I have a 94 accord Vtec 5-speed I dont know if it is an lx or ex. THe rpms keep going up and down from around 1100-2500 when idling. and it makes driving unusual because when no gas is being pressed it wants to jerk a little from where I think the rpms are surging. I did a search and came up with bleeding the coolant.(but i dont know how so i need to know how to do that?) and to check the idle air control valve. I took the valve off and it was dirty so i cleaned it and it is still doing the same problem. I dont know how to bleed the coolant so any info on that would be great. ALso what sensors might need replacing because i am confused, and really aggrivated at this car right now. Thanks in advance
