"I had a rebuilt motor put in.
"I had a rebuilt motor put in. It ran fine for 10 hrs. It then started to loose power. I was unable to give it full throttle, it would bog down. I stopped and shut the motor off, when I restarted I could barley get 2500 rpm while in gear. I could throttle up without it in gear, but it would still bog, I could get about 4000rpm. When I go to start it, it fires off then dies, it does this about three times, then it runs, but the idle is not constant, like its searching for somthing. I had codes read and they said map sensor. that was changed no difference. Timing is set. and fuel filter has been changed 3 times. Fuel pressure with key turned on is 20 lb. With engine running 30 pounds. Could you please help?"
