Vehicle is currently having these problems; bank 1 misfire, EVAP system leak (P0442), bank 1 running rich (P0172), MAP sensor voltage too high (P0108) and random misfire (P0300).
Misfiring at all speeds, hesitates, idles poorly, when put into gear the car dies.
Freeze frame data for misfire is:
fuel system 2
STFT .78
LTFT -25.78
MAP 24.51
Have replaced fuel filter, fuel pump, fuel pressure is fine, plugs, coil spark plug wires, MAP, and TPS.

evap system leak. CHECK your gas gap make sure it is sealing properly (p0442) is also known as the gas cap code
CHECK your coil pack for cracks. I had a misfire on cyl 1 (P0301) just yesterday looked at the coil pack and it was cracked 30$ from the wreckers for a whole setup incl. delco plugs 30 min to replace and the problem was fixed (cyl 1 plug was fowled)
Good luck

its a certain part in the intake manifold that needs to be replaced or adjusted.
not sure wat its called on ur car.
but its either called the
EGR valve.
or
idle air control valve.
it is adjust with a flat head and requires no money to fix.
usually located under the throttle body.
if you havent done this before its impossible to know what im talking about.
a mechanic will do this for about 100 bucks i think. even though its 1 minutes worth of work.
Good luck. my mechanic showed me where mine was. i hope urs does too .
