Close to 150,000 miles. Started dying at stop lights after the car has run and warm. Eventually the check engine light came on. Had the code checked at autozone and the guy showed me the screen (Running Lean). O2 sensor lean. Nothing else. I had when it started dying put a couple of bottles of injector cleaner through it no change. Can I check the fuel pressure myself? I cannot locate the tap. Can I check each injector? has anyone had this problem?
