Ok, i noticed now that the idle will be normal 800rpms and sometimes, it will climb up to 2000rpms! i went to check the throttle body. saw under the hood on the diagram, it shows "throttle positioner", not the sensor or "tpi" but this little thing with a rubber boot on it, well, which was a boot. my problem is i dont know the exact name for the part! and cant find it since i lack the true name of the piece! maybe sol-vac? when i touch this prong on it, the idle returns to 800rpms, but when released, the idle wlll jump again. the boot on this piece was all shredded up, maybe due to age? but i need to replace it, anyone have any idea what it could be? all vac lines are ok too. also sometimes when i push the accel pedal, it feels like it gets stuck! all this only happens once the engine is a operating temp! also after driving the i restart, it will die out unless i give push the gas pedal a bit to keep it going then once on the road, it wont do after like 5mins
