I've had Civics for many years now and one thing I've had to replace on every one of them has been the battery... The rest of your problem could mean the car just needs a tune up... Take it to a trusted mechanic and have it tuned up and replace the air and fuel filters....Hope it helps cuz they're really fun cars to drive.... Just sold my 1992 Civic LX sedan and I miss it... Still have a 1990 Civic Hatchback that's dedicated to my kids learning stage...
