It seems that everytime i switch on the A/C, as the compressor kicks in the RPM Lowers down to as low as to 500rpm from a normal 900-1000rpm(A/C off). The problem worsens when the headlights and radio are ON altogether. And as u start to drive, it feels like the engine isn't up to it's optimum potential....another word is - it drags..Which makes me prefer to drive it with the window down most of the time. This is the part where i do not understand why the engine runs much more smoother with the A/C off?PLus the radio shuts down on it's own everytime the signal lever is in use. Even the power window goes crazy too sometimes as if there's an insufficient power supllied.Are all these symptoms normal for an e30 like mine?thanx in advance.appreciate it.</p></blockquote><p></p>
