I have, like a lot of people been having running issues with my Vecrta 1.9  (05 plate 43k, owed since new) recently so I decided to start a new thread to try and provide others with links to what I have tried so with may be at the same time trying to resolve my own issue.
It all started about a month age when there would be to odd jerk or miss from the engine while accelerating or coasting up to a round a bout. This escalated into a performance or lack of power problem below 2000 -3000 revs. Above this the engine ran fine. Below this it feels as though the engine is being restricted hugely in some way as though it is being suffocated.
This then turned into a intermittent problem happening on the odd day & then running fine. Finally the "spanner" light came on and the engine management light so I took it to the local backstreet to diagnose the faults by the ODBII. It had a error code of P2279 but as it could be a number of things the local garage reset the lights and suggested that I wait until it gets worse and breaks to avoid wasting money.
After reading a few fantastic threads on here I have tried the following so far.
1) STP injector cleaner in a fresh tank of fuel. (tried this early on before it got worse)
2) Stripped, cleaned & re assembled the EGR following a handy How to Here. ( if you can wire a house hold plug you can attempt this too)
3) Check my swirl valve was fitted correctly. Link
4) Bought the 3rd injector wiring Mod "field fix kit p/n 93189918" (unable to fit this as I require Instructions) see Link
5) Stripped, cleaned and assemble the Air box and carried out the bottom box "Mod". Link
My questions are:-
a) What else can I try to fit / clean or replace myself?
b) Some where it was mentioned that you could clean the DPF as it may get sooted up? Is this easy? Where is it located, instructions please.
c) Can someone provide me with instructions on "How 2" fit the 3rd injector wiring Mod "field fix kit p/n 93189918" ?
d) When I checked the swirl valve they were connected but seemed a little loose.. rocky (forwards and backwards) is this normal play?
e) Is there a comprehensive list of all the error codes anywhere?
I have also ordered a ODB II reader so I can trouble shoot and reset my own codes in the future from ebay. link VX want £64 a time...!
Thanks to all the people that have posted How 2's and to all the knowledgably people out there that makes this forum so useful.
Thank also, in advance to all the lovely people that are going to reply to this thread and help me resolve my issue.
