The car has low compression.What does that mean and how much to Repair?

The engine and radio shut off normally, but windows and sun roof still operate if i push switches and steering wheel doesnt adjust up. Will this use battery over night if I am not in car and door is shut?

when the car starts it run perfect then just stalls out like I turned the key off? there are no codes being stored in the ecm!

My car goes constantly up and down like this when i accelerate, as if it is changing gears back and forth.. what coulld be wrong?

Called shop they wanted near $500 to replace the sensor. Went to local repair shop, he disconnected battery got me a new gas cap and advised to make sure you place cap on secure (like turning well past it starts clicking). Went about nine months light came on again, disconnected battery, turned cap tighter and still has not come back on.

Ive also replaced brake switch,the door settings for the seats dont eork

run battery down over night
