some one unhooked cooling plate fuel lines , does ecm have alot to do with fueling on a e7-400 mack 1999, never had a cooling plate unhook be fore computor  may get hot .

on this e7-400 1999 somebody unhooked cooling plate behind ecm, how much control on fueling does ecm have on this mack ,and cooling plate should be hooked up right

When you say “air to air” is that just the CAC? If so you have only checked half of the charge air system. Turbo could be getting worn, boost leaks at turbo/before CAC, or boost leaks after CAC/at intake manifold. 

checked all that seams ok

code 238  fmi 4 plus code pid 100 fmi 4  and thats all codes, light does not come on only for a second at start up thanks

 no air leaks  turbo is tight power is light problem started slow  than never got worse thanks

fuel pressure 90 psi

thanks all
