odd, sure they are genuine? weren't off ebay for about £40 for a set?

 

[williams-ant]

The advert said they were genuine I think they were about £25 each

Tell a lie they were £46

i'd be suspicious at the price. have they got the logo molded in?

 

[williams-ant]

Yes they do, but all working now so good to go. Just put the car up on gumtree

If the injectors werent in magnetti marelli bags they are probably aftermarket knockoff

I did, first thing I did. As above though, one of the new injectors that I fitted turned out to be faulty!

@ Bashracing .......
I have checked the compression it's 180/195/180/180 for 1,2,3,4 ..... tested with all plugs out running engine on starter motor until the gauge maxes out
I have checked and swapped around the plugs (fairly new)
I have changed the coil for new
I have changed the HT leads for new
I have changed all four injectors for new
I have swapped the O2 sensors around
nothing seems to fix it .......
=> flashing engine warning light ..... only at low speed/stop/start .... goes off during any continuous use after a few minutes .... no power loss at any point
error message is alway 'misfire cylinder 1'

Well for completeness ... in case someone comes back to this thread .... The car if fixed for the price of an inlet manifold gasket !!! seems there was a small leak, that was enough to confuse the electronics at tick-over with no load ...... IF you have the same problem it's a lot cheaper to start with this than injectors, etc.
