Ok fellow Genvibers....I think I made a boo-boo. I replaced 3 engine mounts ( sides and front ) The rear mount ( firewall side ) I did NOT want to tackle, BUT it was SHOT and made a mistake of saving it for later. WELLLL 9 months and 10,000 miles later due to this COVID crap and just being busy I finally replaced that last mount. Engine vibration is much improved but I still have a bit of vibration that Im not happy with. I was expecting smoother. I know the 1ZZ isnt the smoothest engine and inherently has some vibration but it feels more than it should be. So the question....is it possible I may the ruined the new mounts driving with that one bad one for that long ? I did purchase OEM toyota mounts. I think I know the answer but need confirmation.
I also have a PO440, PO441, PO446 codes. Can that cause a rough idle ? I hoping its the codes causing that last bit of vibration. NOT the mounts. If I need to replace the other 3 so be it. Im not getting rid of this car Stupid me...I should have replaced the mounts all at one time, and i wouldnt be playing this guessing game. I know better....
