Desperately needs help for vibration problem

[Lsflsf]

Hi all, i have a headache on my car, hope to get some help or advise

 

Brought this Lancer EX 1.5 car a while ago, drive around and feel have vibration (personally dont like vibrations) rating the vibration density as 35/100 so butt itchy go check my engine mount at a amk autopoint work shop then workshop claims that 3 mount is broken - 100k car 3 years old.

 

Went JB Stockist they only have inspira 1.8L NON ORIGINAL engine mount so brought to try ~ 130sgd, went back to the autopoint workshop he installed then found that 3 matches but 1 dont so lan lan have to ask him to order that 1 piece which he claims to be original to fit in. At night collect car feel than vibration got worse density 90/100 paid $250 for the labour and 1 original mount (so now 3 inspira 1 original)

 

Drive for a day really bei ta han, go back to him then he suggest non original mount have such problem so i said ok then change the other 3 mount to original also then, at night collect paid another $380 for the 3 original mounts and labour (all 4 original)

 

Tested the car, vibration reduced drastically density 5/100, so drove off

 

1st day - perfect 5/100

2nd day - perfect 5/100

3rd day - vib starts to increase density 20/100

4th day - 40/100

5th day - 50/100

1 week later till now - 75/100

 

went back to autopoint he said all is original liao also cant figure out what is wrong, i asked him to check screw tightening, he refix 3 easier enigine mount vibration become slightly better 70/100 but still vibrating a lot, asked him why 1st 2 days ok then after that become worse and worse he say might be what sensor here and there but i dont make sense when it works perfect for 2 days and before i change mount the vibration also much lesser than now, change and become worse. then he say put car and wait which i didnt as i highly doubt his efficency

 

Now after 1 more week vibration becomes 80/100 le, then in D density is 80/100, in R density is 90/100 in N density is around 70/100. Thinking of going to stockist personally to change the engine mount to all original again what do you think?

 

Please help i already wasted $720 for this problem that usually people spend $600 on. and new original mount is gonna waste me $600 again

maybe u want to have a second opinion....no harm done asking someone else to check this for you

[Zyrofillica]

check spark plugs? sometimes vibration cos one of your pistons not firing properly most prob sparks.

gearbox mount need to change too?

[Elmo]

If the new mounts can get thrashed so fast then should not be mounts' fault. Could be the previous owner did some ECU tuning or piggyback and the idling and AFR all out of sync when demod? Try pumping a higher grade petrol first and if vibration reduced should be confirmed as tuning issues, and bring back to C&C to reset if they can.

Else you can try a pro-Lancer wkshp to troubleshoot once and for all.

Bro. Why not just go c&c? Save all the nonsense headache.

[Davidtht]

Did you check your rims? If the rims are not balanced, it will cause vibrations too

[R_aquarii]

how did you check vibration density?

is the vibration worst at idling? switch to N during red light and see if there is anymore vibration

 

[Detach8]

engine mount, gearbox mount? bad sparks? ecu kena remap vibrating like mad? i think all these need to check.

that said, mitsu cars are known to be noisy (and hence vibrates a bit)

are you using shell? try switching to esso 98 or spc 98. i have found shell pretrol making my engine noisy too.

Vibration can be due to few things, not just your engine mounts

 

Check your air con compressor

Gear box oil

Steering bush

Lousy engine oil

Lousy sparks

Lousy tyres

 

Anyway, your WS is useless la. he should check on the above items when new engine mounts are not solving the problem

 

Go to another WS. Go to MIT forum and ask around.

 

And I think u made a mistake of buying JB stuff.... Non original somemore..... Big mistake

 

Dont be penny wise, pound foolish

i am still trying to find a good ws since the one i went to seems to be completely failed.

checked. spark plug seems to be in good cond according to ws.

Hi my ride i tuned with unichip before changing mounts, all is good before unichip also, the only strange thing is it work perfect for 2 days then slowly degraded after that only

according to lancermotoring**** c&c is useless. i went there with a problem on my picanto i previously drove, their reply is worse than what a normal ws might comment.

Cant be as if stationary once engage R the density increase when car is still stationary

If during traffic light at D intensity 80/100 but if switch to N drop to around 70/100

I am using unichip tuned to esso 98. noisy i can understand as all ex i been in is noisy but my vibration the most hiong.

air con just did flush only. gear box oil checked healthy, engine oil racing type. sparks iridium, tyres maxxix perfect sym. About the jb stuff i already realised its stupid to buy :) just trying my best to solve the affecting problems

[Lsflsf]

oh ya i just remember if at traffic light D mode, i will get around 5 sec of density 80/100 then the density will increase to 90/100 after the 5 sec till i move off then return to 80/100

Get your tuner to look at it again. Happened to me once after tuning, CEL came on and used Scangauge to clear. After that kept stalling until ECU relearn.

Yours an auto?

Could also be Unichip wiring came loose.

Just curious: Does your tuner's name start with 'A'?

 

[Rb26dett]

might be maf sensor dirty thus causing rough idling?

 

[Detach8]

i would suggest you undo the unichip FIRST.. it might be that there's too much spark advance at idle

if you feel like your car shakes / vibrates alot while at certain speed only esp when you try to accelerate, then it might be faulty drive shafts. Previously i got such problems with my current ride

Yes auto, tuned by CH Mot***, all is working fine around 2 weeks plus after install. This only happen after i change my mounts.

Ok note check MAF sensor.

Undo unichip? how? unplug the wires?

hmmz its actually a constant density and density only changes if i switch to R 90/100 or N 70/100 or D 80/100
