    Forced Induction Hi Flow Fuel Pump W/o Supercharger

    It should be okay. The PCM should automatically throttle back the pump by reducing its PWM duty cycle to achieve the correct fuel rail pressure.

    2000 Gt Engine Noise!

    Sounds a little "light" to be a rod bearing. Perhaps a timing chain tensioner problem? Either way, you're going into the engine.

    Cats Or No Cats

    700HP Hellcats are running through catalytic converters. I don't believe a lightly-built 4.6 should threaten a catalytic converter unless they're dumping so much fuel the cats overheat, go cherry red and blow their guts. Get the tune right and they should be fine.

    Car Vibrates And Shakes

    It's possible. You have a convertible...a New Edge convertible. Not exactly bastions of rigidity at the best of times, probably flopping around without that support. If you're talking about this: then yes, put it back on and get back to us.

    When you had the flywheel resurfaced did you/the shop reinstall the dowel pins?

    Engine Won't Accelerate After Several Miles Driven

    V6 is a 3.8, no? Anyway, it sounds like it might be starving for fuel. Perhaps your tank venting is insufficient. If it's very repeatably doing this, you might trying removing the gas cap (open the tank to the atmosphere through the filler neck) and trying to drive it again to see if it improves.

    Questions About Supercharger On Pi Swapped Motor

    You're at about 10.5:1. If you intercool it, keep it to about 8-9-psi, run a conservative tune and use premium fuel you'll probably be okay. Fast, cheap, reliable: Choose any two :)

    No Oil Pressure After Rebuild? Help!

    I've heard of oil pump gears shattering on high RPM cars with incorrect crank dampers but that's clearly not the case here. I think the oil pump is coming out of yours for a look see. A few thoughts come to mind: - check the oil pressure relief valve & spring are properly installed and not...

    Did you check with Crutchfield? They probably have a plug & play adapter kit for what you're trying to do.

    P0302 Code Has Me Puzzled

    Compression test would be my suggestion. Rather than focusing on a specific number, I'd get the numbers for all cylinders and look for anomalies (e.g. #2 10% below what the others are showing.) Really weird that #2 had a janky coil and injector on it...

    4.6 Mods

    Gears will make the car feel faster though it won't actually be. Cams can give a decent gain up top on PI-headed engines but the gains are coming at the top of the rev register. My personal opinion is that most bolt-ons are not worth it; the cylinder heads, small bores and generally tiny...

    Rocker Arm Fell Off And Spring Is Compressed

    The valve head could be bent, the stem is seized in the guide or perhaps the spring itself is broken. Something (a piece of the piston which may happen under severe detonation) could be wedged between the valve and the seat preventing it from closing. What did the spark plug look like? Any...

    Brakes Low Brake Pedal After Service - Need Advice

    The pedal sinking to the floor when at a stoplight ("If I'm stopped at a light or something, and I apply moderate pressure to the brake pedal, it still travels almost all the way to the floor.") suggests a problem in the master cylinder, especially if releasing the brake pedal restores pedal...

    Help With Noise While Turning

    A few thoughts: - oil level in the diff correct? - oil type (with friction modifier added separately as necessary) correct? If you only hear this on left turns from the left side you might consider looking at the thing more closely: - lift the rear and remove the wheel - remove the left rear...

    Misfire

    You won't be able to erase the P1000 and it's not related to your misfire. You probably reconnected the battery recently and haven't driven the car enough under the right condition for the PCM to perform all of its internal "monitor readiness" tests (emissions stuff like evap, O2 sensors and the...

    99 Mustang Gt Won't Idle

    If you touched any of the intake ducting, the airbox, MAF sensor etc during the rad change check to make sure you plugged everything back in correctly and tightened all clamps. It almost sounds like you have a sizeable vacuum leak ahead of the throttlebody.
