WERID NOISE FROM THE STIVO??

[mr_rice]

Hey all,

Got a problem thats been ****ting me for about a month now...

I've looked all over for anyone else with the same problem but cant find anything...

anyways, when im in low gear lets say 4th... and have the aircon on.... and basically get too lazy to shift to 2nd (to keep the revs up) and keep driving i get a very noisy rattle from i'd suspect the ac pump/condenser?

It happens at around 2000rpms - 2700rpms. (even in 1st)

I know its the a/c cos it only happens when i have the a/c on...

Please help me out cos i really just wanna smash the car into a tree right now..

Cheers guys..

Sounds like it is labouring/pinging - which is not great news for your engine, spark plugs or performance overall.

The simple answer here is to stop being dang lazy and drop a gear!!

(A more technical answer should follow from someone more knwoedgeable, like SuperDave!)

i have a similar issue at the moment in my corolla,do me a favour and put it in 6th and sit at 2000rpm and put the accelerator pedal to the floor and tell me if it is noiser than in the other gears.let me know!

[SuperDave]

Sounds like either pinging/detonation or the accessory belt tensioner rattle. But at that high a revs I'm not too sure. If it is only occuring with the AC on it could be the bearing in the AC pulley is gone.

Tensioner or pulley?

[123R-Prozak]

My bad, pulley lol

[mr_rice]

Prozak.

Where did u get it from and who fixed it?

Are u in Syd btw?

And I've tried not being so lazy lately so the noise isn't that bad...

Are the engine mounts common to go cos in 5th when I let go of the accelerator and press it again I get a slight knock....

[123R-Prozak]

Yes I'm in syd, my parts supplier, cause I'm in the mechanic industry it was that price for me, was a yr ago abouts maybe, bit less, I posted pics previously..

I think sd figured out u can drop the frame and get to it rather that lowering the mounts? Can't remember

I did it
