afterputting new intake on 2 weeks ago and setting the timing at 14 the car had extremely high idle 1200.i ran it this way a week and finally decided to adjust the tps.when i adjusted tps idle came down to normal,but it started over heating before i even made it back into the car.checked coolant level,slightly low,so i filled it up with car running so there wouldnt be any airbubbles in the cooling system.drove the car a few miles,and all was good.on the way home it started climbing.got up to red on needle.pulled over and intake was ice cold,radiator was hot all the radiator hoses were hot.i tured on heater to bring temp down,no heater.blew cold.tuned car off,let a little pressure off of radiator cap and intake got extremely hot.then you could hear the fluid running into the heater core and heater got hot.after letting pressure off it got cool enough to drive home.coolant again was low.refill and starts again.no coolant in oil please help
