Went into town and after about 30 minutes of driving with ac on high at a stop light, truck just died. Put it in park and started it back up. Started fine, drove away fine. Did it again after a while. Didnt do it every stop. Noticed too my idle is low, is there a way to raise the idle? Its below the 500 mark or at least it was when i noticed it after it stalled and everything.

 

ok so the cel cam on about 45 min later and just figured it was the po441 incorrect purge flow thats been coming on,and it was but there was also a po108 code i just read. Whats this code? How do I go about fixing/testing? Thanks

found the code

"MAP sensor input above maximum

acceptable voltage."

Is this related to the po441

"Insufficient or excessive vapor flow
detected during evaporative emission

system operation."

 

Check canister under frame and gas cap.

 

Yea ive been meaning to do that for the reoccuring po441 but would that also trip the po108? Or is the bad map tripping the po441? or are they totally seperate?

 

Can't say for sure. Have never had any emissions related problems.

 

so is the map sensor part of the emission system?

 

MAp is on air intake. Do you have the service manual from the FAQ/DIY section? Free download. never had problem with MAP pr MAF on any vehicle either.....(I roll with big stuff - like blown tranny....) You can pull the MAP and clean. Disconnect battery negative first.

 

yes i have the manual but it doesnt say if those codes are any way related. The light came on and i scanned em same day so the codes more than likely were thrown at the same time. Ive had the po441 come on every once in a while but the map one is new.

 

I don't know enough about how the PCM is programmed but they may not be related. Only experience I had with anythng similar was step son's Taurus and all the EVAP system hoses were rotted. I woudl treat them as separate and check out each system. Don't know if there is a way to check MAP sensor or not. Maual should say if there is. I hate to just swap parts and hope...especially with other people's money!

 

what do you guys think about this for the map sensor code i got? its about $50 cheaper than the auto store and says it fits....
