    Should have mentioned that the leakis in the quick connect fitting - is there a way to change just the fitting??

  • rworkman112 Sep 09, 2009

    Apparently a mouse has chewed a hole in the Quick connect fitting on the fuel pressure regulator end of the return line - is there a way to change the fitting only -

Overreving with no power and excessive gas consumption air filter cleaned map sensor replaced fuel pump and filter


usually caused by busted diaphram in fuel pressure regulator allowing fuel to be drawn thru regulator directly to intake manifold. Pull vacuum line off regulator, plug line with golf tee, start car and watch to see if gas comes out of regulator. If yes, turn off car, replace regulator. The regulator sits near the fuel rail on the top of the engine as shown below. I will paste replacement instructions below from autozone.com in case you need to replace the regulator. Please let me know if you have any questions.

2005 chevy impala power steering have leak but can't find it.


Common leak points are the p/s lines, specifically the pressure line where the hard line and rubber hose are crimped together. Also check the pump itself, steering rack and fittings, return line and cooler (usually just a loop in the return line). I usually like to clean off the area where i find the leak with some brake clean and drive the car for a bit. It's easier to find the source of the leak when the fluid isn't all over the place.

I replaced the coil blocks, wires, and plugs on my 2005 chevy impala 3.4. I am still getting random misfireing, what else can it be?


could be a fuel problem or a fuel injector. these engines are also bad to leak water at the intake manifold gaskets, if coolant leaks internally it would kill the spark and cause a misfire. if its not low on coolant though i'd keep checking fuel and fire

could be the injector washers leaking or leak off pipes but you will have to remove the rocker cover trim for inspection
