Vx com rough idle / jumpy / jerky after service, wtf????? 8-/

[vxberlinav600]

HI ALL

my car;

vx berlina 2000 series 1 v6 3.8 automatic

problem:

Serviced on tuesday 30th oct 2012, reassessed by mechanic this thursday, no solution....

service included:

sparks (brand?)
leads (top gun)
fuel filters (brand?)
oil filter (ryco)
new oil (valvoline)

injector cleaner x1 bottle wynns
tank of premium fuel

picked up car at mechanic.. straight away notice idle isn't right, engine jerky / jumpy every 2-5 seconds, when idle and driving at 100k's, does this in all gear positions... it will not go away....Before the service, the idle was smooth as!

Any ideas whats going on? ...the mechanic didnt seem to really care about the issue! wtf!

It is possible that one of the leads or plugs is faulty or the mechanic stuffed one up. Check to see that all the leads are pushed on firmly.

If they are all on firmly try disconnecting each lead from the plug. If the problem gets worse, that plug and lead are OK. If the problem stays the same, replace that plug and/or lead (most likely plug).

Could be a few things mate when I serviced the mrs vt I dropped a spark plug mind you it was not a big drop and that turned out to knacker it one faulty spark plug caused the idle to go erratic like it was begging for fuel like it was running on empty you could feel it when you accelerated.

I doubt the leads are damaged if there new if anything he may have put a wrong lead on the wrong plug if he didnt do 1 by 1.

If the leads n plugs are fine I can the only thing I can think off is he may have put your fuel,filter on backwards?

Thanks accentstencil, Mick1988, thebot123

goin back mon morn to check all s/plugs -- ill mention the f/filters 2 mechanic

i reckon its a bad s/plug, but who knows - nil error codes showing up's a good thing -- ill let ya's know monday night cheers guys..

*SOLVED* you all had the right idea....

Problem was INCORRECT PLUGS installed by mechanic, the gap was prob out too.

So car is running smooth now, a simple 260$ service has turned into a 600$ cost.

I WEN TO RIVERVIEW SERVO, NORTH HAVEN NSW THE DYKES FIXED THE PROBLEM STRAIGHT AWAY....END OF RANT
