Acceleration, or not so much...

[BobLabla]

Alrighty then.... So back for some more brain picking! I've since done my overhead and that darn mandate ousted! I am still having an issue where about halfway through the day my engine starts to run like shi#t. It gets very stumbly and starts running hotter than normal, you can feel the heat radiating from the doghouse, and feel a stumble at idle as well as a huge lack of power. Still boosting in the top end, but just doesn't have a crisp acceleration and a very lazy start up even empty. Could my shitty injectors be getting worse with more use and heat throughout the day? Or fuel solenoids affected by heat? Bout to tear some more hair out.....
