Hyundai Elantra 98 engine stalling and sputtering

[Sidharth Kapileshwar]

I own a '98 Hyundai Elantra, 5 speed manual transmission. In the last one or two years, I have faced a problem when sometimes the engines just seems to stall, sputter and then die out. The check engine light comes on.

This happens typically when I reduce the speed for making a sharp right turn, for example. Or, when I am starting the car getting it to cruise from zero speed. Sometimes, it also happens when I am in the middle of a cruise, say at 40-45 mph speeds.

Also, the problem seems to be a lot worse during the summer months. The temperature seems to have an effect, and high temperatures seem to worsen this problem.

I took it to a mechanic and I was told that it could be because oil is leaking into the air filtration system and confusing the sensors.

Does anyone else also experience the same problem? Any suggestions on what may be wrong, or how to fix are highly appreciated.

Thanks.

Have they checked for DTC's and are there any?

Thanks for your reply. They did check for DTC's and I was told that there are none.

I supposed you did the typical things such as changing the fuel filter, etc. Sounds a little like starvation... but then my experience on that sort of thing dates back to carbs vehicles.

I don't have any guesses with a high enough percentage to mention. At this point, you're still in the could be just about anything scenario.

How about changing spark plug wires and plugs itself. It seem as high voltage is breaking down somewhere.
