So its mid winter here in Toronto, car is acting up again.
1. Still having misfire problems after hot restart.
2. Car stalls in traffic as if its starved for fuel and will have to restart to get going, (wont shift up and and holds at certain rpm then shifts really hard from 2nd to 3rd, this shifting problem happenings rarely)
3. As soon as i installed my winter tires, I'm hearing a howling sound from the right rear side that's on audible from 0-60 km/h then goes away after driving for 10- 15 mins
4. I've changed the whole ignition system minus the coil and ezl, fuel filter is about a year old. I remember the p.o telling me his mechanic changed the fuel pump relay when it wasn't starting, was thinking to start there ?
also how can i do a smoke test to find vacuum leaks
