GAS SERVICE

gday robert.
have you changed where you fill up on gas lately.i certainly know if i get dodgy gas backfires wont climb a hillšqUC3<BuIL

i have had this happen as well watch out for dodgey gas dudes it took me 4 goes to get it right ie 1 did new line placement (too long ) the other tuned it down a fraction and another said timing module (crap).
And finally after 3 new air filter boxes after they all blew up i just replaced the converter.
went well after that .

The guys here (Terang) are excellent, I could ask if you like for a recommended do-er in town ifn ya wantLaterally Literal
Seriously Serial

Just a suggestion but check the water flow through the converter is good as poor flow in cold conditions will do exactly that, and also on the converter there should be a drain plug. Over time condensation can build up inside around the diaphram and cause improper operation of such. Drain it.(turn the gas tank off for safety first)
It's a good place to start and at least you can svae time for a gas guy if you have already done that.
Good luck i hope it's simple and not a drama.

thanks guys for all the replys i will take all that information with me

Hi Robert,

I might be a little late with this reply, but I would suspect a mixture that is too lean caused by an air leak somewhere on the intake side of the engine. I had a similar problem with my 4Runner and the backfire blew the gas converter in half! Best bet is to take it to a qualified gas mechanic before it becomes too costly. Drive it on petrol for now.
