hi, have you checked the tps sensor ?
are you getting any check engine light and if so are there any codes ?
have you done a compression check on the motor ?
check that -I will always do this just to make sure that the motor is good .
try disconnecting the connector from the tps sensor (throttle position sensor) and see if that helps things ,you may feel hesitation from disconnecting it but this is to see if the motor runs better and doesn't feel as it is running out of fuel .
it may also be that the timing jumped a tooth or two-that will give you low power/feeling like it is running out of fuel etc..
Also, do you have good spark from the coil to the dist cap and from the dist cap to the spark plugs ?..jazzmaster ..

Did tps check. no difference. Did compression check. Was ok. Codes from check engine 21-22-24-29-11. Haven't checked to see if timing jumped a tooth. Will try that next . Thanks

ok, make sure about the spark as that will rob a lot of power ,take note of the codes ,clear the codes and then run it again to see if the same ones come back please ...thank you

Hi, Checked the spark and cleared the codes. Same problem and returned same codes. I'm going to try pulling the fuel tank again tomorrow to see if something in the line.

Ford Mechanic: jazzmaster, ASE Certified Tech replied 2 years ago
code 21 is for the coolant sensor system-try disconnecting that sensor and see if it runs better -if this is reading to low to the ecm it may cause it to run rich .
the 22 is the map sensor ,did you try to unplug the electrical and see if that made a difference ?
sometimes it may run better .
its always possible that a line got pinched ,
so let me know please ,,thank you ..

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.
