hi

 

i'm driving a 05 carens and today after starting, the car vibrate quite violently. even when driving at expressway, it will suddenly jerk for 5-8secs then become ok. it comes intermittently when stopping and driving,

 

what could be the prob?

just changed plugs for 3k km.

is it the plugs? cables? gearbox?

 

thanks

why dun u let it become more worst first .. then easier to pin point .... but basics like water and oil level must do ... the rest can consider wait and see .... when fuel pump fails you can crank your engine but it will not start .... so if it fails while driving the engine will just stall and will not restart.

 

Let it become worst easier to eleminate. Now all guess work ... by the way got engine check light come on or not ?

The cause may be due to yr mech pulling the spark plug cables out without using a proper pulling plier, one or more of the cables carbon conductor may have suffer internal fracture resulting in intermittent high resistance to current flow. When the cable is hot the fracture just simply narrow or close up and the resistant is reduced. Just ask the mechanic to use a multi digital meter to check the cable resistance. Compare all the cables , they should not vary more than 10% in reading.

Fuel pump is the pump in ur tank that supplies the pressure to your fuel reg/injectors..

if that is choking, the injectors wont be getting the pressured fuel and the car could stutter.. [nod]

 

Have to drop tank to replace fuel pump if i'm nt wrong.

Did u use back the plugs of the same 'heat' rating?

is the problem a sudden thing or has been all along your 3k km..?

 

could be a ign timing issue.. any other mods or changes to ur car?

if not can try resetting the ecu by pulling out the ground frm the batt..

how old is ur ride anyway?

 

fuel pump got 2 type, submersible or inline. submersible comes with the fuel filter.

 

difficult to replace? let's say u need a mech to do it for u.

 

if old ride, then i see no harm to replace it anyway.

 

----------

 

cheaPest is to check the distributor cable. did u spray water into the engine bay without protecting the distributor, it might kena water damage.

 

next cheapest is to replace the intake air filter. check.. did u install bonnet protector? check the area near to the intake air, if the protector collapse down, it may restrict air.

 

also plug in a voltage meter into the cigge and monitor. if off the aircon, and car dun shake, then is confirm aircon compressor got problem.

 

otherwise...

 

if car steering vibrating not moving, and open bonnet, entire engine block is shaking, then engine mounting up lorry, need to replace. how much? mounting tat r pads only chirp, mounting that hv hydraulic more expensive. ($80 vs $250)

 

--------

 

if TB is electronic control one, the motor may up lorry. expensive to replace (ard $800 for lancers)

At what speed were u travelling??? if more then 100k/, somebody up there reminding u to slow down.... [laugh]......on a serious note,did any of ur cables came off, or the plug is of the correct spec? Car is still too new to develope any mechanical problem.

It seems like the spark plug cable is lose. My father car some times ago have similar problem and it is caused by the spark plug cable not properly plug in after servcing.
