*****Troubleshooting,please help!!!******** My car is starting to have a missfire.In the morning it worked very good but when i drive it for more than 1 hour it star a very BAD misfire.In the highway in 6th gear it fail very bad and the srev, engine soon ligth start bink so i know it is a missfire.Then if i stoped the car for about 20 minutes the problem desapired until it getting hot again. 
I think it can be an ingnition coil.What you guys think.Any of you had the same problem in the past?If so what you did to solve it?Thanks in advance.

Have it scanned for error codes, post the results here.
The stock LS1 ign coils are very tough, unlikely it's one of them.
The only times I've had a noticeable misfire were traced to an oily MAF sensor (got code P0101) and a worn out plug wire (got code P0200).
Start with the stored error codes.

Definitly is a detonation issue.Is any way i can read the codes with out an scanner?If not the HP tunner can be used to read codes as an scanner?If so i have the excuse to buy it.
The plus wires are about 10 month old MSD,spark plugs the same time TR55s.So i have to find out wich code it give me.Thanks
