I have a 98 base prelude and it was burning almost 2 quarts of oil a week so I decided to fully rebuild it. I bought an entire rebuild kit, a spare head, and a skunk 2 intake manifold. I tore it down and rebuilt the motor then when I start it the car is just blowing white smoke, and after the motor goes through its warm up cycle the idle starts to jump up and down from about 1400 to 2000 RPMS. I need help figuring out this issue and fast. Any help would be greatly appreciated.
