I keep getting intermittant Check Engine light on my '99 3.2 v6. It seems to happen more frequently during hot/humid weather. Stays on between one to three days of normal driving. Then off for several days to a week, then repeats. Happens a lot less frequent in cooler/cold weather.
I pulled the codes and came up with:
P0108 Manifold Absolute Pressure/Barometric Pressure Circuit High Input
P0121 Throttle Position Sensor/Switch A Circuit Range/Performance Problem.
I did a quick search on these codes and found no useful information. Air filter is clean, engine runs good. Any help or suggestions would be appreciated.

Thanks,
Dave
