Re: 4G91 Gang.. convert throttlr body perdana to 4g91

I had not reading in this forum for quite some and just got some time to glance through last few pages posting. My full tank ~rm72 can give me ~610km with 75% highway 80-90km speed . My mechanis told me my piston ring got faulty and need ~rm500-600 for repairing. How to tell if the piston ring is faulty?

6A10 not tt meh~sorry that wrong information given,thanks sifu alvin~

oooo...
u try to check the alternator of your engine.... see the charging is full or not.....
cos ur car current load is high..... u are using HID / have u change any big size bulb or having sportlight......

another things u need to change is the spark plug cable....
cos it will also make the idealing low......

good luck bro.

Ya, ~15km/liter with > 75% highway. You are right that is does slowly eat up the m oil and white smoke emitted. At 1st the white smoke was quite bad and the mechanic asked me to change valve seal which cost me rm200. The smoke termendously reduced but when climb up hill, the white smoke is as thick as mosquito fogging by majlis perbandaran. So, the mechanic did some testing by opening up engine oil cap while the engine is running, the engine just die off and he confirmed that this is piston ring faulty. Just need 2nd thought to confirm if what he said it true.

after swap the engine, my father sent it to service change engine oil, gerbox oil, plug, etc etc....after done all refreshing thing still no pick up..is it problem came from the extractor??

 

[naked racer]

yea i see the lines on the cam gears and the bottom pully but doesnt it need to be a certaint number of teeth between each pully? also the mech i took it to is having trouble with trying to time it right because the motor was never released here in aus and its realy hard to get a workshop manual for a 4g91 carb

so my question is do i need to count the teeth between each pully or can i just wack the timing belt on anyway i want...

funny,coz when i change my timing belt the last time,the mech showed me 2 marking on the cam pulleys, and on the valve cover...must be align...and if im not mistaken,there's also another mark on the crank pulley,..if im not mistaken..but mine's fuel injection..sud be d same i assume..
anybdy else wana chip in some ideas?? :hmmmm:
wonder where is everybdy?

Hi to all 4G91 gang,
I have a question here and hope to get some advise
When my manual car engine running idle parking with free gear, i lift up the car manually turn my front wheel spinning. I notices the RPM increase. Is this normal?

With this condition, I driving on the road when my car still rolling forward with free gear, my RPM stay at 2k. Only my car totally stop, the RPM drop back to 0.8-1k. What causing this to happen? TB or ECU?

 

[calvin9683]

wuhaha....
wat u says dun seems to b a prob le....

hackcremo...i never drive an auto 4g91 before....
but the gear shouldnt b sluggish as compared to 4g15 auto....
mayb u should check on the gearbox....izzit 4g91 auto box or a 4g15 auto box???

naked racer....
the 4g9x series r almost all the same....
i believe there's 4g93 from where r are....
over here, the mechanics change belts with minimal markings....
guess they r too used to it.....
