Slight Hesitation after Knock Sensor?
So my 1997 Outback Legacy Wagon, 5 speed manual with 118k miles was throwing a knock sensor code, which the dealer changed and cleared the code. They had the agreement with the previous owner, and did it no charge to me.
Prior to that, I drove the car around about 85 miles with the CEL on, and the car drove fine.
After the dealer changed the knock sensor and cleared the CEL I am getting a slight hesitation in the 900-1600rpm range.
It is rather weird, as it doesn't happen all the time. It happens in gear 1, 2, and 3 only.
Basically say I am driving at 45 mph, then coming up to a light, downshift to second, slow down, and release the clutch (THIS IS WHEN IT HAPPENS), if the RPM at this time is in the 900-1600 range, there is a hesitation, shaking of the car (best I can describe it) as it is going forward.
THen it becomes fine.
It also does it, from a stop light, 0mph, in 1st gear, release the clutch, and then it does a bog.
It doesn't do it all the time, but intermittently.
I also thought maybe I wasn't putting enough gas from a stop, but I am. If I rev to 1500rpm, it isn't doing it in 1st gear.
It isn't a big problem, but can be annoying sometimes.
I am doing a full
In 2 weeks. I am wondering if there is anything I need to look at , or if this is a common problem.
