hi new to forum, i have 97 ford f-150 xl 2wd. i put truck on tester and a code saying dtr or something showed up mechanic said it was my computer and i have 3 cylenders misfiring. my inspection is due next month can someone give me more details on this dtr code i may be wrong with exact letters of code but he said its my computer cause check engine light is on thanks.

 

I think there should be a code number. Do you know what it was?

 

Take it to an autozone or napa, o'rielly etc. they can pull the DTC (diagnostic trouble code) for you. When you get the code, re-post it on here for more help.

 

thanks i will check again it was at an autozone but will ask again cant change plugs myself they seem to be a bit rusted in place so it needs to go to shop anyways no money to buy another truck right now so seems like i will be dumping some money into this one again thanks

 

ok got numbers 4,5,6 cylenders misfire and codes 1537,1538 witch is intake runner control stuck open auto parts store wants 150.00 apiece but told me to do a gasket set first and see if it will go away. not counting coil pack what is worst case senario about this motor job thanks in advance.

 

Bump.

 

Doing intake gaskets wont fix the IMRC codes. As far as the misfire codes sounds like you have a V6 so try replaceing the plugs and wires first then, move to the coil pack itself.

 

ok thanks i think im going to try and get another truck plugs are stuck and i tried putting in the number 6 plug but dont go in all the way plus number 6 needs to be rethreaded as my old plug kept coming loose.
