I have an 2.8 85 firebird.When i hit the gas it waits for about two seconds and then goes.Whats the problem?Also,my gas pedal is really stiff and hard to push.Is this normal on old cars or what?
Thanks

Hope you have $2000 on hand cause it sounds like you need a new tranny..... Or maybe not. Does your car rev up before going? If it does, then you need a new tranny. That's what happened to our '87 Bonneville. If it doesn't rev, i'm guessing there's something wrong with the fuel line or the way its connected to the gas pedal. Has the pedal always been stiff?

Ive only had the car about 8 months but it has been stiff ever since ive had it.Anymore suggestions?

Sweet,

Check the accellerator cable. Disconnect it from the throttle body and make sure it moves freely. With the cable disconnected, try moving the throttle valve by hand to check for binding and stiffness.

If the transmission is slipping as Most suggests, you should hear the engine speed increase without the car moving. If this is the case, check the fluid level in the trans and pray.

If the engine itself is hesitating, the transmission is probably not the cause. Incidentally, the fuel line isn't really connected to the accellerator, unless you consider that both the accellerator and line are connected to the engine at some point.

It's likely that the fuel mix is going lean on accelleration, which isn't really that uncommon on port fuel injection systems. You should start by cleaning the Idle Air Control and Throttle Body. If you have a digital voltmeter, you should check/set the Throttle Position Sensor output in the idle position. As long as you're doing that, you might as well adjust the throttle minimum air position to the 400RPM factory specification in DRIVE.

You also need to confirm that the fuel filter is clean, the in-tank pump is producing the correct pressure of 37PSIG +/- # PSIG, and the ignition timing is correct.

If the fuel and ignition systems are in good order, the problem should be minimized.

Screw it, use this as your excuse to put in a 350

-80 Camaro 350, Carter AFB, headers, dual exh, ram air, all sorts of crap
-88 Iroc-Z 350tpi, 3.27 gears, 4 wheel disc, MSD 6a, tpi airfoil, k+n's, white gauges, accel coil, flowmaster, pretty quick

 

hmm thats a tuff one, you V6 thirdgen dosn't go when you hit the gas. it could be that you dont have a V8.

Gold85, if you can't help, then...

Sweet_85, are you comparing the gas pedal to a different car? F-bodies usually require more push than, say, a Pontiac GrandAm, or Buick LeSabre. If you're not and you really have to land down on the gas pedal, the bushing that the throttle linkage rotates in could be shot. That happened to my dad's FWD 2.8l car; the bushing wore out so the linkage was trying to work at an angle. You could tell just by working the throttle body linkage directly (as Vader mentioned!) that something was wrong. Our mechanic pressed in a new bushing for $5, but a few months later the problem returned. A $25 junkyard throttle body fixed the problem.

([edit] Remember: If you get a junkyard throttle body, you need to set it up for your engine! Make sure to re-adjust the junkyard TB's minimum idle stop, reset the IAC motor, and readjust the TPS sensor for -your- motor! The directions are on this website under the tech section. In fact Vader just posted them in this message: https://www.thirdgen.org/messgboard/...ML/004412.html Your throttle body looks different than the V8 one, but the exact same procedure applies.)

I also bet you're overdue for a major tuneup. Go to the V6 board, and click on search, and type in "Major Tuneup". My message should come up- it lists everything and anything that should be replaced for a major tuneup. Plugs & wires doesn't make for a major tuneup. If that message isn't under the v6 area let me know, I'll go there (sigh) and re-post it.
