But then outof the blue BOOM it fires right up and runs like a top! Im so baffled. It will start for a week and runs smooth as can be. Then all if the sudden after it sits for a few hours it will go into one of these spells again. It will just crank and crank for a good while. Like for 45 minutes I can crank it with no fire. Then as I said out of the blue it starts up and runs like new. No hesitatation, no misses, no sputtering! I have changed the shut down relay and I thought it cured it but it started acting up again this morning. I don't think its a map sensor because it runs so smooth when it fires up. Any thoughts would be appreciated!
