Limp mode prostar 2011 not accelerating

[Rawze]

Start with an EGR tune-up, replace the EGR Delta-P sensor and clean out the tubes for it, replace the IMAP and exhaust gas pressure sensor. Those are good places to start if all that stuff is old.

Also don't rule out the possibility of the acelerator pedal.

Your first mistake was to take it to a stealershit!!!>..

It sounds like the stealershit or shop has taken you for a ride on it. They are guessing in the dark WITH YOUR MONEY!!!--- I WOULD NEVER HAVE LET THEM DO THIS!!! -- WASTE OF TIME AND MONEY!

Connect Insite and take it for a spin. Watch the Engine state parameter while it acts up. It will tell you what has it in a derate. -- if you don''t have insite,... -I FEEL SORRY FOR YOU! -- It is a must if you own a red engine.

Also watch the crank/cam position sync state (or whatever its called) and make sure it is not loosing sync. This will make it loose power too.
