No offence Mitch, but it seems you're a little stubborn. I don't know your exact situation but it seems you have no job, no source of income yet you seem to be constantly tinkering with your car which costs $$ and ends up costing you more $$$ with problems like a defect. My advice to you, and please don't take it the wrong way is to sell the car, get yourself back on your feet then look at buying another car. It's not worth running yourself into the ground over, cars can always be replaced mate, your sanity and financial well being on the otherhand can be a little more difficult. It's a simple case of trimming the fat. We all know these cars are expensive, do the math, I think you'll come to the same conclusion too.
Just me friendly advice, take it for what it's worth
