Now everything it out back together the car runs but the PROBLEM OF THE LIMP MODE IS STILL THERE !! I can't even rev pass 2000rpm, even when parked! Something must be playing up and I'm thinking it's the AIR FLOW METER. Ever since I changed the Pod Filter the problem started, but the thing is I changed it back to normal but it's still limping, I can't even hit 60Kms on the road :0

When my MAF was bad the car wouldn't rev past 3000rpm, it made my car run rich and when I changed the MAF it did not run right as the plugs were fouled. Thoguht I would share that. Pull the MAF sensor plug while the car is running, should make a difference on AFR's, idle speed etc.

Haha dam but did the problem happen as soon as you start the car up ?? And I'm thinking of buying a New AFM and replacing it. I've tried spraying it down with electrical and contact cleaner but nope seems the same when i take it for a drive. 

1.It would drive Fine past 60kms till it gets a little warmer or after 3mins and then BAM it just won't let me rev past 2000rpm and i'll be limping the car home on 40kms LOL ! 

2.Then turn off the car, and turn back my ignition on and i got my A/T light flashing !  after about 10mins, I start the car up and its back to Normal
 

Then repeat 1.

Weird problem, it could be the AFM because it previously had a BLITZ POD filter and i swapped it for a bigger K&N POD filter. After I changed it that night i went out for a quick drive and climbed to 100Kms safely while going hard and after a RED light ( car was idling fine ), when i accelerated it wouldn't let my Rev go past 2000RPM, i thought at that moment my car just died on the spot !

 

After that went home changed New Spark Plugs and Coil Packs cause I thought that was the problem but NOPEE. Still happening ):

[Jonic]

So weird now my car won't start up, it's doing the same thing again LOL, I'm getting a new AFM and see what happens

[admS15]

Unplug the afm and try starting it again

[Jonic]

I Unplug the AFM and tried starting it up but NOPE, its cranking and it kicks in but then cuts out immediately LOL what now ? 

[Jonic]

So I got a New AFM and the car finally starts but the problem is still there, SO WEIRD :S

[Jonic]

So I got a scanner and got what says : A/T CVT Fault & ABS/VDC Fault, I believe it's the AT because my transmission is jerky and pretty clunking and it puts the car in Limp mode so it doesn't damage the car from what I heard. Any thoughts ??

[Jonic]

have a look

[89CAL]

Cant you go into where it says fault and see what the fault is?

[Jonic]

I stupidly erased it before I even had a read. Now it's gone so gonna wait for the problem to occur again zz

[Jonic]

Car starts up now, sounds perfectly fine but at occasions after 10mins of driving when on idle or when driving the rpm drops slightly and starts to shudder like the car is about to die and the rpm goes back to normal sitting at 1000rpm. any thoughts ??
CHANGED : Spark plugs, Coils, New AFM, Fuel Filter. No visible vacuum leak, cooler hose or tight with clamps. I'm lost

Try swapping out a known good CAS. Get fuel pressure test. 

[Jonic]

Took it to the mechanics and there clueless, went to 3 different places. They got the same code but are clueless why it's having trouble starting. Have to push the pedal in every morning start up. Am randomly car struggles with revs then shuts down when at a red light. Car idles perfectly at 1000 when warmed up no hesitation or shaking only until when it's warm up it will randomly just drop revs like it's about to die on me

[Jonic]

Went mechanic today, turns out my transmission hose was bent too much and stopped the fluid from going through so he replaced it, and did a clean on the idler valve. Car has been running beautifully, no stall or any random vibration, that's probably why the A/T fault was on the OBD2 scanner. Brilliant.

[Jonic]

Hopefully tomorrow morning I can start my car without having to press my gas pedal in. Let you guys know tomorrow

[Girorostar]

Hi Jonic. Which transmission hose if I may ask? 

Thanks,

[Jonic]

OBD 2 scan said it was the COOLANT TEMP SENSOR, I pulled it out and there you go it's broken in half. There's my problem after spending money and time on either irrelevant stuff

[Anfanee]

Do you really need 3 threads for this?

[Jonic]

lol desperate times when you can't get your car started. It had too many different problems that I made different threads for different response lol
