Hey guys I am having a serious headache with this car please please help.

Long story short, clutch was changed car was running fine before it went it.

Picked car and it was idling weird. Checked all wiring and noticed that two wires from fuel tank breather valve were shorting. Fixed those but was still getting half power. Replaced breather valve and it stopped the erratic half power.

Anyway I keep getting the following error codes

P2102
P1638
P1639

AND

P2188

I have checked for vacuum leaks and cant find any.

I am hearing the following info, could be the throttle body got shorted, could also be the MAP sensor, finally could also be the battery.

Fuel consumption has gone through the roof.

Any help will be much appreciated

No gunk in throttle body, weather is very hot here (think texas) no ice.
