Bought used with 65K on it. Recent problem after completing 60K maintenance (timing belt, 2 other belts, plugs, wires, changed tranny fluid). Ran fine for 1400 mile trip and return home after a few days and suddenly engine is missing at idle. Codes say 1,3 and 5 are the problem. Could it be a bad sensor? Fuel pump? My mechanic who did the maintenance is stumped so far.

Any help would be greatly appreciated.

Turns out that the timing belt had jumped three teeth for absolutely no reason. My mechanic reset the belt and it appears to be running fine. Thank you guys for all your suggestions.

Hello. I need to know the name of the part that is on the circle on the photo below.
Vin# km8sb82bx1u031763
Someone cut the wire and i don't why.
The came from the ignition misfire (failure) sensor. That wire came from the tan/black wire to a plug and change to a black wire and ends on the bolt that holds the same sensor. There's another photo showing the wire with the x mark the sensor, the circle the cut part, the arrow where the cut part suppose to be.
If someone know let me know i want to know because i want to finish the wire harness.

Hi,

I believe you are referring to an ignition misfire sensor. Take a look at the attached pic and let me know if that is the part you are referring to.

Hello. I'm referring to the wire that comes from that sensor. If you see on the photos i send i mark with a circle the part that is missing on this wire harness. I found the part# of that wire harness.
On the photos i mark with an (x) the plug with and without the ignition misfire sensor and mark with an (o circle) the cut wire and what i think is a capacitor, the part that someone cut.
The wire came from the tan/black wire from the ignition misfire sensor and change to a black wire that ends at the ignition misfire sensor like as you see on the third image mark with the circle
Thanks,

Hi,

That is the ignition condenser. It is Hyundai part number 2732538000. You can get one aftermarket. I believe Dorman makes one.

I attached a pic below for you to confirm I have the correct part.

Let me know.

Thank you Joe.

I ask you, what's the purpose of this ignition condenser and what problems can cause if don't have it? Like in this time.
Thank you.

Hi,

The purpose if a condenser is a place to put excessive electrical power. It functions much like a capacitor and the two terms (condenser/capacitor) are basically the same thing. The word condenser is not used as often anymore. Without it, electrical components (in this case ignition components) will not last as long.

I appreciate your help Joe. I found the capacitor at a good price original from Hyundai.
Knowledge is power.
Experience show that knowledge.
