Hello all,

I have a question about my AU3 Falcon. It has backfired back through the air box five times in day, to me this is not normal, and shouldn’t be happening.

I have never replaced the plugs or the leads, and it only has 171,000km on the clock, 100,000km of which, I have put on the car myself.

It is a 6 cylinder, dedicated Ford LPG if that makes any difference.

ANY help or advice would be greatly appreciated in regards how to fix/stop this backfiring, and also, what is/could be causing it to backfire.

Except for the XR6T intake mouth and the cat back exhaust, it is a completely standard car.

Thanks in advance,

Peter

chnage the plugs and leads!

being lpg it is more sensative teh ignition problems

how did you go with plugs and leads id say thats the problem

Looks like i'm not the only one having backfire issues. Fun isn't it As the boys have said, it is most likely the Leads and to a lesser extent, the plugs. I recently changed my plugs to platinums, but haven't done the leads yet, and it still has the occassional backfire. I recently cracked my airbox lid in a couple of places so probably best to change your leads now before you start to see damage as I have.
Try and get your hands on a set of Ice leads, from what I have read, they are the most recommended and worth the extra $$ as I have learnt the hard way I hopefully will be getting a set Very Soon, so will let you know if there is any improvement. Also get a set of spring clips from Ebay to reduce the build up of pressure in the airbox if it does go "BANG"
