Thank you all for the concern, but everything seems to be ok after three weeks and almost a thousand miles. My question is the gas milelage. How many miles do GT owners get out of a full tank of mixed driving (city and highway). and what is the recomended gap on these plugs.

I was just curious, car is fine, actually just went over 36K, so it does not matter any more, but I used to be a mechanic, and I looked it over pretty good, it's fine. The only suspicion is, whoever owned the car before did not use premium gas, plugs seem to be worn and too dirty for a toyota engine...

Hi yall, just joined the forum, just bought an '03 Satellite GT with 35K miles on it at an auction in PA, it was a dealer trade-in, want to know if anybody knows the first owner. I just want to know if they had any problems, etc.
