SUBJECT: # 13587: F150 info

Submitted by Tomcat ( from KENTUCKY on 4/12/2012 10:24:00 AM

Guys. Need some help. 1999 F150 Lariat, 5.4, 4x4, 125K miles. Can't tow the boat till it's fixed! Idles fine, but when gas pedal is pushed moderately, it starts bogging down, jerking, etc. If gas pedal is feathered to get up to cruising speed and level off, cruises fine. If gas pedal is mashed, it will do fine. The MAF sensor, 2 upstream 02's, and fuel filter replaced about 2 months ago. Started doing this just after gassing up last week. Check engine light had been on for some time, but wouldn't stay off after fixing the codes. Had it hooked up again yesterday, and it showed codes for what had been replaced. Had it turned off yesterday, and it's still off, but is acting up as described. Short of putting on diagnostic machine, any ideas? Bad sensor(s), plug, wire, coil, tps, tranny? It is time for plugs, however. Sorry for long post, and thanks in advance.

    I do not want to sound like a dick but IMHO more money is wasted on parts swapping trying to fix problems in vehicles than it would cost to have the real problem diagnosed by a competent mechanic.

    Anyone can swap parts but replacing a good part doesn't fix your problem and if you're buying parts at some of these discount auto parts places the parts you're putting in are at best junk.

    You have to have the correct equipment to determine what's bad and you have to have the training to know what you're seeing on the machines.

    I would highly recommend you take your truck to a good mechanic. You cannot save money but guessing what's wrong and buying cheap parts.

    well you do sound like a dick

    I took my Merc to a local mechanic and he cost me 350.00. After another lost day on the water I took the boat four hours to my normal mechanic who correctly diagnosed the problem (a bad wiring harness due to the missed problem earlier) and fixed my motor. It took several hours to chase down exactly what was wrong with that engine.

    If you don't like the truth you can select the ignore option on my reply.

    Never said I was doing hit & miss on parts. Just wanting opinions so I can get on same page with mechanic. Thanks anyway.

    It's not uncommon for a lot of "repair" places and "mechanics" to do exactly what I said was an issue. Anyone can change a part, it takes a trained automotive technician with the right equipment to KNOW what part is bad and how to replace it correctly. And IMHO a lot of these discount auto places sell crap parts.

    I'm sorry if it sounded like I was blaming you.

    Also there is no way with the information provided to do more than guess.

    Next time this question comes up I will keep my opinion to myself.

  7. 4/23/2012 11:12:00 PM Submitted by Tomcat #11840 from KY says It's also......
    It's also not uncommon for a "reputable" repair shop to do what you suggested. I AM taking it to a "reputable" shop with diagnostics, just wanted what I thought were some good "opinions" here so I don't seem stupid when discussing the results with them. My bad. Opinions have no value if kept to yourself. And they're just that. Take what you want, and leave the rest.

  8. 4/24/2012 9:11:00 AM Submitted by MikeF from FL says same answer
    It needs to be hooked up to the program Ford mechanics use not a code reader. The laptop will tell you what the bad readings are not what code the truck computer kicks out. Using a code reader will fix the problem 95% of the time; I'm guessing you not in that group.

    My brother is a Ford mechanic and has been for over 20 years. He now owns his own shop and still works on the vehicles that need diagnostic work. I could call him right now and he would tell you exactly what I just did. You need to see the actual data and understand where it comes from.

    The guy that wrote the custom program for my Ford would also tell you the same thing. When he writes the programs he has to see the raw data to get the most power out of the engine. We had this exact conversation 2 months ago.

    Maybe my answer sounded sarcastic and condescending but it was correct. My sarcasm comes from reading the exact same questions on the board a thousand times over the past 17 years and having people argue with the truth.

    And I totally agree about bad mechanics in good garages but if it's a well run garage the owners/managers now when to jump in and lead the tech down the right path. In the nicest way possible; you really should take your truck somewhere else.

    I have been in the service industry for 40 years I own a service company and have just over 100 employees. I do understand what it takes to fix stuff (we do not work on cars but we do a ton of work for people who build cars and parts for cars). You cannot fix anything until you know what parts are bad.

    Understand. I AM taking it to the Ford dealership where truck was purchased to have diagnostics done. (very soon)Like I said before, before the diagnostics appt., I was just wanting some opinions on what it might be(hopefully from someone like you)to educate me so when I hear the results, I have some idea what they're talking about and don't get snowed too much. Early on, my friend's code reader showed the 02's & MAF sensor, which he could get the parts easy & cheap enough & replaced. Didn't work, and called & made appt. for Ford diagnostics. In meantime, just asking for valued opinions on this board, not a lecture. Guess I was wrong. Guess I'll keep the results to myself.

  10. 4/29/2012 8:19:00 PM Submitted by MikeF from FL says wasn't a lecture
    It was an attempt to let you know what I would do to solve the problem and even why. Anything else would be just someone's guess.

    sounds like plugs to me . have you ever changed them .some 5.4fords have to have a special tool because the plug breaks off . i think that is on the 3 valve engines .
