   ok posted up a thread a while back, where basically car is fine and dandy till its a lil cold when driving round every now and again as you accelerates it hesitates for a second then carries on, and prob wont happen again for a while.
   
   now in last year map sensor, icv, coilpack twice has all been replaced. also serviced regular so all plugs are replaced regular althou they are due a change in feb/march time.
   
   im thinking injector rail maybe blocked but it don't happen that often so cant think of what would cause it so randomly

   If you have access to a fault code scanner that maybe worth a shout.

   As far as I'm aware alts fine as it was tested when my battery was dying so guessing that's all good.
   
   Only way I can describe it is its starved of something for a very brief second then returns to normal

   Not a dodgey connection on the fuel pump and every now and again it just loses it for a second? You taken off and had a look at the throttle body and inlet manifold, make sure all of that is clear?

   ive had throttle apart and still clean from replacing idle and map, would there be any other signs of the fuel pump? as car don't cut out just drops revs but rev counter don't drop as if ive put my foot on brake that sort of feeling.

    again these are all changed regular, but would it be that random if it was blocked? I drove car to work 5 days outta 7 roughly and could happen twice or not at all and only lasts for say max 5 secs then all normal again

    Yes that is what mine did, I did get more pops and bangs when changing sounded awesome but yes did fix the problem until I got a new sensor

    so in theory unplugging it would then make that problem disappear, what actually breaks them cos I have a idea that it was replaced 2 years ago
