Now for the P1338, is there any tips you guys can give me on how to check the sensor? just replace it? also where in gods name is it ? And what is that G40 # that keeps being repeated in that section.

And for the P1136, i would assume start with the MAF clean it its, check for damage, also replace fuel filter. Whats the best way to check the others? Any other tips from people that had similar problems iw ould love to hear them. THanks

 

For P1136, start by checking all the vacuum lines.
