j30 hesitation when hot

[cdaddy1177]

I have a 1995 J30 which I recently purchased with only 48k on it, when the car is cold acceleration is great, after about 10-15 min, once hot it has severe hesitation from a stop. When I push the pedal down to about half throttle it jumps up and accellerates fast. I have taken it to the dealer and they say that they cannot "replicate" the problem after charging me 200 for a fuel injector and intake cleaning. There are no error codes. I cleaned the MAF sensor and the car does not look like it is running hot (temp gauge at about 2/5 when all the way warmed up. The idle is OK and fuel efficiency is around 17 mpg average (I have a heavy foot) All fluids look and smell ok and there do not appear to be any disconnected/corroded vacume hoses or sensor plugs. Any advice or input would be GREATLY appreciated. (Some posts here have pointed at the camshaft position sensor or the coolant temp sensor, I need a engine skematic to find the coolant temp sensors location if any of you have one it is very difficult to find a Haynes manual for this car)---Chris
