foot on the gas to go if mash it to

could be bad gas, spark plugs not gapped properly. Bad MAF sensor or the oxygen sensor going bad.

Dirty or faulty idle air control valve and or dirty throttle plate.

I( think you have a gas problem probably caused by a vacuum forming in the gas tank which is happening because of a bad gas cap. Try running with no gas cap. If it still is bad, make sure your catilik converter is not plugged up making you lose power. Good Luck,

Since u don't say I m guessing u have a 4 cylinder. the ignition module is under top cover and were prone to failure due to heat. ihere is no way to check them that I'm aware of. Have to swallow hard and take a guess
