I would check to make sure that the Oxygen sensor is hooked up or is actually able to work with Headers.  I have heard, not experienced that you might have to get another o2 sensor.  Hope this helps.

Whoa, Marty. Slow down. I gotta fix the flux-capacitor first.

you might just need a tune-up, or it could be more serious, try changing the spark plugs, distributer cap and rotor, a fuel additive wouldn't hurt either

just turn the handle, dont over do it too much though. go in fast, let up on the speed and turn hard then gas it again

give it a good cleaning, especially in the gas piston area and other parts associated with cycling.  use a good oil like Remoil, CLP or Triflow.  stay away from WD-40.  also, try a higher dram shell.  those cheap promo loads don't have alot of powder, and they burn dirty.

if you don't know what you're doing. go to a local auto parts store and check out the repair manual for it.  it should give you a procedure for replacing it. if it seems like too much, then just get it in the shop.  don't put this off either, becuase if you do, it'll overheat and then you're out an engine.

have to know what kind of engine you have in it? Aparently it's sucking air around the primer pump, the filter or in a fuel-line or somewhere else. Just depending on the engine type...Also maybe the filter isn't tight enough..It's getting air before the pump....may need to bleed the injectors to get the air out..

I believe your problem is in the setting of the ignition timing, not the fuel injection.  Reset the timing according to specifications, and your reverse run will disappear.

Download this: http://www.drivercleaner.net/ and follow the instructions explicitly.  It will cure your problem.

Possible that it is the cat. Save dollars and punch it out b4 replacing it.\nTiming may be out. Check this first. And not just at one mechanic.\nDid you replace the fuel filter(s)? Air filter?\nJust for an experiment, get some carb cleaner and while the engine s running, spray it around the intake manifold, base of the carb, any hoses you may see. If the engine starts to die or rev up, then you have a vacuum leak.\n\nGood luck.

I believe you just have to take slack out of governer spring.I think on those as you pull the throttle it has a certain tension then the sping just streches. Elimenate the spring strech with a plastic tie strap.\nBill

buy a manual boost controller and boost gauge used on ebay, and crank that baby up, not too high tho or it will hurt the motor.  im not sure exactly what type of turbos are on a stock 3000gt, but i had my stock tsi turbo up to about 17 psi or so.

yeah this is kkkkeeentt  umm u should just get a stock exhaust and that will go twice as fast!

Scrap both ideas and get a cam, port the heads, and carburate it.  You'll see more results than fuel injection for a very reasonable price, a pre GenIII small block like yours is cheap to build up!

First, know what your talking about. How can you have "turbo" headers if your running on motor? Turbo headers is known as a turbo manifold, which sends the ehaust to the turbine. \n\nAre you looking to go all motor or boost?

Try adding a can of Chevron Techron to the fuel tank next time you fill up. This will clean the fuel injectors and is the best product of this type on the market.\n\nYou might also have you mechanic check the fuel system framazoid. This part often fails in cars more than 10 years old.\n\nGood Luck!

First - the word is "exHaust", not "exuast".  Losing the caps would be nice, too ;-)\n\nanyway..\n\nOnly a less restrictive exhaust -system- will change the sound noticeably.  Around here, those mufflers aren't known as "fart cans"; they're known as "cop callers".\n\nNoise for the sake of noise is useless.  If you want growl with a purpose, get a Mustang. Affordable, easy to get parts, and you actually get some performance for your buck.
