

Did you transplant the whole EFI system or swap a carb on it?

 

everything its still efi.

 

that usually means its getting too much fuel, have you checked for any codes? there is also a small possibility the engine was only driven around town (doubtful being an f250) and is extremely full of carbon. how long have you let it run? does it do it at all engine rpms?

 

Did you transplant the whole fuel delivery system too.. tanks and fuel lines?

If so what is the fuel pressure at idle with vacuum attached to the regulator and with vacuum removed?

Is the O2 sensor installed in the exhaust and electrically connected?

 

Did you move the MAP/MASS sensor also?

 

yes it smokes all the time. the truck was a company truck, if i remember right a telephone company. i have no way to check the codes and i run it all the time

 

ya i transplanted everything. not sure about the fuel pressure yet
and o2 sensor is working

 

when u say move the map u mean

 

MAP: Manifold Absolute Pressure sensor.
It was mounted to the safety wall with a vacuum line and electrical to it.

 

sorry i dident work that right. i mean do u mean i moved it from the parts truck. the truck i used had a blown up 300i6 in 84 they had a computer with a carb and it had a map senor allready from the factory i just pluged my harness into it and run a longer vac line

 

You really need to check fuel pressure and pull the codes, by chance did you transplant the dash gauge cluster too? If not you will need to use a test light to pull codes. See the link for more info.. FORD 1983-1995 OBD1 Decoder

 

no i dident swap the cluster and i will take a look at it
