p1627 code

[Raor.90]

I run a daewoo lanos 2001 having rare problem.it starts fine but once you try to acelerate it has no power.I already replaced the ecm,oxygen sensor,colant sensor,wire set,spark plugs...The only thing I did before was to replace the exhaust manifold with an exhaust header and down pipe.It ran smoth for a week and started having the problem.the only code it has its p1627 that states the ecm has problems converting from analog to digital...and only resolution to the problem its that that the ecm its damaged and needs to be replace.wich I already did.If anyone knows anything of a similar problem please let me know.it runs without any power.it barely wants to start moving...my e mail its Raor.90@hotmail.com...I'll apreciate any help..

didn't someone have a similar problem with a restricted exhaust or clogged catalytic converter?

Are all the indicators working correctly? Fuel, temp, speedo, etc?
