When driving my car I can't accelerate normal , I have to ease into it very gentley or the falls on its face. I'm guessing it's starving for fuel. Would this be caused by bad injectors or bad fuel filter or is it somthing else maybe?

A good bet may be that your filter screen in the tank may be getting clogged, or the fuel line is collapsing. Does the pump "moan" when you try to accelerate?
There are lots of possible causes - but this is fairly common.
Also, park the car - start the engine and open the engine cover. Rotate the throttle spool by hand and see if the exhaust smells of unburned gas. Make sure the Catalytic converter is not glowing red (easier seen at night with the lights off temporarily). Does youe exhaust system hiss? Does the car idle poorly? Have you had any work done recently?

I had the exact same problem several years ago after my car sat for 10+ years.
It was injectors.
I could ease my way up to highway speeds if I did it gradually but if I tried to floor it or even accelerate quickly, it would just start this powerless gurgling. I fought with those injectors for a year, cleaning them regularly with a sonic cleaner but in the end I just replaced the injectors. Never had a single problem afterward.

Using sonic to clean injectors that open on pressure will never reach the goal.
This type of injectors can only thoroughly be cleaned in a system that uses pressure to open the injectors.
Besides that, longtime unused injectors get bad spots on the seats, due to rust.
If that has happened, replacement of the injectors is the only cure.

Hey Mike,
Your car is a stick shift, right? The VIN registry indicates this, but was just double checking. I'd say the guys above with experience with injector problems are probably right. Before I saw their messages I had thought it could have related to a failed auto trans shift computer governor. They fail in bizarre ways so this might have been one of them. If you have a manual car then of course this wouldn't affect you.

Does it only do this cold or all the time?
Has it always done this (as long as you've had it) or did it just come on suddenly?
There are may things that can cause this, with more info we can narrow it down faster instead of throwing lots of expensive parts at it to test it.
