1997 Ford Ranger, 4 cylinder, about 200K miles, recently replaced fuel pump & timing belt, files fine, no acceleration-boggs off when trying to accelerate. Now in a repair shop for over a month and they have tried many things with no luck. HELP!!!
1997 was a cusp year for Ford - some vehicles still had carburetors, most had Fuel injection. If carbed, you probably have a faulty accelerator pump diaphragm in the carb. If fuel injected, it may be the throttle position sensor or m.a.f./m.a.p. sensor. If the shop does not have the proper diagnostic equipment, you could throw a lot of money away on sensors and labor and still have the problem. The onboard computer will have codes stored in it which can tell you what is wrong. If no codes, then the computer itself could be faulty and the diagnostic equipment will detect that too. It could be something simple like a dirty maf/map sensor which could be cleaned in about a half hour. Find out if the shop has the right diagnostic equipment less than 10 years old . If they hit you with an arrogant or off putting attitude, have it towed to a properly equipped, A.S.E. certified shop.
Hope this helps and thanks for using Fixya!
Thanks for the info George. I will definitely check with them. It is fuel injected.

probely a fuel filter or you would just need a tune up like spark pluges and wires

vacuum advance working ? do manuel check with cap and rotor button off and see if it's moving. chris
SOURCE: Engine boggs down
either fuel filter or fuel pump...replace filter since its cheaper. 6-12 dollars at autozone

havent a clue here ,one cylinder now another missing ,only one thing comes to mind here and thats the coil pack ,check the voltage across the battery with engine running at 1500rpm and if its higher than 15.5 volts of their abouts then the alternator regulator is playing up and this would cause problems with the coil pack or the ECU ,also the radio could blow and lots of bulbs.Other that this i would need to get my greasy hands on it and give the magic hammer treatment
