The posted code is the only current code. Since clearing codes and disconnecting batteries I have not used truck but I do recall seeing p94 fuel pres code a while back. It starts good and runs smooth etc. Im leaning towards poor or weak injectors. Thanks for the info, cant wait to see what dealer has to say, will let you know. Wonderin if I should get my own dyno test done b4 seeing dealer?

I will have to take it to dealer. Would 60,000 km do in the orig injector cups? What should i notice if they are the culprit. If in fact the abs or traction control is derating what would be the change in horsepower? It feels like about 125 hp short in my mind. The dealer had a third party dyno test done during my last viait with 385 rear wheel hp being "their results". I just wanna make sure im headin down the right trail. One thing i do know is that dropping the air bags while travelling derates to the point where you cant push the wind. If this is derate ive got something else wrong.

The horsepower is 485. It has always started fine and other than poor pulling has ran fine. I do have the VIP screen and habe the fault codes. Proor to che3cking the screen I removed the bat cables, checked and replaced cab fuse 13 abs engine circuit protector f49 -abs, they were missing. Turned all back on and now have the yellow ATC on steady with no flashes. The active codes now are ABS mid 136, SID 89, FMI 9. I suspect I may have a problem with ABS or traction control. Will ths derate the engine, and how do I tell when the injector cups are done? I.m the second owner but think that warranty may cover.

New to this site. Have a 2008 mack with the mp8 engine. Seems low on power compared to my pld 1990 400. Have had local dealer do turbo update and try to diagnose lightning bolt indicator. They cannot find problem. Truck has 60000 km on it now and otherwise seems fine. Does anyone have any suggestions?
