help with some error codes.

[tim_pato]

07 kj diesel. I've had a look through the stickys but got lost. can someone please tell me where in the stickys i can find the following.
p0100 maf signal too low
then this fault showed but no code.
tps/apps high
I'm running yetis egr delete tune (or so i thought)
but it's showing 'excessive egr flow detected: deviation above limit'
the main issue i have at the moment is it's missing at idle and at cruising pace on the highway, the same thing it does when it gets air in the fuel. I'm running a carter in tank pump, all rubber lines and hose clamps and upgraded filter head. would any of the above issues be causing it? or is it possible it's sucking air at the pump?

Well lots of things it could be. I have no idea what a Yeti
tune is, so I can't comment on that. I would start by insuring you have viable seals on the fuel filter (is it tight), then I would bleed the fuel head to get any trapped air out. Road test then. Re the MAF that is easy to clean, just pull it out of the air box neck and give it a squirt of MAF sensor cleaner. MAF is only read on engine start BTW. Re the missing at idle and on the highway, if the steps above have not cleared it up, i would suspect an intake pressure loss due to EGR legacy connections or a new leak. You will need to explain what you have done to EGR plumbing to help understand possible next steps. If EGR is physically blocked at the exhaust manifold you could still have a boost loss due to a leak elsewhere. If you were running a GDE tune I could help further because i know exactly how that works.

If it's the free tune on lost jeeps I think that tune is to delete the error code if you have removed the EGR and FCV.
You have to physically remove those items to gain any benefit.
The tune does not turn them off so you may actually have a fault with the egr valve if it is not removed????
