First post and I will try to start off with a good one. I have a 04 QC that i recently blew up 2 pistons due to detonation, number 7 and number 3. I did a complete rebuild of the motor with new pistons, new heads with 6.1 exhaust springs, 6.1 pushrods, new timing, oil pump and a comp 260 cam. I am all in on running 91 octane and am running the SC performance tune or 91 tune. Truck has been running good ( not sure I gained a ton of new HP yet) but happy.
Here is the issue. The truck will start and idle fine 90% of the time. Never had a issue with cold start (overnight) or with a quick re start (ie running into 7-11 for a drink and back) However if truck sits for 10-20 minutes and you try to restart it almost kicks over than just cranks away. can try to crank a second time and continues to crank until you give it 1/4-1/2 throttle. Also note that the idles is random at this time but settles back down within a few seconds after starting. Ideas?
Thanks
Shawn
