    DIY gear installers, rear end guys... chime in.

    The reason for using FRPP gears is that they are machined as a match for the dimensions of the original gears. In most cases you will be able to simply install the FRPP gears using the shims that you remove from the old set up and it will have correct backlash and pattern. Do NOT ASSUME that...

    Clutch all the sudden more "grabby"???

    The clutch has probably been overheated. SOMETIMES, this will correct itself if the clutch is used normally without overheating due to slippage under power.

    Steering wheel shaking...

    Warped rotors will cause this problem only when braking. I would start by rotating the tires front to rear and see if it feels the same. If it changes, the problem is tires. Sometimes an RFV check will not necessarily cure the problem. If you have a tire that has excessive RFV, they cannot...

    clunking everytime i shift

    In all manual transmission cars there is a small amount of slack. With manual transmission and clutch practice you will not feel NORMAL slack. If you have anything beyond normal, you will not locate the problem on an internet forum. The only way to locate the problem is to safely raise the...

    Manual Tranny

    Automatics are for people who WANT automatics. I'm a manual transmission lover because I just love driving a stick shift car. Driving ANY automatic car is just no fun to me. If you want a stick, where there's a will, there's a way. Since the invention of the automobile there have been...

    Cars running hotter than usual

    Just because the reservoir is at the right level, you still very well could have a low coolant level. With the car DEAD COLD, remove the radiator cap, not the reservoir cap and see if the radiator is full. If not start the cold engine with the radiator cap off and fill up with your coolant...

    Air conditioning

    Yes, what you describe is "short cycling" which indicates that the system has a low charge. If it has a low charge, that means it has lost refrigerant. If it has lost refrigerant, that means that there is a leak. If you charge it, that refrigerant will leak out as well. Find and fix the...

    SES Light Question

    Whenever the light comes on, pull the codes. You are absolutely flying blind otherwise. Reverse the change that you made and see if the code comes back again after being read and reset.

    07 GT's now have less performance

    Due to the fact that the 3V Mod motor has it's torque peak at a very high (for a street engine) 4500 RPM or more, going from a 3.55 to a 3.31 could actually use MORE gas depending upon your driving style. This isn't the sixties any more. Then engines had torque peaks as low as 2500 RPM or...

    Gear ratio change

    Going to a lower gear (higher numerically) will likely INCREASE your top speed, not lower it. This is due to the torque multiplication allowing the engine to overcome the wind resistance and other factors that fight against faster speed. These cars have overdrive final ratios and high RPM...

    3 valve noisy car

    Of course it's noisy. It's not a Mercedes Benz, it's a V8 powered, blood and guts muscle car, at least as cars go today. Now if you have a vibration, that's a different issue. It should not have any vibrations. The vast majority of vibrations are tire related.

    stupid girly question but...

    I'm plenty old enough to remember the Police Intercepter designation, but I never heard it referred to as a PI. There were a very few engines that were ACTUALLY Police Intercepter engines, but most anyone who had four barrel V8 in their Ford would call it a Police Intercepter. I stand...

    checkin spark plugs with removing fuel rails?

    Sorry stangnet, I must not have read your post thoroughly enough. That said, although I HIGHLY recommend not touching plugs unless it has set overnight, I have changed a number of these with only 30 minutes cooling time with no trouble. It's not the most comfortable job you will ever do...

    stupid girly question but...

    One of your questions has still not been answered. An S281 is a supercharged engine, so whether or not the base engine is PI or not you are WAaay up on power compared to a normally aspirated (non super charged) engine of either type. As explained, this involve different and MATCHING cams...

    You might notice that in my statement I indicated that cooling overnight was best.

    Gasoline smell in car

    This is a potentially dangerous situation. Start looking for the fuel leak and correct it NOW. Check the fuel filler neck, fuel lines, fuel filter and look all around the fuel rails.

    Traction control button

    Yes, you will save on your tire budget, but if you drive aggressively all the time, make SURE that you check your brake pad thickness OFTEN. Brake pads are not all that expensive and they are quick and easy to replace, but if you let them go metal to metal, then you will wish you had the tire...
