Engine sputters and CEL on
 

Hi all!

Wife's 09 accent sedan started sputtering and the CEL light blinked about 15 times before going solid. It acts like a misfire....

Did not get the codes yet but any ideas or pointers at what I should look at?? I hear they are prone to coil failure...

Thanx!!

Gotta get the codes. Could be anything.

Got a code reader on it....and despite having the CEL on, no codes....

What kind of reader? If the Check Engine light is on there should be a code. The other possibility is a problem with the computer itself.

It's a U480. Buy U480 1.5" LCD Universal CAN-BUS OBD2 Car Diagnostic Code Reader Memo Scanner

I know...it's a 20$ thingy, but works great on other Hyundais I tried....I can erase the code, but it reads ''NO CODE''. And the CEL comes back on after like 3 minutes... Looked at a few things today, looking for loose or disconnected wires, vacuum, etc etc. Found nothing to be out of place. It's -30C here today so I ain't crawling under there fer sure!!

I guess I'll have to bite the bullet and get one of those ''70$ diagnostic'' from my mechanic....

Well.... 2 coils later, and 289$ including diagnosis, labor and parts. She runs like new!

That wasn't covered under the warranty?

I'm over 100 000 km.

And guess what....on the way home tonight it did the same thing again! Back to the shop it goes tomorrow!

Both other coils gave out, and did the spark plugs while we were there. 209$.

So total for 4 coils, 4 plugs, diagnosis and labour: 498$
