Random misfire on Octavia 1.4 TSI CHPA 140ps mostly on cylinder 3 and 4, not Injectors, sparks, coils. What to do?
On hot ambient temperature misfires are more than in cold mornings. For example 2 days before i had 129 misfires on cylinder 4 for 1000 rpm on idle speed. On next day with same conditions i had no misfires. What can be the issue, any temperature sensor, trottle valve?

Random misfire on Octavia 1.4 TSI CHPA 140ps mostly on cylinder 3 and 4, not Injectors, sparks, coils. What to do?
Hello, i have a skoda octavia 1.4 tsi chpa 140 ps 2015 on 205 000km. First owner. The car had no critical issues for all mileage. Since February 2026 i have an issue with misfires on random cyliders. I check them with VCDS and OBD Eleven 3 on live data. Also total counter on cyliders is very different on cylinder 4 as: 1-26000; 2-27000; 3-30000 and 4-41000. For certain trips the car generates up to 50 misfires mostly on cylinder 3 and 4, very less on others but still exists. There were a fault codes as P0300 and P0304. I changed: 1) All 4 pcs. of injectors with new by Bosch. 2) Changed the coils from 1 to 4 and from 2 to 3 but no difference. 3) Sparks were also changed, no solution. There are no errors as P0300 and P0304 after injectors change. In the mornings, when air is cold 15 degrees misfires are less, than in hot wether as 30 degrees ambient temperature. In the mornings during catalyc heating there is no issue. When i turn on the AC the misfires gone and no misfires. Without AC misfires exist. Idle rpm are 719 rpm/min. No issue with fuel preasure, injectors sealings, fuel rail, sensors, air filter. I checked the vacuum PCSV with oil cap opening, no issue seen. On intake valves has less carbon on the valve tail. I didn`t do a hasenut cleaning. Has somebody same or simmilar issue? How was solved? Why AC reflects to the misfires? The reason to solve this issue that i feel every misfire of engine. The shakings are very anoying.

Hi i`m sharing a 19" Extreme rims with 225/35/19 on stock 1.5 G-tec. Front looks higher due the lifting for the wheels change minutes before the photo. After short ride front susspension goes low. I`m thinking to change tires to 225/40/19 to avoid damages due bad roads in my Country.

Yes, PCD is the same 5x112 and i have steprings from 66.6 to 57.1mm, my concerns are due 9J and ET35. According tyre calculator the wheels are 49mm out than stock one.
