    Exhaust Back Pressure

    I guarantee your loss is not in the exhaust. It is in the tune. I have my exhaust ( V8 ) opened up at the cat outlets to 2 1/2" (stock is 2 1/4"). Into a single 3" tube and a Magnaflow 3" muffler and 3" out the back. The area from the stock exhaust is up by 24% out of the cats and 20% in the...

    Power Steering Pump

    I flush my power steering when I flush and service my transmission. Every 50K miles. I have also learned to use Mercon V trans fluid in it rather than basic Mercon III. It has a fairly high amount of friction modifier in it and really helps to quite down the pump and even runs much smoother...

    Door Panels/Rear Child Locks

    I can help on the panel removal, but I have not played with the child locking mechanism. I would say from experience that the child lock is a simple mechanical mechanism that removes the ability of the cable from the inside release to become disengaged at out handle right above the switch on...

    Engine makes whirling noise

    It is most likely your cooling fan. It is either going bad and locking up or you have the air conditioning/climate control on and it is locked up to pull more cool air across the A/C condensor

    2008-10 ST On with Ignition Fuse in Internal Panel

    You should be able to use the small red wire feeding through the fuel safety shut off switch. It is full power when key is on. Use it to trigger a relay only. Then run your feed power to the camera through the relay...

    De-tuning my '10 STA a little

    On my K/N it seems to have more of a harmonic tone than just the big rush of air at say medium to lighter throttle positions. It doesn't bother me much really. But, if does bother you, you could use the spray can style of tool dip ( plasti-dip or Rustolium flex-dip) and spray the exterior of...

    Pulstar Pulse Plugs

    On my 4.0l's I have come to what I believe is the best combo, a replacement platinum Motorcraft ( stock heat range) plug gapped @ .060" and a Screamin Demon coil. I always use a plug wire that is a spiral wound core not a carbon suppression core. That is about the best you can do for...

    high rpm in neutral

    Have looked into a vacuum leak? It probably doesn't have one buy the way you explain things are happening. But, I have seen a lot weirder stuff before. I suggest checking for one as soon as possible...

    Muffler ?

    The exhaust is built out of 409 stainless. It is ferritic, hence it has a fairly high amount of carbon in it. It will rust and a magnet will stick to it. Once it rust to a degree the corrosion will seal it from corroding any farther. Kind of like anodizing of aluminum. The exhaust is...

    Looking to lower

    Yes, I have and can build more. But due to increased cost of products the price is higher at $1,400.00. It will ride similar to stock, but firm and taught, yet handle far better too. It will be adjustable from about 1" to 2" of drop. It will have new dampers, springs, spring seats, adapters...

    Mass Air Flow Sensor or O2 Sensors Needed?

    Oh Jeeez, an analog voltmeter will not and can not short out an ECU. Particularly in an ohm measurement mode. The TPS is a simple pentiometer. Hence, voltage in ( 5 volts ), a reference wire usually right below or at 1 volt @ idle ( key on engine off ). And a ground wire. Once probed to...

    Mass Air Flow Sensor or O2 Sensors Needed?

    It is most likely not your O2 sensors. They are what is sending the code. It may be the MAF... The vehicle has a lot of miles on it too. My experience says to check the TPS. It could be going bad and giving too high of voltage reference. Check it with an analogy volt meter. Using the ohm...

    2007 Limited 4.6 (Surging or Pulsing?)

    How many miles on vehicle? How many miles since transmission service? It sounds like the clutch in the torque converter is unlocking and locking. It is probably in sixth gear by then and feels like it is have a hard time with torque output and rpm level. My truck usually doesn't go into...

    Saleen Wheels

    I have 20 x 9 wheels with a 25mm offset. A 10mm increase in offset will most likely give you a rubbing problem on the inside with an 18" wheel. I believe the wheels designed for an SN95 Mustang like in the picture will fit best. They are usually 18 x 9 with a 24 or 25mm offset.

    Gen 2 V8 waterpump replacement?

    I myself prefer to use either a Napa premium brand pump or an OEM factory unit. As for the electric conversion I used a fan from a 05"+ Mustang GT. I bought a new one for about $125 from Rock Auto online. It is a Motorcraft new replacement unit. I am surprised at how quiet it is... I...

    Gen 2 V8 waterpump replacement?

    I haven't replaced the water pump but, I have installed underdrive pullies and an electric fan. You will have to remove the top section of the fan shroud, P/S reservoir moved and overflow/degas bottle removed. The fan will have to be taken off. Use a 36mm fan wrench. You can rent one from an...

    Magnaflow muffler Performance 11225

    In my opinion that is the wrong muffler. If I remember right our exhaust diameter is right at 2 3/4". You would be better having an exhaust shop expanding the exhaust into and out of the muffler rather than crimping/swedging it down and restricting flow more. Also the case size you picked...

    power steering fluid dark and poor performance

    Flushing can be done by most vehicle owners. The return hose can be disconnected and run into a jug of some sort. Your system probably needs a good cleaning and has a sticky valve in it. Is the pump groaning or loud when turning? Drain about a quart of fluid (from the power steering system)...

    Need Help

    IT is most likely a toe out situation. How ever the front end should be inspected while being aligned. It could be a bad ball joint or tie rod end causing toe out while rolling forward. If not caught the alignment is pretty useless...

    Egg smell, hesitation

    I have had this problem before. It is not a bad catalytic converter, at least probably not yet. It could be a bad O2 sensor causing a rich condition. But, it is most likely a bad TPS or coolant temp sensor. Also make sure to clean your mass air meter....
