UK Car Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.Backfiring through the intake in most cases indicates a valve timing concern. I would have your mechanic check the valve timing as well as run a engine compression test to be sure the cams are properly aligned.
Saman, I would go ahead and have him run a compression test to at least rule it out.
