Idling problem Sign up here! Search this forum this category all forums for All words Any words Whole Phrase (search options) Auto Repair Home>> Automotive Repair>> Car Troubleshooting chipvan New User Aug 1, 2007, 4:41 PM Post #1 of 4 (1395 views) Idling problem Sign In I have a 94 Mercury Topaz. The car is idling so fast that I have difficulty coming to a stop. It is idling at between 2000 and 3000 RPM. It used to idle at just under 1000 RPM before a mechanic replace one of the vacuum hoses. It is maintaining this idling speed and will not drop back down to around 1000 RPM. If I press the accelerator it get worst without dropping back. Could the problem be some type of sensor problem?
