Five times now, feels like emergancy brake is on and car revs to around 2k rpm and feels restrained from moving, then kicks in with a slight jolt as if to in gear or shift to move and runs ok once moving. Idle additionally is also very rough. Just replace spark plugs and valve cover, have run red line injector cleaner no differance in idle. A friend questiions my coils but not sure if it is the roughness. Just replaced radiator that blew the hose plastic fiting. No internal lights or codes went on at all. Thanks for the help as what may be the two issues, Dennis Keno OR 541-281-7418
