Hello fellow prius drivers, I've noticed something that does not feel normal to me: Sometimes when the car is warmed up and ICE re-starts there is vibration in the cabin, I can feel it through the seat and steering wheel. I have also noticed strange popping sound from exhaust while idling (no necessarily when vibration occurs). The engine seems louder at acceleration (it was not like that when I bought the car). There's a short video: Could this be misfire ? Background about car: EU model, 142000km, second owner, no codes, recently changed spark plugs (DIY) to battle this problem - did not help. It is winter here, so temps are around 0C. Mileage is around 6.5-7L/100km mostly city driving, short distances. Appreciate all the help I can get.
Ok, get the codes read. If there a a misfire you should have misfore codes stored. Oil level ok? Rest of fluids ok? When changed sparkplugs? Cleaned throttlebody? All those things can make your car idle bad.
Do you take it for a long trip sometimes? Sometimes it will help to drive a long distance at high speed to get al the fog out of the engine and oil. Car will may run smoother after that.
Every other weekend I go on a 80km round trip at around 100km/h. I guess I will drive it as is until there are some codes
I just went through the bills and I see that I ordered DENSO VK16 spark plugs (as opposed to SK16R11). VK16 seem to have 1.1mm gap (which as far as I know is what TOYOTA recommends). Is there any chance my issues are related to the spark plugs that I've just put in ?
Check engine/transaxle mounts, and look for an exhaust leak? Is the exhaust the normal color, odor and density? By all means, double check the spark plugs.
Don't know, but according to a Denso Toyota cross reference I found, they are an equivalent. TOYOTA Cross Reference | Denso Spark Plugs| Denso Global FWIW.
