a to b car, stock everything. 197k. a2 engine. car has given me little to no issues in the 45k~ ive owned it. car randomly shut off on my while I was making a left turn today. Put it back into park after stop and started right up, but idle was low/sputtering. Once the foot is on the gas.... the car accelerates normally/drives fine.

an hour later... go to work.... 50 miles highway and the car was normal from start to finish, no sputtering, no stalling at traffic lights or stop signs. no sign of anything.

no cel.

did a major tuneup/transmission swap in july of 14 45k~ miles ago, in dec 14 crank sensor harness went bad, thats literally the only issues I have had with the car since all the major work in july 14

I'm thinking changing spark plugs as it is cheap, easy, and probably should have been done by now, but I cant help but think there is a sensor that may be going bad or something.

what you guys think?
