Car was running like shit. Kinda chasing the gremlin. I replaced the fuel pressure sensor, no joy. Replaced the MAP sensor and cleaned the MAF sensor. The high pressure fuel pump was replaced about 18 months ago. Car seems to be idling ok now but the RPM did dip to around 600 rpm for a moment. Gotta test drive. If I still have issues, do y'all have any ideas whats next?
