Have you checked your air filter to see if it is bloked slightly, or if you have a CAI check it is clean.

Check your basics

Plugs, Plug Wires, Air Filter/CAI. When was your last oil change? Fuel filter? How many miles on your car? Tell us more!!!

i have bosch platinum +4 plugs, kore ignition wires, about 46000 miles. i do need to change the oil and the fuel filter. but the air filter is fine. i was going to put a little fuel injector cleaner, but i don't know what else to do

I also have 46000 miles and I think my fuel filter is clogged than a muthfukka. I keep getting beat off the line at stop lights. my car hesitates when I stomp on it. I just changed my plugs today. and it madee a slight improvment in acceleration but it still drives like poo

If you have a multimeter, check your injectors. If not, try a can of HEET or similar, that may help you out. Also jus ttry resetting your ECM. Your fuel maps might be fucked up somehow.

Check if any of the brakes are binding if this came on suddenly bro, and good luck!

Check your O2 sensors.... I had one go out and I started running about 9/10ths. And that's too rich for anything with only 4 cylinders. You can reset it and tiburons go to a fifty fifty ratio, but getting a new one will probably work best...
