Guys,

I did have the same problem yesterday. After reading this forum, I finally replaced four ignition coils today myself; however, after I turned on the engine, the check engine light was still on, but my car didn't vibrate anymore like yesterday.

I am still worried about the check engine light still on. Any suggestions will be appreciated.

Thankss

 

Check engine light is still illuminated because the misfire codes are still stored in the ecu. Have the codes read, and cleared, and you should be fine.

 

Hi Jordon,

Thanks for your prompt reply.

I also noticed some sparkling sound when I turned on the ignition. I was sure that I had secured all the coils in place. Why there is that kind of sound? I did turn on the engine for 5 minutes, and there was nothing happen except for that check engine light.

Could it be possible that I got a different type of coils from the store where I bought them? I did tell them my car's model and VIN#.

Please advise on this. Thankss

 

I can't think of any reason new coils would cause a sparking sound..... Can you locate the source of the sound? Also, scan for codes...

 

Thanks for the reply Jordon,

I will try to drive it today. I still have no idea what that sparking sound is. One thing that I noticed last night from a video on Youtube is the coils need to be pushed deep enough until they click in. However, I never heard that clicking sound while securing the coils. Could it be because I didnt press them hard enough?

 

that could be the cause of the sound ur hearing.. Its probably arcing since its not pushed all the way in. You'll need vagcom to reset the code to clear ur check engine light.

 

they do not click when pushed all the way in. Your plugs are probably not gapped properly.

 

Look under the hood in the dark and see if you can see anything sparking.

 

THanks guys,

Today I went to see a mechanic. He told me that my car was fine. The sound was actually from the ABS panel. That sparking sound was from the ABS computer checking the system when the ignition is switched on. Do you guys experience the same thing?

After disconnecting the baterry for a few minutes, I took the car for a drive. Everything seemed fine. The check engine light didn't come on anymore. The only thing that I noticed was the digital indicator showing fuel consumption keeps fluctuating dramatically. I used to see 15L/100km, but now it seems to fluctuate a lot below or above that. At once it showed 2L/100km, and suddenly it showed 22L/100km.

Do you think there is something wrong with the trip computer?
