Q: My forester recently threw a p0028 code. Replaced the intake solenoid and oil pressure switch but the idle is still rough.
Recently changed oil and filter. Checked the oil level. Engine almost stalls when stopping. No problems when maintaining speed or shifting.
My car has 80000 miles.
My car has a manual transmission.
If you used thicker oil than vehicle specified then this can cause problems with the intake variable valve lift system. If you used the wrong oi then change oil and filter again with the proper viscosity oil. If the correct oil was used then you will need the system diagnosed for solenoids and sensors for the variable valve lift system.
