i started my eg coupe after doing the teg dash conversion and at first the idle started jumping up and down about 500rpms and now the car will only run for about 15 seconds before choking itself out and dying ive heard this idle problem can occur if you get air in your cooling system which is highly possible sice i did have the hoses off to swap out the heater boxes but now the car wont run long enough to bleed the cooling system if anyone knows how to fix this please lemme know
