im having the same problem with my corby coupe i think. does it feel like a flat spot in your acceleration on during certain rpm's?

 

[pagey]

yeah between 3000-3500 rpm sometimes it will do it sometimes not its so annoyin lol

 

[Big_daddy]

Have you checked the coil packs? what did the diagnostic show?

 

[pagey]

yeah done them but not genuine ones... just said intermitent misfire .. no engine managment light on

 

[shaun8215]

i had something like that. but i fitted a boost gauge and it was only boosting 0.5lb which felt like it had a flat spot. Do you have a boost gauge?

 

[pagey]

yeah but its broken atm llol might take one off my boost gauges out of my starlet.... you it drops off and then goes back to the full 1.3bar

 

[pagey]

its only starting do this after i changed the coil pack .. so i changed the plugs but no joy

yeah done them but not genuine ones... just said intermitent misfire .. no engine managment light on

you need some one with vag.com, you need to monitor all 4 cylinders for misfire as you are on boost.
Plus some power run logs for maf, boost, cf.

if the gauge is not working, ensure tha vacum line is not leaking, just plump it up as it will effect the running

 

[pagey]

i dont have vag com and dont know anyone with it lol... and yeah i kno the needles just broken..just tried puttin one from my starlet in but there both bloody 64mm lol

[pagey]

[tom w]

may be daft but what about changing the sparkplugs???

 

[pagey]

done it twice lol

 

[tom w]

have you posted a request in the vag-com section? to see if there is anyone in your area ???? i think this will be your best bet as we have covered the common solutions ! it could be electrical loose earth???

 

[Ibiza125]

So you say it started after you changed the coilpacks? And you changed them to none original ones?

1+1= you need original coilpacks.
Non-original ones are crap.
