VN shuddering when accelerating

[STYALR]

hi ive had sum help from u guyz aleady but the problem is still happening
When i start the car it idles really rough and then when i go to take off the car lunges forward and struggles 2 move feels like it wants 2 stall.

At the lights it will (sumtimes) stall but i can start it up straight away wiv no hassles.
wat ive noticed is the leads which come off the COILPACK are a lil burnt one of the leads is corroded a little cud that be the problem?
and also on the bottom right side of the ENGINE where there are 3 leads which come out from the engine 2 of them are touching and seem 2 be a lil burnt out, wud this be spark plugs and ignition leads which need replacing and if so how much for new leads and spark plugs installed by a mechanic?

i'll also add when i take off car jolts so much it feels like its not moving but only when i accelerate hard if im gentle on the accelerator its ok and when im driving at a constant speed say 60kmh its fine.
any help wud b appreciated thanks alot guyz

not a fuel blockage or anything is it?

yea man its most likely a spark problem. i wouldnt bother paying anyone to change leads and plugs. it'll take you 10mins at the most. a set of leads and plugs (correct me if im wrong anyone) should only cost aroulnd $50. just remember which lead goes to which cylinder! i change my plugs around every 6 months, after a while the engine seems to run a little rough. i have been told that commodores do tend to have a problem with spark!

As long as it's just the leads/plugs you should be fine. And yeah $50 is about all it should cost you.

One other problem which might be causing it is the coil packs. If they are on their way out that could be doing it.

Also, if you have an engine immobiliser fitted check all the wiring for that. My one was playing up, just a dodgy connection, and the left bank would cut out while I was driving. In all fairness it still drove on 3 cylinders, but it ****ed my catalytic converter up in a day.
