1998 Sonta Stalling occasionally

ALSO..according to my manual, the relay for the fuel pump is located bottom side panel on the passenger side.. this is a multiple relay that shuts down the whole MFI.. is there a separate relay?

Visit your local parts tore, such as Advanced Auto, and they will hook you to the computer for free. That may tell you what you need to know so you don't blindly throw money at it. Even new plugs and wires can go bad.

Thank you Ed, I see you're still around :) Hyundai tech, mike?

Dave;

I'm not sure if you have been following my posts and similar issues with my wife's 2003 Sonata. I have replaced the plugs, wires, lower O2 sensors and the coil pack. Still the problem persists. I'm at the point now of replacing the MAF. $49 from Ebay- OEM quality, 2 year warranty. BTW- Same MAF-

1998 Sonta 126k~2.0L Hello everyone. It will sputter & stall in and out when restarted from short trips (2-8+ miles) BUT, not always and will eventually stop sputtering It FEELS as if:

-Plugs and ignition wires were recently replaced

-Last 3 years I've been averaging ~3,000 miles per year. Once or twice a month, I've been driving her 20-30 miles nonstop at highways speeds.. .(charge up the battery, remove any moisture, clean out her pipes, etc.)

I just got a fuel filter, but the darn thing is tight as heck! I spayed liquid wrench over night, I'll be getting a new flare type 14mm open end wrench this week and hopefully it will have a much better grip. Next on my to do list is the fuel tank strainer ..

Money is tight.... Any help is greatly appreciated. Dave

No trees were killed in the sending of this message. However a large number of electrons were terribly inconvenienced.

An alternative: if you have a buddy who has a code reader, you may be able to connect it and see if the computer's registered the same codes. I'm saying this because I know that one or two auto parts chains offer this service, but their local stores in my area do not.

I realize this has been quite a while, but if you're still hunting the problem, some more information may prove helpful.

We need to determine whether the engine stops running. What do you mean by "stalls in and out?"

Sputtering often indicates a misfire or low fuel pressure. If the ignition on all four plugs fails, your engine will stop running immediately.

Does the issue occur while driving or when stopped?
