I am hoping I can get some advice on my 2008 Suzuki forenza. Started throwing the engine code throttle position sensor, throttle control system a little over a year ago. Replaced throttle pedal and throttle body with new parts. Still throwing same code. Replaced engine control module and transmission control module with used as it is getting very hard to find new parts these days. Still throwing the same code. In the meantime while this is going on, random loss of power not when check engine light is on then my forenza "farts" a huge puff of white smoke. I thought "oh no another blown head gasket" but no, compression test done good compression did not act exactly like it did when I actually had a blown head gasket. No leaks that would indicated blown head gasket except the brand new valve cover gasket keep getting blown out in one spot. Engine is leaking oil at the valve cover. Burns and smoke comes out from under hood. Now with all this the car still runs pretty good and starts up everytime. Engine seems otherwise in great shape. Any one have any ideas? My mechanic cannot figure it out.
