sounds like a evap problem. yours should be close to the same as this. only difference is the soloniod location on the 3.4

thx i will post results

 

ok i took a lil break from the car for awhile so i got codes now code 34 36 13 35 22 and 82.the weird thing is it doesnt start when nothin hooked to it.but when i leave the code checker in and turned on the car runs great with no problems.when you run the code checker does the car go into a daignostic mode ?

 

the ecm goes into field service mode and i think it will stay in closed loop. no closed loop timer. you may have the ability to switch from closed to open im not sure of that or how its done. the number of codes and the sensors involved im thinking the ecm connections or the ecm itself has issues.

 

so far this is what i have.
