Updating on this.

Replaced the Coolant Temp sensor and that is now working properly. Car now runs at the 1/4 mark or just a hair above. Has been consistent for about 250 miles now.

Also, the warm start issue is also fixed. Put the MAF on from my Bonneville and the car is now starting perfect while warm. The new MAF I installed must have started malfunctioning and caused the issue.

Thanks for all the help! Car runs as new, not like it has 206K!
