I recently rebuilt my computer cus it went bad but now I have a high surging idle from 1500 - 2000 rpm repitively if it's in park or neutral but if it's in drive it'll stay at a constant 1400 and if you try to drive it'll sputter and stall out if you try to give it much gas..... Has anybody else experienced this? Anyone know what it can be?
