Default limp mode NO CODES

Hey everyone been stuck with this problem for a while now . Car is a 02 gs300. I have searched all over but no results . Currently the car is in limp mode but NO CODES whatsoever. I'm stumped and don't know where to begin . Motor was just swapped with all seals replaced . Timing is on point motor idles perfect . Anyone ever go into limp mode and have no codes . This is the first for me. Some suggestions please .

A little more detail please....

You say the motor was swapped........swapped with what? Another GE engine on aristo? Have you checked the wiring to the MAF and the MAF itself?
Tell us what you have done so far.......

Swapped with another ge. Had some abs codes . Replaced unit . All and codes gone . Checked maf wires all is good. Checked tps checked throttle motor . Had extra throttle assembly. Swapped whole throttle body . Cleaned throttle body . Run scanner with no luck. Looking at live data everything seems normal . Going to take off midpipe and try revving . Myabe clogged???

Well took off midpipe and revved pass 3000 rpms up to 6000 without problems. Seems like it's the midpipe. Will try anotheridpipe and get back with results . Before could not rev past 2500 to 3000 rpms . Wish me luck😃
