Guys, im new here. need your help. I have a 1993 corolla XE 12Valve carb engine. When I start the car the idle goes down and engine stops running, i need to step on the gas pedal to give more gas until engine is warm. After running car for few mins, idle is somehow stable, though still rough. have already replace the spark plugs. can you guys help me out with some suggestions. Also, need also a copy of repair manual, can anybody provide me? it will really be a great help. thanks.
