P0243 "The PCM has determined that a malfunction exists in the electrical circuit for wastegate solenoid 'A'"<p>Kind of MAF-gone-bad symptoms but not near as bad. Car "hiccups" every now and then, maybe once every 3-4 days. Car does not stall, but acts like it wants to for just a second and then recovers.<p>Should I check wiring, or have I broken something?<p><br>I ASSUmed the hiccuping was due to the dealer powerwashing the engine bay. I had to change the plugs after that. The wires were rusted where they connect to the plugs on the inside so I changed the wires and cap and rotor yesterday (CEL has been on for 2 weeks). No hiccuping yet, but like I said, it's every 3-4 days.
