1992 toyota p/up,22re,manual trans,a/c. at times after sitting(any length of time) it will sputter and has a great loss of power. i hold the gas pedal at one position till it suddenly will get power (like someone hitting a switch) and runs great again. there are no trouble codes and i have tested most sensors and cleaned all the grounds i could find. also,recently the injector o-rings have been replaced (# 1 & 2 were sratrting to leak).
Sounds like you have a flat spot in your acceleration, I had that but my car also had a carby. Your car has injectors, So maybe they need to be cleaned. You can take them to a specialized place that can do this, but never attempt it your self or you can destroy the spray pattern. Could be a fuel filter that's blocked too.
