1993 Ford F350 code 327


have you removed the egr and checked for plugged in the egr port or damage to the egr itself... i think it's more of a flow issue associated with the position of the egr and not the solenoid itself... koeo/koer tests are a pain even with a break out box... good luck as this year (early 90's) of Ford's are the worst for diagnosing computer/running issues

I have a 1991 F-150. Runs great but wants to shutoof at stop signs and when you out it in gear sometimes. Any suggestions on the problem? Maybe the TPS?


the first check you should do to solve this issue is a KOER and KOEO. More commonly known as "pulling codes". I have linked the instructions on how to "pull codes". In a nut-shell you need to use a length of wire or paperclip to "ground" a pin on your self test connector (under the hood, driver side). Then, you get in the truck and turn on the key and count the blinks of the check engine light (CEL). This is called a KOEO (key on, engine off) test. For the KOER (key on, engine running) you will need to warm the vehicle to operating temperature then go through series of "press the brake, turn the wheel, press the OD switch etc..." and it will test all of your sensors. Then, it will blink some codes at you once this process is complete. It might be annoying at first, until you get the steps memorized. However, once you've figured out how it works--it'll be a life-saver. Don't replace a component without out doing a KOEO or KOER, first; or your just wasting money. Hope this helps

sounds like you definitely need a new throttle position sensor. code 53 is saying that TPS voltage is too high. after you replace that, i would disconnect the battery, get it up to operating temperature and run another KOEO and KOER

My 450 ford moter home turns over but will not start I suspect feul pump


Hello mfsbrown: My name is Roger and I will help. First thing to check is to make sure the fuel filter dirty. Next you should check the fuel pressure. This will require a fuel pressure tester. You did not say if you have a gas or diesel engine. So I will furnish both test pressures. For a V-10 gas engine. (KOEO) Key On Engine Off 35 to 45 psi. (KOER) Key on engine running 28-45 ps. IF your engine is a diesel then the pressures are (koeo) 30 psi. min. (koer) 30-80 psi. If the fuel pump is your problem. Make sure to replace the fuel filter. A dirty fuel filter will cause damage to the fuel pump. Should you need further help please just ask. Please rate the answer. This way I know it was helpful. Thank You for using Fix Ya. Roger
