I was following this thread for a while because I have a similar problem. My
problem is car starts fine when it is cold(hasn't been started for a while),
but if I try to start it after running for a while it starts very hard!!!  I
am also not reaching full boost any more(1.4 on display). I just checked my
error code and it came out 2112. Has anyone dealt with this error before????
