Yea just take it to the shop, it`s hard to pull engine vac and pull the plugs. Cleaning and testing connections/sensors are time consuming also. Testing the maf is tough too. It is like answering the other question that have been asked,it`s pretty hard to do. Try to take to Warlackk`s shop so he can make some money. Keep us posted what was wrong and how much the shop charged you.

 

The thing that I find confusing is the fuel trim reacting backward.

 

Warlockk would a bad pump or injecter cause that? The check engine light is not on but the stored code is saying po136 and po141 it's going to the shop Thursday

 

Its possible but I think it would cause a positive fuel trim.

 

Well go it back from the shop no fuel or vaccum issues!! He reset the computer and cleared all codes but the maf code came up while he was driving reset at and couldn't get it to come back on so he told me to drive it a few weeks and then stop back in and scan it again but truck is running great now no more issues on hills
