ya dsmuts theyve been done already and 99pontiacgp are you talking about running it with that cracked vacum line will cause it to overheat i keep a check on everything but the low coolent light is on the service engine line does sometimes,im gessing because of the line and the airbag light does sometimes and pass key does but it runs good and sounds normal and ****s a lil bit hard when first taking off but my gp does that i can just feel it idling from the inside,and i plan on keeping 10w30 oil in it or whats the best that will make it last a little longer and should i leave the trans alone or drain it
