Hmm I wish I could be more helpful. In my AP1, replacing the injectors is what cured this issue. I had all the same symptoms.

 

Watch these injectors that I used NOT be good lol this is driving me nuts.

 

I went thru 1 set of injectors which made the problem worse. The 2nd replacement set turned out to be OK.

 

Comp test was good as well. Might have to try a brand new set of injectors. Ugh.

 

Adjusting the TPS did nothing.

Anyone ever sent their injectors off to be cleaned and flow tested? i'm thinking this might be the answer since new OEM's are obnoxiously expensive.

 

Didn't you determine that sonically cleaning them wouldn't fix a spring or two? Hopefully it would but there's only one way to find out...
For the price of brand new OEM injectors you could take your pic of quality aftermarket higher flow ones but...you'll need to get tuned too.

 

I did and found one was performing a little less than the other three. But after cleaning it still hasn't solved my stall issue as well.

 

Do you have the same symptoms as me? Aka high positive fuel trims at idle?

 

im not sure if i have high positive fuel trims but your symptoms sound similar to mine. when i swapped my TPS to omnipower, and readjusting it to spec did help a bit. But then still stalls out.

 

Yeah you need to hook up an OBD reader and get measurements; otherwise you're just guessing what the problem is.
