Subaru Legacy 2001 AWD sedan stalling
I am having some issues with my Subaru Legacy 2001 AWD sedan. After driving for a bit, the engine starts chugging, car starts shaking (seems to come from drivers side) and if I continue to drive it smells similar to burnt rubber and the engine dies. People have said it might be the fuel pump, a timing issue or the computer needs re-flashing because of the new battery. I'm at a total loss and I need my car for work but I can't afford to put much money into it (about $1000 at best) It doesn't have any issues when it's just idling, only after driving for about 20 minutes (even less as time goes on)
Check timing belt for condition and slack.
