HELP head gasket and wont start
i dont know if the problem is related but a few weeks ago my throttle stuck and i drove home about 5 miles in 3rd gear with my foot off the gas. i just wiggled it when i got back and everything was fine. starting from here on out also took a while and the engine would shake and buck until it started. then driving about 100 miles my heater stopped working about 50 miles in and the thermostat was under C. when it cooled i checked the radiator fluid and it was almost empty so i filled it back up and when started and revved the temp went back up. drove home without any problems. then on a 500 mile trip my heat turned back off and i stalled out in 5th gear doing 75 on the highway. when i stopped i filled up the empty radiator and continued on my way. i attempted using Blue Devil radiator and engine sealant but some how managed to lose most of it onto the floor. before it went in but it helped for a while. driving 500miles again i started bucking every time i went over 65 and had no heat. this time my radiator seemed to be almost full still. i let the car sit for 24 hours and now it will not start. i almost drained the battery trying. i have noticed bubbles coming out of the overflow tank. im assuming its the head gasket but i have never seen anything about not being able to start with a leaky or blown one.
