[ARCHIVED THREAD] - Rough start and idle with '01 Hyundai Accent

Posted: 8/16/2007 4:25:43 AM EDT

Over the last month or two it has become harder to start in the AM- turns over, catches, idles roughly , quits, repeat. When it finally iddles I can't step on the gas for a few minutes, otherwise it sputters and dies.

On the highway whatever pick up it had is gone-going uphill the pedals to the floor to maintain 50 mph at best.

Anyone have an idea what it may be? I was going to replace the O2 sensor this weekend, but wanted some ideas on what else it may be.

TIA

The first thing I'd check would be a fuel pump dying. Normally if one starts to go, it doesn't last as long as yours has, but it's worth looking at. Try cycling the key on and off 3-4 times before you try to start the car. Leave it in the on position for 4-5 seconds before turning back off. This will engage the fuel pump and should help build up some pressure in the rail.

Sounds like it may need a basic tune-up. How many miles? How old are the plugs and wires? Consider the basics first. That being said, I'd get it read for codes before I started throwing any parts at it.
