My 94 accord this morning when I first tried to started it turned over slowly as if the battery were almost dead. When it started the D4 light was flashing quickly and it was running ruff. I turned the car off and restarted it. The engine still turned over slow but started right up and was running like it always does with no flashing lights. Since then I have driven the car at least 70 miles,have shut it off ,let it sit and started it at least 6 or 7 times and it has run fine and while starting, the engine turned over quickly like it always does. Any ideas on why this happened this morning? I remember about 2 years and probley 50k miles ago I stopped at a stop sign and the engine started running ruff and the D4 light started flashing. At that time I drove it home and the next time I started the car there was no flashing D4 light and it has run fine ever since until it did it this morning. Any ideas will be appreciated. Thanks
