Default Hard to start when warm???

So i got in my car the other day and drove to a gas station, i fueled up, got in and i got a slow crank, it just kept cranking, so i stopped, waited a few sec, same thing. after about 4 attempts it finnally started and it went to about 1500 rpms held there for a few seconds then went back to normal idle. I also noticed this yesterday, not as bad, but same deal.

only thing ive done to the car lately was a small cam install LPE gt2-3 (207/220 duration @ .050 .573/.580 with 1.7 ratio rocker arms 118.5 CL)

car has been driving fine since i put it in, ive put about 400 miles on it since the cam swap. also changed the pushrods and valve springs to patriot golds.

i talked to speartech today, they said its most likely not in the car being untuned, but maybe fuel related. Ill have to check it out. if anyone else has any info that would help, please let me know.

I found the problem, it was a sensor next to the headers on the drivers side, anyone know what it does? it got broken off, so i fixed it up, no startup problems now.

thats the engine coolant temp sensor.Very important to be working right. I cracked mine changing the spark plugs once. didn,t know until I was at the track, on a hard launch it just died off the line, lol. I think they are only 25$ or so.
