    Help please! 3.4l 94 camaro problems

    Hello i have a 94 3.4l camaro the problems i am having are: high idle ( the car idles around 1400-2000k rpms) and in the mornings i have to start the car up two or three times before it will stay running. also my biggest problem is when i am driving and i put the gas pedal to the floor the car does not have any get up and go like there is no power just gradually increases in speed and the car shakes when accelerating. any ideas or suggestions would be great. the car has dual 80s series flowmasters , k&n filter and thats all i believe

    Check fuel injectors(clogged of shorting out)??
    Check fuel pressure at the fuel rail?

    Ok to check the fuel pressure, you will need to find your port on the fuel rail, its a shreder valve(same as a tire valve that you put air in). When you find that you need to find or borrow a fuel pressure guage, and see what the pressure is. It should be close to 43.5Psi when the cars ignition is on but not running. When the car is running this will drop about 10 psi. So when the cars running it should be a steady 33.5Psi or so. Drive it arround while watching the pressure on the guage, the fuel port should be in the back of the intake manifold.

    For the injectors the best way to really test them is to remove them and check the resistance, which should be about 11.2 ohms at room tempeture if i remember right. Also you can actually remove the fuel rail, and leave the injectors attatched and have some one try starting the car and then while there doing that you look at the injectors to see if they all pulsate and are not clogged.

    If fuel pressure is low change the fuel filter first since its cheep and its good matenence.

    I have a 3.1l camaro which is almost the same exact car you have, so this info should be ok. Someone will chime in if im wrong on this but these methods worked for me when i was having fueling problems, if thats the issue your having.

    Fuel problems would not cause the car to idle high but would cause a rough idle or no start . I would check for vacuum leaks first, check all vacuum hoses for cracks and loose fittings. You can also pull and read your spark plugs.

    A high idle screams "exhaust leak" to me. I would check that too.
    Gonna be quiet again for a little while, so show some patience. It will be worth the wait.
    ...I promise you

    For the acceleration loss, if the fuel pressure is low, i would check the fuel filter and see if its stock or has been replaced. I would try seafoaming it through the gas tank and intake as well. Any codes?

    I guess i should mention that it there is a STRONG gasoline smell all the time whenever the car is on driving and just idling, whenever i press or depress the accelerator i can here a high pitch whistle type noise like a high pitch hissing sound??? (vacuum leak maybe?) thanks for the help everyone greatly appreciated.

    Hissing sound and high idle and power loss = vacuum leak. Check all your vacuum lines. Best thing to do is get some dawn or some kind of detergent, mix with water in a spray bottle and spray all your vacuum lines, and where there is a leak you will see bubbles. Best of luck!
