Technical Punto Juddering / Loss of power

[lcdm2808]

Hi

I have a mk3 (54 reg) punto, and have been experiencing juddering of the car, with loss of engine power and flashing engine management light. This only happens for a minute or so each morning.

I have connected a diagnostic code reader to the car, and it detects no stored faults / DTC's. :bang:

Has anyone had similar problems, or have any other ideas for fault finding?

Thanks

Had the diagnostic machine running today whilst my partner drove, got codes P0300 and P0301, random misfire on cylinder 1. Any common problems punto's suffer from in the ignition system?

Spark plugs are due to be changed soon so they will be replaced tomorrow.

Try cleaning the throttle body. also, clean ur spark plugs or replace them! May have a damaged HT lead.

Sounds like what mine does, especially in first gear, i always have to change to 2nd to stop the annoying jumping. Any advice on how to fix this would be great.

When I'm in first gear in my MK2, and going slowly, the Punto whines and jerks forward, only way to stop it is to push the clutch down and gently come off it again. It doesn't really bother me that much, but it would be interesting to know the cause of it.

yup, it's bladdy annoying! Today mine was doing this In 1st, 2nd and slightly in 3rd. I've bought some injector cleaner as I recon they mite have some debris in them as Im always on red lol gnna clean out the t/b as well

I googled it to get those links

wow, this seems to be happening to a few puntos lately!

mine has started to do this too, took it to the garage last friday and it read a misfire on cylinder 2. The garage cleared the code and tried to make it come up again to see if the same fault came up, but as it only seems to happen in the mornings it wouldn't so they gave it back to me without repairing, but was told to bring it back when i could get the warning light back up.

so, its booked in again this friday and will hopefully read the same code so the garage can repair it...The mechanic said something about getting a new coil pack, and this should fix it?

i will let you know the outcome friday or saturday, when its *hopefully* fixed

**EDIT - i have a 52 plate mk2 sporting it that means anything? lol **

As I've said before I'm no mechanic

What's a coil pack and what does it do?

haha, im exactly the same as you, unfortunately i also have no idea...althought a quick google gave me these wikipedia results

[ame]http://en.wikipedia.org/wiki/Ignition_coil[/ame]

[ame]http://en.wikipedia.org/wiki/Distributor[/ame]

it seems to be something to do with converting the low battery voltage to a higher voltage to spark the spark plugs, if that makes sence? lol

 

[Car nut]

googled again and found this

Coil Pack

Seems it needs PROMPT ATTENTION

 

[fubuk88]

uh ohh....well im glad that mine should be hopefully getting sorted on friday then if its urgent!
