after the car warms up it idles around 900 to 1200 rpms it also sometimes goes up and down but doesnt sound like it is missing. the rpms also go up while im pushing in the clutch to shift during acceration it seems as if it sticks while im shifting. i just bought the car and i dont know much about it other than the car has alot done to it. under the hood there is no mass air flow sensor there are rubber caps on the throttle body vacume tubes (i believe they are vacume tubes). no EGR valve the is a fuel pressure regulator but no gauge. i think it has something to do with the vacum or idle air control what do you guys think i should try?
