It could be that the cable itself is intermittent. Every time you reseat/clean the connector, the disturbance allows the cable to work for a while. If repeated cleaning/reseating doesn't work then I'd suggest the problem isn't the connector or that the connector is no longer serviceable (assuming you've not made an @rse of the cleaning). How many miles are on the clock..is the injector past its best? -- Z Scotland Alfa Romeo 156 2.4JTD Veloce Leather (sold) 'Oil' be seeing you..

I've done nothing to render the connector useless...yet. I was considering doing so but I had also wondered about a cable fault. The way the thing is arranged you can only 'disturb' a very short length of wire when 'jiggling' so if there's a break in it it should be fairly accessible. How do I make such a diagnosis?? Any suggestions please? |

Any suggestions please? Replacement would probably be the only sensible way. -- Catman MIB#14 SKoGA#6 TEAR#4 BOTAFOF#38 Apostle#21 COSOC#3 Tyger, Tyger Burning Bright (Remove rust to reply) 116 Giulietta 3.0l Sprint 1.7 GTV TS GT 3.2 V6 Triumph Sprint ST 1050: It's blue, see. www.cuore-sportivo.co.uk |

I'll add my experience even though the above throws it a little.... I had intermittent misfires due to dodgy injector connectors (well, probably just one but cure-all was applied) on my 147 - cured by securing connectors with cable-tie to keep pressure on the mechanical connection. Fault started at around 65k and car ran nicely through the next 100k miles so probably didn't do any harm! Oh, and hope to be back in the fold next year, new car required March.... |

I have modded it and for now it works ok. If it happens again, I will try you solution. Thanks for your input and good luck with the new car. |
