In patients with acute ST-segment elevation myocardial infarction, the recommended dose of Lovenox is a single IV bolus of 30 mg plus a 1 mg/kg SC dose followed by 1 mg/kg administered SC every 12 hours (maximum 100 mg for the first two doses only, followed by 1 mg/kg dosing for the remaining doses).
Hardware failures inside the engine can also cause rough idle problems and misfires. Anything higher than the crankshaft itself is a likely culprit, but that doesn't mean the bearings or crankshaft itself aren't.
Dirty and/or clogged emissions components can also cause a car to stall during acceleration. If filtering components and sensors are not functioning as they should, byproducts from unburned fuel--or low grade fuel--could accumulate, resulting in air not being able to circulate through the system.
