Help!! Engine died while reversing :(

[Mojoe]

yah man... hopefully not serious otherwise $$$ gone... bad timing especially with 2 wedding dinners looming

 

only happened today... just hope it's not auto tranny...

[Unknown_G7]

Once I asked my mech to lower it to 700 - 800 but he said cannot. Maybe mine is an old car, not strong enough!

[BoneStock]

No lar Bro...don't say that lah

 

I used to drive old cars too....think because older cars got alot of "loose" parts in the engine compartment so rpm tune higher a bit will reduce the vibrations. But my previous car quite ok though, I drive until scrap still can maintain 800rpm all the way

 

For engine with 3 cylinders, usually the mech will also tune the rpm higher to reduce vibrations.

Do try checking you vacuum hoses like Vtecc mentioned, also check the idle control valve. My brick did this stunt where low speed braking or standing idle too long causes the engine to die, due to faulty idle control valve....

Hi there:

 

I believe that will be your auto tranny's problem.

 

When you're in 'R' with brake applied, the torque converter clutch will release and that will disengage the power flow from the crankshaft (flywheel) to the tranny input shaft. This action did not take place and that caused your engine to stall. If that stalling is intermittant, you may need a good auto mechanic to check it out.

 

Hope that helps.

mojoe,

 

I can overrite the idling to Mazda factory spec at 850rpm, locally both Regent motors and MMS has detune to 700rpm.

[BoneStock]

Hi Silverado/Viper,

 

The clutch in the torque converter will only lock up when the tranny is in the highest gear...i.e. when the car is cruising at a speed of 70-80kph from my own experience. So the clutch will never lock when the reverse gear is engaged.

 

Cheers!

[Mojoe]

Thanks guys!

 

The car couldn't move far last night, thus I had to get it towed to Regent... Went there this morning and they just called... need to change something in the engine (can't remember what it was as couldn't hear properly)... the cost of that part is about $1k plus...

 

sigh...

 

Hey Shag... guess wat?? the idiot actually put Manual Trans fluid into my Auto trans!!!! ... no choice, can't wait for the Amsoil so had to change already.. stupid...

 

sxxt man... I think this is the last time I'm going to a 2nd-hand dealer

[Unknown_G7]

Do you need to pay for that part??

[BoneStock]

" the idiot actually put Manual Trans fluid into my Auto trans!!!! "

 

Wah Lao Eh!!!! Sibeh Jialat!!!

 

You have my sympathy Bro

[Cool]

sxxt man.. I think the Tranny Box is busted up with the wrong oil..

THat explains the leak...

 

[Mojoe]

why would they do that ah? i.e. to detune to 700? Actually mine should be closer to 850 than 700 lah so don't think i need to ...

 

as per my reply to Silverado... just discovered that not only did the idiot who serviced the car last time overdose the trans fluid, they put a manual one instead of ATF... sheesh... really pissed...

[Mojoe]

yup....

 

6 year old car... no choice...

[Yongwd]

OMG!!! They put MTF instead of ATF?

[Mojoe]

tell me about it... now not sure what other damages did it do... sxxt...

 

if need to change the whole auto trans, then...

[Unknown_G7]

Oh too bad!!

 

Is that idiot your mech.?? Can't even tell the difference of Manual and Auto??

[Mojoe]

yup... sxxt... what could possibly be the damage?

 

pissed now... MTF cheaper right? maybe that's why... f***...

[Mojoe]

nope... probably the mech for the 2nd hand dealer I got the car from... cut cost? bloody idiot...
