Where's my cylinder gone

[nickC]

Hi all,

Had car off road for the winter.

Just started her up today, which she did on the first key turn.

However she's a missing!! Checked with Datascan, had no fault codes but found that no. 2 cylinder is not firing. I had a quick prod around but before I get going on it tomorrow i though i'd check for a few pointers where to look 1st.

There were no problems before winter break. Still got series 1 PTU but would that show as a fault code?

 

Thank

The most common cause of this after a long period of non use is injector connections, they commonly fir up with a weird green power like substance, identify which cylinder it is by removing a coil pack connection one at a time with the engine running and then once identified clean that injector connection with WD40 or similar, be aware though the injector is 12v live at all times ( even with igntion off) so do not short the connection as it will pop an output on the ecu, if any doubt disconnect the battery whilst cleaning the connections.

mine misses after sitting around for months, but clears after 30 sec's or so, maybe it just needs a run? or will that make it worse? defantly listen more to jeff's advise than mine though whatever you do! ha

Thanks for the replies. Took a few hours but finally sorted it. It was one of the injector connectors, but not the green gunk, i had a break in the wire. Must have gone brittle over winter. Ruddy hard to find. Oh and i shorted it. :(

 

Thanks
