I noticed when i had my stock exhaust that my car would back fire when slowing but now that i have another exhaust (louder than stock) i notice it more often. Does the car need a tune?? I get the oil changed every 5,000kms and every 10,000 i have a tune done

It's actually not a bad thing - I've been told it's a sign that everything is running efficiently and you have plenty of oxygen passing through to the exhaust after combustion.

Mine always rumbles and pops when slowing - It's nice :D. I've also noticed the car is more prone to do it when running on BP ultimate which tells me it's burning cleaner than other fuels.

My sportivo has never backfired. Don't know what you are talking about ?.

We used to make our old Holdens backfire. Find a large hill and give it some going down at about halfway turn the ignition off and back on.

A huge explosion :yahoo: and if you are unlucky your exhaust falls off. :clap:

I don't think most of the people posting in this thread know what a backfire is... the exhaust popping is nothing like backfiring.

Rumbles and pops - just that....

Backfire - backfire: loud noise and bang.... maybe some flamage if you are lucky...

I got a few rumbles and pops, but no backfire......notice them more with the CES but maybe cause it's a little louder, but certainly noticed it with the stocko exhaust...

True :rolleyes: my bad, I'm reffering to crackle and pop, not back-fire which is actually unburnt fuel flowing through the engine and then igniting when it hits the hot exhaust and giving out a sound that's the equivalent of a shotgun.

So Nickich are you getting just crackle and pop or actual backfiring? because the later is bad.

Its a series of pops. But the pops are pretty intense, to the point were you can feel them vibrate the seat

Is anyone experiencing this? :ph34r:

In my case sometimes certain pops (Particularly between slow shifts in stop start traffic) can be felt quite strongly. But if you feel it's a concern, just for your peace of mind have it checked at the next service.

But before you do, switch fuel for a week or two and see if this makes a difference for you.

my car makes that rumble and popping noise when you use a bit of compression to slow the car down ie 3rd to second. i love that noise ! yah i run 98 octane too.

never had it do the backfiring before tho. lol backfiring sounds cool like a rally car. :)

      Android auto

      OK. Does any of Toyota's advertising material mention Android Auto? If so then kick up a stink, with Toyota management, about misrepresentation and false advertising, reminding them of the hefty fines. Herb

      1999 Camry Driver's door locking hatch issue

      It's possible that it could be something fouling or dirt build up, dry, or a broken mechanism, so have a look and give the mechanism some lubrication, most likely though, it'll be the actuator. I found one for a good price on Ebay, $25 delivered: Front Door Lock Actuator Right Side For Toyota Camry 1997-2001 | eBay

      Query about the correct rotors for 2006 ACV40 Camry.

      Hi, I'm looking at a set of front rotors for an ACV40 2006, 2.4L Camry. I got a good price on some RDA's at Sparesbox. However both RDA8112 and RDA7686 show as for my car and I'm wondering what the difference is and if there were changes to the rotors during the model production. So does anyone know which rotor is the correct one? Many thanks in advance.

      Android auto

      It's a simple solution though? Already laying down 60k for a RAV4, so what's another 1k on a phone to make everything work seamlessly? 👍

      Your solution is akin to suggesting that switching to a different car manufacturer would resolve the issue. However, not everyone shares the same enthusiasm for using an iPhone as you do.

      Turboed Corolla Overbuilt?

      that engine will be fine, the rods are the main thing to be concerned about. The 2860 is a decent turbo for the 1zz but in this day and age I'd go for a G25-550. The injectors might be on the small side, we run DW1000's. You need a full length injector, the shorter injectors with adaptors like ID1050x dont fit the 1zz head. You don't need an aftermarket intake manifold, if you do go down that path, avoid the CNC innovations unit, it's garbage. Do the boost control with a MAC valve and control it with the aftermarket ECU of your choice, I use Link stuff on most of my builds with the G4x Storm as the minimum. I also wire a fuel pressure sensor and oil pressure sensor to the ECU in my installs. Use a decent intercooler, the better cores (ARE, PWR, Garrett, Vibrant, Plazmaman, Hypertune) work a lot better than the chinese stuff like Aeroflow. a 450x250-300 fits fairly well with custom end tanks to route the cooler pipes through next to the radiator Don't forget about the clutch and gearbox. These days I like the Uniclutch twinplate, Above 300whp you'll want to think about upgrading the 3rd and 4th gears in the box also with the SSC (Hollinger) gear set and install an LSD of your choice. If you're going to give it a hard time, you'll also want an oil cooler. I like the HKS thermostat type sandwich plates and setrab or mocal oil coolers with -10 speedflow fittings/lines (Chinese AN fittings neck down to a lot smaller internal diameter in their bends, not great for flow) You'll also want to think about brakes, Celica or Sportivo front calipers will bolt on with sportivo discs as a starting point. To have somewhere like Tunehouse do the work you'll want to budget somewhere between 20-40K

      Camry Touring 2010 Fuel consumption 15.2L/100km. Normal?

      I did the mathematics myself regarding costs vs benefits for fuel injector cleaner. I have changed from 91ULP to 95PULP and 98PULP. Price difference can be about 13 -20 cents. Compared to 91ULP, Premium quality fuel should have a better quality additive package designed to have superior engine cleaning capabilities so the engine can perform at their best.

      "Fuel injector cleaner is a waste of money" Only if you by the cheap crap if you use LiquMolly a German Product it does work and you won't waste your Money.
