Well I replaced the MAP sensor and after a trip around the block the light went off, but 5 minutes later cameback on . I also noticedit hesitatessometimesafter a stop (red light or stop sign). I also changed the air filter and PCV valve.

What should be my next move? The p0107 code also mentions the Mass Air Flow sensor as a possible cause. Do I try this or stop wasting money on parts and take it to a shop?[/align]

 

Check your air filter first, sometimes a dirty air filter will result in "MAF or VAF low voltage/low response" and make it run rich.

 

Brand new Fram air filter was put in at the same time as the MAP sensor.

 

Search this site for MAF cleaning-you can do it and cost is only time and cleaner. Does the cat. converter rattle? Had one or two of these where it kicked this code but ultimately had a bad cat. good luck JP PS may have a bad MAF but cleaning it first is the route to go and we'll go from there!

The diagnostic procedure never mentions the MAF sensor...

Now this is why I always advocate of proper testing prior to component replacement.

Here is one thing that sticks out at the tail end of the diagnostic procedure linked to above:
MAP = Manifold Absolute Pressure
FTP = Fuel Tank Pressure
TP = Throttle Position
EGR = Exhaust Gas Recirculation

 

the reason I mentioned MAF sensor was because two previous posters mentioned the MAF as being in the loop. Thus the cleaning..I did not look up the code myself. JP

 

I really was not responding to you JP, but to the OP. I should have clarified as these stupid "(in reply to xxxx)" tags are useless when you do a quick reply.

 

I am taking the truck to a local repair shop tomorrow. Thanks for everyone's help.

 

If you would...let us know how you make out. JP

 

I will for sure.
