+18 2004 Acura Mdx Check Engine Light And Vtm 4 References. Both the check engine light and the vtm 4 lights are on and i was just wondering if anyone can tell me what might be the problems that i have to deal with. Web the vtm4 light refers to the variable torque management 4wd system and could be triggered by many different errors aqlong with the check engine warning.
Rough idle was due to a bad egr, also covered. If i turn the car off then back on, vtm 4 stays off bit check engine stays on. Dealer says valve adjust scan comes up all cylinders misfiring even after ngk uridiums installed.
