Ok so my car has been throwing the lean code (DTC 55 and DTC 44)
I have....

-replaced fuel injectors to 26lb injectors
-replaced fuel pressure regulator
-replaced fuel pump

I have no idea what to do as of now! Any ideas?

Thank you.

 

lol replace the fuel filter

 

Are you running the 26# Accel injectors in your signature? They seem to cause a lot of problems, compared to other brands.

Have you checked your fuel pressure? Have you cleaned the MAF? Have you checked for a tear in the inlet elbow, or to see if the bottom edge of the elbow is not over the throttle body? What kind of HP is it making - 26# isn't much of an increase over stock.

 

oh sorry lol i just changed my fuel filter as well.

Yes, accel. 26lb injectors
I dont have a MAF in my year.
Have not checked fuel pressure and yet to be dynoed..
My elbow is tore and i dont know if its totally sealed. would that cause it to throw the code? I kind of have my intake system patched up ghetto right now

And thank you for the imput

 

I would get it on a scanner and see what the o2 sensors are reading and check the other sensors to see what else might be contributing. Could be a number of things.
speed density so maybe your map is faulty.
