Hi, i got a Volvo s40 t5 awd MT, and sometimes when the engine is warm, it prefires at low rpm (Max 1500), and sometimes when i shifts low gears it feels like. It has 245k km at the clock. It was a lot worse before, but after changing the spark plugs, the problem almost disappeared. Then it suddenly started prefiring again, and then I cleaned the throttle body, and the problem disappeared for a while, now it’s pretty “stable” but still get prefiring sometimes at low rpm and with some load (uphill)
