This morning when i started my vx V6 to go to work it backfired as soon as the engine turned over, and everytime i have started it since today it backfires, was wondering if anyone has some ideas as to what it might be.
There is no loss of power while driving and engine idles the same as it always has, it is petrol and the plugs and leads were replaced 10,000km ago. it only seems to happen when i start the car, and happened once when i turned the car off. thanks heaps
incorrect timing, sticky exhaust valve, leak in exhaust, problem with coil pack or leads, (look at motor running in the dark, watch for stray electrical sparks). I'm sure other forum members will come up with more probabilities. Although seeing it happened when you turned the car off, exhaust leak and spark problems seem likely. Hope this helps
