Well, I was lucky enough for them to replace the HG on the 99 I just bought for 7k with 48k miles under the warrenty, they serted it too. Everything seems great, I smell a little coolent but I think it's just remenents burning out of the mufflers from when the HG was bad, I only drove it around 50 miles since the replacement. The car pings now on start up when it's cold, it goes away after a minute or so. I'm not sure if it did it before the HG replacement because I didn't have the car long and it wasn't that cold. I tried to WOT a couple of times and it made some noises (not bad sounds, I think it was and is making noise because she was never wot before, some old guy own the car before me and it's mint). The ping is still there but I can't tell if it's gotten better since WOT because of the outside temps have change some much here in NJ. Should I be concerned or content that I have a 99 that runs like a gem? Is there an additive I could try? Should I keep on WOTing for a while (I dont to break it or blow the HG)? Should I take it back to the shop or just enjoy. Thanks for all the support, love my car.
