i am interested on the CAI too, seems like a simple upgrade then everyone can start with. Or is there any commercially available CAI for LMST?

Guys my LMST got a problem during starting. Here's the case:

1. Turn key to start engine, engine cranked and start within 1 second.
2. Dies of immediately (around 1 second later) after ignition.
3. Attempt to restart, turn the key, engine cranking sound is normal but engine still does not startup after 5-6 seconds of cranking.
4. Rest, then retry again for Few intervals. By luck after few tries the engine manage to start without really do anything.
5. No problem throughout the day if stop and restart,

So generally this will only occur after my car is parked for a long time (over night) and not every time. I sent my car to service but they did not manage to find anything plus they started my car without problem and did a regular service.

i not sure if battery problem although my voltage meter gave reading from 10-13v plus the cranking sound is normal?

i suspect it could be fuel not reaching during starting, something like a bad fuel pump relay?

Hmm my battery is near to 2 years. Just that i felt if battery prob it shouldn't be able to start easily at first right away. Will look into it, thanks!

Carburetor... hmmm, i thought of it before since i never done any maintenance on it so far. Fuel filter just changed during the service. I think i will ask the workshop to service the carb and see how it goes, thanks !

hmm u mean these? i saw at youtube they use those liquid based "Professor" to clean the carbs

yeah i brought to mechanic and they told me they can only do basic cleaning, not those thorough one like remove all the parts. i guess that will do, thanks again! Hopefully these few days can see result.

Weak fan isn't it relate to the blower? i thought was the blower so i removed and clean it up myself (apparently there is some leaves and small branches stuck on it and also dust )
i cant really say the wind later become big tho but my aircond used to have weird sound like struggling to blow when max fan but after cleaning it, no more.

owhh yeah now i get it, i guess the evaporator part is harder to reach.. have to ask the shop ppl to clean.

talking about fuel consumption, my 2007 LMST best is 13km/l fully highway and normal drive 10-11km/l. So far mostly on the speed range of 90-100km/h with rpm 3-4k.
think i need to do overhaul or something?

Hmm after i check 100-110 to hit 3k. well, really cant compare with other car since totally diff engine.

Fully stock?

i changed mine last month 185 60 14 Hankook H308 around RM130+ per tyre at tyres Pro Malaysia

Yeah, its the cheapest from their offer, u can fb msg and they will reply with quiote.
I Changed all 4 which includes tubes, balancing and alignment. My fren changed 2 only last time and alignment balancing not included.
I have not much to comment on tyres coz this is the first i change all 4 together. (my previous tyres silverstone Synergy M3 hardened after 2.5 years)

So far no visible white smoke and need to check the spark plug. Noted for the advice, let me see what i can do.

1. I have this similiar problem last time, i believe is call Pinging which the engine combust late/early, i asked my mechanic to advanced the timing a bit (late combustion) and it seems like solved the issue, not sure if sifus ard here agree or not tho.
2. I have this problem too, once the engine rattle/shake when turned off, the next engine startup will be difficult. i believe the problem is incomplete combustion or fuel residue that causes this, thats why when off engine some combustion still going on ?
so far i always switch off aircond and and rev a bit before switching off engine and no problem for now.

I think Alcyon is correct, retard the spark timing instead of advancing it to compensate for pinging. I asked to combust late but used the wrong term, it's actually retard the spark timing lol.

Rev a bit only...

it's more than a month now and no recurring problem till now, cleaning up the carb solved the startup problem, cheers!

i wanna mod LMST to decrease fuel consumption instead lol

you tune it yourself? i am wondering if can find someplace to tune it.
