got a 96 ps with 0605 and 1668 codes and it runs ruff if u mash th pedal = more than a quarter of they way down other wise it runs fine idles good and while its cold it runs fine it just happens when it warms up idk
0605 is Internal Control Module ROM Error and 1668 is PCM - IDM Diagnostic Communication Error. I guess it could be a PCM problem, especially with 0605 (can you clear the codes and rerun the diagnostics?), but ... Do you have problems restarting it when warm? You could have Injection Pressure Regulator (IPR) valve o-rings on their way out or even bad injector o-rings (does it use any oil?). The warm oil will more readily bypass the o-rings than cold, thicker oil. Cheers!
