EGR Blank causing limp mode

Hi ET and others
My comment around the MAF readings and EGR was that unless somehow the MAF triggers the EGR solenoid to open (and add exhaust pressure to the intake system, slowing down air flow) then I could not see EGR plates affecting MAF readings. From your note above, it seems the ECU looks at EGR solenoid position--not sure how that affects limp.

QUESTION FOR ALL:: Is there anyone who has "limp" cutting in, AND does NOT have an EGR plate???

On a direct injection, I would say there is plenty.... limp mode is just an over boost safety thingo. Other factors could bring on limp mode.
