Devils88 Neutral Newbie March 13, 2012 Share March 13, 2012 (edited) Hi guys, I need help.. Very recently, my 06 sonata give me problems. Ytd while I was driving from Bukit batok to Suntec, midway there, the engine starts to vibrate and keep dying when it is idling in jams. I restarted my car alot of time and the same cycle keep on repeats itself again, and the engine checklight keep blinking. After 3-4 mins , the condition start to improve, so i drove it down to komoco service centre at alexendra road, nothing happen while on my way there, it was very smooth(no engine light, no vibration etc). At komoco motors, they did a dignostic check and they change my spark plug as they tell me it causes the problem. So, i let them change. I collected my car on that day and no problem surface up during my journey home. But this morning , while i was driving, the engine checklight come out again ( but no vibration and dying ), i was worry so i drove the car back to komoco again. After they did a error code check, and they found out my cataylic converter is damage and causes the checklight to come out. They told me in order to replace the catalylic converter, i will need to wait for a week or 2 for the stock to arrive from korea and the replacement charge is 2k excluding labour. Right now i am very confuse, i called up my friend and he told me it was due to i pump the nearest shell near woodload causeway malaysia petrol and he told me his audi has this same problem before. My friend also recommend me to pump full tank singapore petrol and monitor the situation. After that i called up komoco and verify but they say it is not malaysia petrol that causes this problem, they told me it is due to high mileage of my car. My question now is should i listen to my friend and continue driving with the engine checklight on or should i change the cataylic converter? And does anyone encounted the same problem as me before and can share ur experience with me?

Colin03 4th Gear March 13, 2012 Share March 13, 2012 you might considered to have your cataylic "knock-through" to resolve this issue - too much carbon . What is your mileage ? Link to post Share on other sites More sharing options...
Versatile 1st Gear March 13, 2012 Share March 13, 2012 Which part of the catalytic converter located at? IIRC, most CAT will be at header, midpipe and exhaust. Link to post Share on other sites More sharing options...
Bigbadguy 1st Gear March 13, 2012 Share March 13, 2012 Think you can get a cheaper deal at scrape yard, Since your car left about 4 years and its not worth changing a brand new one. An average midpipe cost about 300, a sonata should cost around that range, maybe 300-500. Link to post Share on other sites More sharing options...
Trex101 3rd Gear March 13, 2012 Share March 13, 2012 I would suggest go to any exhaust shop and get it knock thru and be done with it. Save $ and increase power somemore Link to post Share on other sites More sharing options...

He say the manifold inside the cat is damage, need to replace whole cat! Go to man exahust at sin ming or fong kim at ubi to help you to solve the problem. There are specialist in exhaust system. If you want piece of mind. As what some bros here mentioned. Get from the scrap yard it is cheaper than replacing new which cost you 2K exclude labour.

Dennistan80 Neutral Newbie March 13, 2012 Share March 13, 2012 Replace with a performance extractor and keep the original extractor for inspection for cheaper solution. Link to post Share on other sites More sharing options...

He say the manifold inside the cat is damage, need to replace whole cat! bro, u said yr cat is located at the exhaust... Is it the muffler? Most are after the down pipe before the mid pipe... and there is usually a second O2 sensor there to monitor the cat... Can it be the sensor faulty? Pls visit any reputable exos shop for 2nd opinion first i think... Link to post Share on other sites More sharing options...

Chances of the insepctor go and tap is very slim. Because the exhaust is hot! Link to post Share on other sites More sharing options...
