    I'll have the plugs out tomorrow & see. Discovered tonight that the solenoid that operates the gas hat had a realy bad earth , that might stop it opening properly & cause the cutting out.

    Good news there then Paul.
    Certainly the poor earth is a problem.
    On Fi systems, its nearly always electrical faults that are the problem.

    I had that Paul, its usually the relay, open it up and clean the contacts on it as they might just be a little burnt after 20 years
    Check the plug is good on the Map sensor too.
    PS.
    Got the T shirt on broken plugs too

    Plug looks good , sensor don't look like it wants to come to bits or , to be more acurate , like it'll go back together once it's been in bits.

Ask yourself why are there so many early C4 corvettes which were factory fitted TBI now running holley carbs?
    I think you're getting a bit confused here. Early 80s Corvettes never had the TBI system under discussion here, they had 'cross fire injection' which was indeed trouble prone.
    TBI isnt a primitive carb setup either, you're thinking of the old electronic quadrajets which were the predecessors of EFI.
    TBI is a slightly simplified conventional EFI system which has 2 large injectors in the throttle body instead of 8 in the manifold runners.
    Its a good reliable non-performance system for ordinary everyday vehicles.

    Paul,
    The relay is not in the sensor, its usually on the bulkhead somewhere, it will list it in your manual.
    They are usually gel sealed, but will come apart with a little persuasion, just silicone seal them up again on reassembly.
