    Okay So What Is The Best Exhaust For No Drone Inside Car

    It doesn't matter if you have a $20,000 home theater system to listen to YouTube videos or not. All music formats and video formats that were designed for use on the internet use some form of compression to keep the size of the files to manageable sizes. This distorts and compromises the...

    Okay So What Is The Best Exhaust For No Drone Inside Car

    You are correct - different strokes for different folks. For the record I am a Ford Technician and have worked on all Ford/Lincoln/Mercury vehicles including Mustangs for over 20 years. So I don't base my opinion on YouTube videos. My personal preference for what I would like a street car to...

    Okay So What Is The Best Exhaust For No Drone Inside Car

    OK, being as I work on these cars for a living I have seen the gamut of aftermarket/modified exhaust systems out there. I am old school and believe a high performance engine makes all the music of it's own without the need of over amplification by ridiculously loud mufflers. The first 05 and...

    Misfire On All Cylinders?

    CKP = Crankshaft Position Sensor. I am surprised you didn't have a problem with the car stalling being that's what the problem was. That could definitely cause problems if the sensor output was erratic to the PCM. Good to hear it's fixed!

    Misfire On All Cylinders?

    Did you get the car back already or are they still working on it? Missfires can be caused by many things. They didn't tell you any other info? I would have to imagine it is still under warranty so I wouldn't worry about it unless the car still has the same concern after you get it back.

    Error Code P0153 And Rpm Issue

    That code specifically indicates a concern with the passenger side upstream oxygen sensor response being slow. There are a lot of reasons this code can set. Add into the fact your car has been modified and it can become more challenging to correctly diagnose the first time. If you "don't have...

    Engine Cut-out At Red Line

    That is not a completely accurate description of what takes place. Simply inducing a lean condition won't cause the engine speed to decrease. The PCM commands alternating fuel injectors to turn completely off when it senses a vehicle and/or engine over speed condition. It will continue to do...

    Engine Cut-out At Red Line

    It's called a rev-limiter and it's programmed into the cars computer to prevent damage from over revving the engine. Your car came with a standard 3 year, 36000 mile warranty from Ford. Don't really know what else you want to know as far as wanting "any ideas".

    Need Help Passing Smog Asap!

    Car is not going to pass without catalytic convertors installed. Simple as that. Even if you installed MIL eliminators and the check engine lamp is not on, there is a thing called a tampering inspection. Sorry about your/his luck.

    07 Shelby Running Lean, Help Please

    It's obvious the technician working on the car didn't know it had, and needed an aftermarket tune in it. Why they did it is anybody's guess. That in itself is the problem. IDS automatically attempts to identify the vehicle based on the VIN, not what calibration file is programmed into it...

    Off topic.. Looking for a good Fusion/Milan Hybrid site

    I'd do what Noobz suggested first. However if the cat. covertor heat shield is the cause, take it to the dealer if it has under 80K miles - it should be covered by 8/80 federal emissions warranty. If you can't find the rattle by banging on the exhaust some preferably with a rubber mallet...

    Problems With Idle

    When they replaced the alternator the battery was most likely disconnected which caused the cars computer to loose it's memory. The computer will learn idle strategy over time while you drive it along with other various parameters. Your car most likely has some mileage on it so it has...

    Off topic.. Looking for a good Fusion/Milan Hybrid site

    If you had any type of vacuum leak or unmetered intake air leak, or an exhaust leak upstream of the catalytic convertor a check engine lamp would set. Why exactly do you want to test it for an exhaust or vacuum leak? Do you have a check engine lamp on?

    Mil Eliminator Help

    I have seen this problem a lot when it comes to aftermarket convertors - they are junk. Instead of dumping more money on the problem, you should return to the shop that installed the convertors and have them install another set under their warranty. You may get lucky and get a good set. If...

    Whats Best Oil To Run,whats Ya Opinion

    Amsoil did not invent synthetic oil. Synthetic oil was developed in different formulations by the US and Germany during W.W. II for use in aircraft decades before Amsoil even existed. Amsoil was however the first company to sell synthetic oil specifically for automotive use to the general...

    Is Anyone Running Aftermarket Coils??

    In my opinion there is no bigger waste of money as far as modifications go. You will not get any appreciable horsepower increase, and in my personal experience they are more likely to fail than the factory coils. Save your money for something else.

    CAI and Disconnect

    When doing any modification or repair that affects the air/fuel ratio the computer keep alive memory must be reset to ensure the new parameters are relearned properly. This means you will disconnect the battery and loose all your settings on your radio and what not. Using a memory keeper will...

    Boss intake question

    The boss intake itself is legal. However if you install it on your 2012 GT you will need an aftermarket tune to make the car run properly. The aftermarket tune might be a problem. Check with the supplier of the tune if it's California legal. If you contact FRPP they might be able to make a...
