Fixed egr vac sys on 98 hyundai sonata 3.0 v6 now engine runs rough


It sounds like a vacuum problem is keeping the EGR valve open causing the other sensors to read this and more fuel would be injected by the ECM. u may of gotten an egr code but the problem is not the valve itself.

WHERE IS THE SERPENTINE BELT LOCATED ON A 2003 HYUNDAI SONATA


Vehicles Covered: Hyundai Sonata 2002-2004 (2.4L & 2.7L Engines)

In 2003, Hyundai produced two types of Sonata:
Available engines:
4 Cylinders 2.4L VIN "S", MFI DOHC - see Figures 1 and 3.
6 Cylinders 2.7L VIN "H", MFI DOHC - see Figures 2 and 3.

To differentiate between these types of 2003 Hyundai Sonatas, the VIN 8th digit (Engine Type) will either be "S" or "H" as in the table above.

To locate the Engine drive belt, jack up the vehicle & place it onto jack stands, then slide under the car (toss a cardboard mat down first), then, once under the car, remove the (plastic) engine splash shield. Once removed, the drive & accessory belts are easily observed.

The "COMPRESSOR" refers to the A/C compressor, and "GENERATOR" refers to the Alternator.

The Belt Routing on the Left is "With A/C", on the Right is "without A/C"

Inspection - Drivebelt and Accessory Belts

Inspect the drive belt for signs of glazing or cracking. A glazed belt will be perfectly smooth from slippage, while a good belt will have a slight texture of fabric visible. Cracks will usually start at the inner edge of the belt and run outward. Worn or damaged drive belts should be replaced.

Drivebelt Removal & Installation - 2003 Sonata (2.4L and 2.7L engines)

Raise and support the vehicle.
Remove the engine splash shield.
Rotate the drive belt tensioner clockwise to release the drive belt tension.
Remove the drive belt from the alternator.
Slowly release the drive belt tensioner.
Remove the drive belt from the accessory drive pulleys.

To install:

Install the drive belt to the accessory drive pulley.
Rotate the drive belt tensioner clockwise.
Install the drive belt to the alternator.
Ensure the drive belt is properly aligned and seated into the grooves of the accessory drive pulleys.
Slowly release the drive belt tensioner
Install the engine splash shield.
Lower the vehicle.

Here's the best illustration I can find of the Hyundai 2.4L and 2.7L engines - the drivebelt seems to be located on the passenger side of both of these transversely mounted engines.

Sounds like you have a plugged up catalytic converter. You cant clean them it will need replaced. If it is the 4cyl engine, the converter is the exhaust manifold on the front of the engine.
