CODES on 1997 Mercedes-Benz C230


These are the codes that were found on my check engine light.I replaced the mass air flow 2 mo ago and I replace the EGR valve. It is still stalling out when idling. It is like it gets too hot and shuts down. I also noticed that if I turn my AC down the idle goes up.


P0 170 FUEL SYSEM TRIM MALFUNCTION BANK 1
P0 100 MASS OR VOLUME AIR FLOW CIRUCUIT MALFUNCTION
P0 400 REPLACED EGR DIDNT FIX THE PROBLEM
P1519 Adjustable Camshaft Timing Solenoid
I replaced the mass air flow sensor 2 months ago.
