ok i can hear the leak just dont see it i will go out and look the whole system over and see if i can fine any leak and fix it then will see how it is

ok i have check the whole exhaust system out and fixed the leak i found no change in the idling problem so i pulled the spark plugs out one at a time check gap and i did notice that other then carbon up bit they were all wet with gas i think

Still idleing problems
 

Yesterday i checked all the plugs and gaps all good started it it idled fine till at operating temp then it died and hardly idled this morning i tried to start it it started but wont idle , and it is running rich i think from the black smoke that comes from the tail pipe what could be causing the problem

Have you tested the MAP sensor? Search for "MAP+voltage+altitude" with an author of "swartlkk" and you should find the relevant results.

i tryed looking for it could not find it does it explain how to test the MAP also

thanks i will test it and see what happens

i have tested the map it seems to be ok i was rechecking the fuel system and found a small fuel leak on a line it did not sell of fuel or drip but i did check and it was fuel would that mall leak cause all this problem ? I did not see the leak at first a friend found it while helping me

I have fixed the fuel leak it spit a bit and died at first but then ran for 1 hr before dieing again it spit and sputtered then died and other ideas
