i have a 96 monte carlo z34. when i drive down the road the rpms flutter 100 to 200 rpms. its not very noticably feeling wise but i can notice it just because i look at my gage. it will also start really shitty sometimes if i shut it off and start it up within a small amount of time and when i push on the gas it acts like it doesnt want to go and makes a terrible noise after a couple minutes it evens out and drives fine. thats only if i start it after a short amount of time of it being turned off. its fine if sits for a while. i changed my fuell filter and it ran good for two days and started acting up again.

I own a shop, and have worked on many vehicles. What I would think is; IF it ran fine AFTER you changed the fuel filter, then is this not a clue? You may have trash in the fuel tank, as this would explain it running fine, and then going bad again after a few days. If you changed the filter, and it solved the problem, then the fuel delivery system is at fault. Change the filter again, and if it resolves the problem again, then you have a bad fuel tank. They can go bad, and the coating inside the tank will flake off plugging up the filter. Someone putting trash or sugar into the tank can do this, but something is stopping up the filter. A real weak fuel pump may be the culprit. I would remove the tank, and have a good look at the condition of the inside of the tank. If it looks good, then have the tank boiled out at a radiator shop, replace the pump, and replace the filter. When you have the lines off use compressed air to blow them out to make sure the return line isn't stopped up too.
Glad to help out, good Luck!!!

You might want to call around to the auto parts stores and see if they have a machine to check the computer on your car. They usually can tell you what is wrong with it without going to a machanic...
my daughters mitzubishi eclipse did something like that and it was the computer. This car would start then stutter and then sometimes die and sometimes it would go. Once we got it going it would miss and sputter, for sure if you stopped at a stop sign it would act up. Then it decided it didn't want to go anymore. we got another computer at a import car junk yard. for cheap.. we did get the part at a parts store but it didn't work and was much more expensive...
My trailblazer did something like that and it was the fan clutch. The trailblazer no matter how long I waited to warm it up when I took off it didn't want to go anywhere then it would sound like a 18 wheeler taking off... after i'd get going it would stop and act fine most of the time.
could be bad spark plugs, wires, and/or rotor also..

When my daughter's Suzuki ran rough it turned out to be air leaking into the fuel system around the gas cap. We replaced the gas cap and it ran fine. Other than that it sounds like a sensor problem.
