Hey guys, it seems like my truck is wanting to try to start nickel and diming me. I had Chris Snyder do a head gasket and some head work last week, which he did an awesome job with. Anyway, yesterday i went to go eat lunch and when i came back out about 40 or 45 min later and got in my truck to start it, it started like normal, within about 1 or 2 cranks, however when it fired it didnt ramp the RPM up like usual and it idled kinda low and "rough" (could just be from the low RPM) but anyway, it died and i restarted it and it stared like normal. Did the same thing again last night after about a 15 min shut down. Seems like it only does it after a full warm up of engine and a short shut down time. Wont do it if i shut down and start right back up, wont do it if it sits over night. Any ideas guys?
