    Check Engine Light On

    Look for something that can affect both sides of the engine causing it to run lean with those codes. Most likely it's related to the mods you've done if the codes weren't there previously. A vacuum leak, any source of air entering the engine that's not going through the MAF sensor, a bad MAF...

    2 Month And Couldn't Fix My Problem, Can Someone Help Please

    I am not familiar with any of the aftermarket scan tools out there including the SCT. I would have to imagine that the SCT scan tool will give you a definition of the available PID's somewhere - either through the tool itself in some manner or in a manual that came with it possibly. Maybe...

    2 Month And Couldn't Fix My Problem, Can Someone Help Please

    I am not sure what you basing the diagnosis of "no normal fuel delivery" off of, and you haven't mentioned specifically what PID's you were monitoring. What you want to do if you suspect a fuel delivery problem is install a mechanical fuel pressure gauge and compare it's reading to the FRP...

    2 Month And Couldn't Fix My Problem, Can Someone Help Please

    I watched that video and can't make any determination from it at all. Was the check engine lamp on? Do you have any codes? What specifically makes you think that there is something wrong with the car? Checking voltage at the fuel pump on a vehicle with this type of fuel system is not an...

    Interesting Message From Mobil 1 About 5w50

    They were trying to tell you their product is good, but not good enough without sounding like saying their product sucks. Ford does have higher standards in certain instances believe it or not. If Mobil 1 told you that their oil did meet Ford's specifications then they would be opening...

    Spark Plug Removal Hot Or Cold?

    That's awesome! The damned things shouldn't break no matter what you do, especially when removing them by hand! I've replaced thousands of these plugs and in my opinion it makes no difference if the engine is cold or hot. The only real thing that seems to make a difference is mileage. The...

    Russian Roulette......

    Yet another reason to not use penetrating oil, but carb cleaner instead per my 2nd recommendation in post #7 above.

    Russian Roulette......

    Cool, let someone else take the hit on depreciation, and you get a practically new car - gotta love it! In my experience antiseize doesn't really help. It's not going to hurt though, so if it makes you sleep better - go for it! The problem isn't with rusted/seized threads, but with varnish...

    Russian Roulette......

    7000 miles on a 06? Damn, if you aren't gonna drive it, why'd you buy it? The lower the mileage, the less likely you are going to have a problem. I wouldn't think you'd have a problem, but never say never!

    Russian Roulette......

    You will no doubt get differing opinions on this, however as someone who has performed on average 5-20 tune ups a week on 4.6/5.4 3-valve engines for many years now, I will post my opinion. 1st, plan on breaking at least one plug. You might get lucky, but you might not. If you aren't...

    Why Did Ford Not Use The Tr6060

    Noobz is pretty much telling it like it is folks. The dealership I work at has had EXACTLY one of these cars in that needed an actual repair done to it beyond updating the trans fluid. This car had plenty of mods done to it, so it's a safe bet it wasn't driven easy. By and far the biggest...

    Misfire On All Cylinders?

    I agree with everything that you have stated. It is definitely unusual and it's possible something entirely different was wrong with the car. It's impossible to know for sure, but what the dealer told the OP is not impossible. If the OP is reading this, I wouldn't worry about any of this as long...

    Tune

    I have no idea what GM does, they might be different, they might not. If however you took your Lightning in for a warranty repair with an engine knock, trans or clutch slips, major rear end failure, any aftermarket performance mods including a tune would be inspected for and taken into...

    Tune

    That sounds like a crock to me. The only reason a dealer would ever do something like that without telling the customer before hand is if the car had a recall on it in which the recall involved reprogramming the PCM. There are no recalls of any such kind on Mustangs. If the car is under...

    Tune

    If you take your car in for something like an oil change, or maintenance, they are not going to check for a tune. If you however take it into the dealer for a concern that would ordinarily be covered by warranty and you have some type of drivetrain failure they will almost certainly check it...

    Misfire On All Cylinders?

    I agree with that. In theory you are correct. In actuality - not necessarily. I have seen more than a few vehicle's with crank sensors that didn't work and they had no codes in them at all. As far as missfire codes, it depends on how frequent the missfire has occurred as to whether a code...

    Misfire On All Cylinders?

    The OP stated right in his last post the connector "wasn't fully seated". I have seen this many times on various connectors of all types on vehicles with low mileage. It's not a matter of them becoming unlatched, it's that they never were fully latched to begin with. The concern was a little...

    Exhaust Bbk Long Tube Headers And Catted Shorty X-pipe Tuning Problem

    Welcome to the world of aftermarket parts. Sorry, had to say that The problem is with the aftermarket catalytic convertors you have. Plain and simple. A different tune may keep your check engine lamp from coming on and setting catalyst efficiency codes, but after that has been done the car...
