I want to replace my ignition coil, which one do you recommend Tahoe 5.3 2007

[DJPoertsch]

Hello to my friends here at the forum.

As i wrote above, I plan to replace my hole 8 ignition coils in my Tahoe 5.3 2007. Because if it is rain outside, and I start my Tahoe I can feel some soft shaking at my steering wheel for some minutes.
I had already changed the spark plugs to NKG Iridium about 51000 km ago, but I also want to replace them again. I drive most with LPG and there for a shorter Replacement time are recommended.
But the main reason are the ignition coil. They are more than 150000 km inside my Tahoe so I Think i should spend him some new once.
So, which one you would tell me that I could buy? I found some on Rock-Auto (Brand "Standard Motor Products") also on eBay, some High Performance from REV in Red. So do you have some other ideas which one are good or should I take them on eBay. Because if I order from Germany, I have to hold in behind tax and toll costs.

It would be nice if you can help me to make the right decision, or writing me which once you use and what kind of experience do had with them.

Thanks a lot Markus from Germany.

Square shaped coils: https://www.rockauto.com/en/moreinf...CxdHWXUOBRyv5uYB2c0toC2iqw8CVkQhWw1dmSdbkwijx

I would stick with AC Delco or Genuine GM or Denso. Not Standard. The originals lasted this long, why change.

+1. I have 350000 km on the originals in my 2007 and they're still working fine. This is a part where OEM is hard to beat.

I'm also inclined to think it's something other than the coils in this case. In the old days of distributors and wires, there were reasons to suspect the ignition system as the fault source of rough running in the rain. These days, there are many other possible culprits including the MAF.

What about the plug wires, have you changed those yet? If not, I'd do those before dropping the coin on the coils.

I am with you. I think I have to test first others before spending the money. I will see why it is only at the wet weather condition. It is not a ruff riding only you feel that he will not run as smooth as in the morning. Because at night he stays in a warm, dry garage. I will check first with my test software if I would get any codes shown. I think the problem woul be with my Spark plugs. Because LPG the lifetime is much shorter as regular gas. I will spend him new once and order also some new plugs. But i ha already change them to some with a lifetime warranty. I will check if I see something on the head of the plug, so I could see with one could be the defective one. Thank you for you’re answer.

Thanks for the information. I was change them I think 40000 km ago. As I'm answering before, I will first order new spark plugs and for safety also a full set of wires. So i think in case I Drive with LPG maybe a spark plug had a defective. But it is not that you feel it hard. It is only a light vibration in the steering wheel, and it feels that it runs not as smooth as in the morning out of the warm garage. Thanks for answering me..

Hello everyone. Since my topic is still topical and I probably have a defective coil here, I wanted to attach a stamp again. What do you think of the NGK 49471 Performance Ignition Coils? Can you also recommend them? At least they are almost 20 euros cheaper than GM.

Thanks Markus

The cold start issue sounds more like a lpg system not enriching the mixture for cold operation.

NGK is an OEM supplier to GM for ignition components, so I suspect they will be good coils.
