Hello
Re: 2010 Altima 2.5S -- 110,000 miles
During long trips at highway speed 65-80 mph, then coming to a stop (in congested traffic -or at a stop light), every once in a while there is a shutter where is seems as though the engine may actually stall or die, but it never has died. It continues to go into an idle. Then as acceleration begins the engine seems to correct itself and the shuddering near stalling disappears. Then it may or may NOT have reoccurred on that trip. The engine temp and CVT temp do not seem to be an issue.
The CVT fluid and filter(s) were changed about 4 months ago. The paper cartridge and the mess filter both were changed, the old fluid was removed via a pump in the fill tube and all of the old fluid removed and replaced by a systematic fill suck and refill until the Nissan OE fluid ran green and clean. At the same time as the fluid and filter(s) replacement, a OEM trans-cooler kit was installed.
Anyone have a thought on the "Shudder" ? Could it be a "dirty" throttle body? Or what do you all think?
Thanks! RichardinKY
