What are your modifications if any? I'm mostly interested to see if you have a UDP.

I had the same problem....ended up being the spark plugs. I put in Ngk tr6's when I put on the Trickflow heads....using anti-sieze on the threads. Replaced the plugs with new tr6's and no anti-sieze = no more issues. One possibilty for ya.

I also have this problem. Fortunately I purchased an extended service plan. To see the life of your battery, open CMD prompt as administrator and type in "powercfg -energy -output c:\energy-report.html" and when the report is finished, open your browser and type in the address given... for me it was c:energy-report.html

My battery currently holds about 37% capacity @ 'FULL' charge, and this is just over a year after buying it.

Yep, anti-seize is old school.

May be necessary for iron heads...but not aluminum. Can also allow you to strip out the threads in your nice alum. heads. That would be a sad day in Mayberry

Wait a minute, I'm not sure what your complaint is?? Although you say you have a new battery and alternator, I'm a EE and even though I may not have the answer, I really don't know what your problem is....can you be more detailed as to what is abnormal?
