If I unplug the maf it runs perfect. Plug maf in the idle lopes up and down and runs rough. Is my maf bad? 99 6.0

Possibly the MAF is just dirty?

  Notice the picture of the new 6.6L V-8? Looks like it has fuel rails on the side of the intake manufold. Either GM went back to port injection or it has dual port/direct.

  Sorry that you need these surgeries but glad they will improve your current quality of life. Do you have dates for these operations?

  I hear Ram’s ZF transmission is pretty bulletproof.

  I have A 2020 1500 5.3 8 speed. LTZ. Transmission problems since 60,000 miles. Started when I go to store in morning to get my morning coffee before work leave truck running get back in put it in drive/ rev no movement step on gas a little slams into gear. Put in neutral step on gas little shake then put in gear and gose. Shut truck off start .. ok now at stop light stop truck after a few seconds feel a little kick if that doesn’t happen stuck in 3/4 gear shut truck off wait few seconds and start usually ok again. If you down shift manually ok as long as you get into 1st before stop. If not it kicks . I WANT A NEW TRANSMISSION. Now I want a new truck it just hit 80,000 IDK IF ILL BUY CHEVY CAUSE THEY STILL HAVE THE PROBLEM AND REFUSE TO RECALL . Oh I’ve changed the fluid and filter 3 times now. And yes used mobile 1 not ac/delco cause it’s not meeting the requirements that mobile is did use ac/delco filter
