any news on this problem ? did you solve it ?

it sounds really close to my problem here

mine is solved already,,

it was the fuel tank breather valve going out,,

my car never stalled under any condition,,

your problem sounds like a dirty throttle body or an intake vacuum leak somewhere after MAF toward the engine,, check the air intake pipes and manifold gasket,,

there is a slight possibility that the excess oil has reached areas further than the throttle body where they may easily reduces the air flow to the engine,,

if possible,, take off and clean throttle body, MAF, air box, intake pipes and manifold,,

keep us posted,,

i tapped the issue for a clear view:

my local stealer still can't do anything with it :(

Loren,

The 2000 996 is e - gas so there is no idle valve.. Is that correct?

Correct.

My guess is he still has a dirty throttle - likely behind the butterfly.

If not I guess it could be an intermittent throttle positioner - which would mean a new throttle body.

i have removed the throttle body completely that day to clean it inside out,,

is there a way to test the positioner?

how much is the TB?

an update,,

i took the car to the dealer,,

they found no codes,,

cleaned the MAF,,

reflash the ECU,,

checked all possible causes,,

chraged me $200,,

later at the same night the car was out,, it happened again and the RPM dropped to 200 revs and back up again,,

i am out of ideas,, please, please, help!

:@

sorry i for the tons of questions,,

I needed help since my local dealer doesn't seem to be helpful on this,,

Thanks.

Could be - the pending codes would say if you have an air leak and the MAF test would say if your MAF is bad.

Is there anything else can cause this problem?

Yes, you could have pending codes and if your scan tool allows it check to see the MAF voltage. It should be stable at idle and increase with RPM.

some said that my AOS is going out,, what do you think?

i tried once to remove the oil filler cap while the car running,, didn't stall but it idled roughly,, is that something??

what is the ideal idle rpm? mine idles @ around 700,,

have you checked for fault codes? You may have an air leak or a bad MAF.

there is no CEL,, do i still have to check the codes?

i have once unplugged the MAF and the symptom popped up again,, i guess this eliminates the MAF,, and the leak,, right?

at traffic lights, the rpm goes down to 200 rev for a second or two then the idle goes back up to normal.

i have cleaned throttle body and MAF but didn't fix it.

my car is MY00.

What is this?

is there anyway to check trans/diff oil level?

if not, what are the symptoms and signs of low trans/diff oil level?

last night, i heard a recurring rubbing sound which was proportionate to engine revs,,

this morning, i took a closer look at it and found that the lowest engine pulley on the left side is running unbalanced and rubbing to the belt making that sound,,

what is that pulley?

how to fix that?

is it serious?

thanks,

KJ

what is the most recommended brake pads brand/model for 996 C2 street car?

what are other parts should i consider in brake pads replacement?

do 2000 996 C2s have brake pad wear sensors?

Welcome to the forums.

The maintenance schedules are posted on this site at http://www.renntech.org/forums/index.php?app=maint&do=maint_menu_car

The only known free service manual available is at http://cannell.co.uk/Manuals.htm , and is for the 1999 model year. however your car should be virtually identical.

i have been to the services schedule section and couldn't figure out when to replace transmission and differential oil,, when to replace them? any parts required?

my 2000 C2 will turn 60,000 km where it needs a scheduled major service,, anyone knows what are the jobs done and parts replaced in major services?

just wonder where i can have a copy (free if possible) of the service/repair manual for 996 Carrera.

hi everyone,

i am new to this forum. i want your advise on a killer deal i am having on a 2000 Carrera. the car has only made 60,000 KM (40,000 miles). i took the car for the last weekend to decide and noted the followings:

1- whining sound from the back end @ 70-80 km/h (45-50 miles/h) the whining then goes away

2- at full stop, the idle is not perfect and the car slightly vibrates

3- at full stop, some front end noise when swinging the steering wheel

beside the above, the car feels perfect.

what do you think of these notes? are they critical? what are the possible causes and solutions?

thanks in advance,,

KJ

the whining sound at those speeds might just be the rear spoiler going up automatically

the car has a fixed spoiler,,

when i got off the car and checked the rear tires, i found them of different patterns and sizes; can this be the problem?

Chances are someone changed out the radio and did not update the serial number information.

Did you try getting the serial number using the method in the FAQ?

i got the SN from the display by holding TP until 'BECKER 1' shows up then i used the right dial.

You can try the suggested varying the number I gave you by one or two each of the first code and see if you can find it.

Just takes patience because of the time out after every three trys.

2451 BINGO!

thanks a lot :)

If you have not already read this FAQ - please do so...

Lost Radio Code - FAQ, PLEASE READ THIS FIRST
