For several months, I have had an intermittent hard miss at idle
in my 2006 TL- worse when in gear, (drive or reverse) completely gone when some throttle given. Zero codes on OBD scanner, can fish up what came up with a Solus, but none appeared remotely related. Recently, the car ran rough when accelerating on one trip, and the VSA light came on- and havent had that type of issue lately but VSA stayed on.
Timing belt was done 20k miles ago, valve adjustment about 10k ago- but no problems at all until about 3-4K miles ago.
Engine mounts were done w/timing belt- and otherwise it runs fantastic.
I get 29mpg on long trips at 80mph, but the miss at idle- mostly in gear and at a stop- is driving me nuts.
I did replace the steering rack just before this happened, but drove it for a good 2 mo the with no issue. Im checked all elec. connections, dont see any falling off.
It is a hard miss-meaning almost like the engine is trying to cut off. I dont believe it is coil related, as I never have a misfire code. I will try some new ones if needed, but the lack of a code, intermittent nature, and lack of oil down in the spark plug hole makes me believe that isnt the case. Spark plugs were all new as of about 10k ago and I used NGK.
Many ideas are appreciated and I have no idea if the VSA is related.
