Hi i need help. Last night i changed/replaced the LIM with all gaskets (Felpro MS98003T) due to a coolant leak on LIM. Today i just finished up reinstalling everything and replaced all vacuum hoses. Me and my dad tripple check everything to make sure there's nothing leaking or disconnected. When i tried to started at first, it turned on but the RPM's started to go high and wanted to go past 4k. I turned it off, tried it again and same thing. I plugged in my scanner and received code P0101 about MAF or VAF malfunction. I unplugged the MAF double checked it and nothing seems broken or out of place. I remember last night i cleaned it with MAF cleaner and left it dry overnight. I plugged MAF back in and tried to crank it up but now it doesn't start and it coughs pretty rough. My dad mentioned that i have no pressure on the fuel rails, so he put more air in and tried to start it but same issue. I did the suck test and holds vacuum with no problem and is not leaking. What could be causing the issue? sorry for long post. **edit** i replaced fuel filter a few weeks ago and Seafoam it 2 days ago.
 
Today, i plugged in my scanner and it gave me P0101 and p0102. Still having problems when car turns on, the idle goes high hitting the 4k rpm mark like if i'm holding the gas pedal all the way to the floor.
