Unstable Angina and Non-Q-Wave Myocardial Infarction: In patients with unstable angina or non-Q-wave myocardial infarction, the recommended dose of Lovenox is 1 mg/kg administered SC every 12 hours in conjunction with oral aspirin therapy (100 to 325 mg once daily).
A vehicle's fuel intake system pumps fuel into the engine. If it gets clogged or starts to leak, an insufficient amount of fuel can cause the engine to shut off without warning. Finally, the vehicle's electrical system provides the spark necessary to ignite the fuel and power the car's engine.
One thing you can do is on a cold morning when the car is cold, start the car and listen for the whine of the air injection pump. It should be on for 30-45 seconds and then shut off. If you can't hear it, tell your mechanic that. You can trace at least the lines to see if there is an obvious loose line or an air leak.
