Hey everybody I have a 2004 subaru wrx well it seems there's a sputtering/flickering sound coming from the what sounds like driverside front and only seem to hear it during acceleration. my idle is at 500rpm if that is right. I was thinking fuel injector but not sure seems like it's robbing some power from the car just recently repaired fuel pump to clear cel and felt like some power came back but it seems to be really effecting my lower rpms. help is appreciated. and i can smell from the driver front side under the hood burning coolant smell and smoke sometimes and usually when it's cold. all of which though makes that low rpm feel real shaky and powerless.
