Where Can I Find A Proper Tuner / Mechanic?
Discussion
I've just bought a C5 Corvette with an LS1 engine - a pretty simple engine
I bought it cheap so expected to sort the odd issue although I'd seen the bills that came with it which come close to £10,000 in the last 1,000 miles so it has been "well" maintained
It has a misfire - random, multiple cylinders
Looking at the receipts this has been fault for the last 1,000 miles / 3 years that the previous owner has been chasing
It has had plugs, leads and O2 sensors (multiple times)
I suspect fuel injectors or coil packs or do they suffer with ECU issues ?
I'd rather someone put it on the modern equivalent of a Krypton tuner / oscilloscope rather than throwing parts at it
Can anyone recommend anywhere - preferably near the Midlands

My EFI bikes don't tend to actually misfire, but after not being used much in the winter, it's noticeable that they are less smooth at idle/small throttle openings and grumpy in slow traffic. A few tanks of fresh petrol makes a difference.
I've recommissioned a couple of EFI bikes which have been unused for a while. Getting the injectors overhauled was worthwhile. Cleaning out tank and pipework produced a lot of 'stuff'.
New hoses. Filter. New fuel pump in one case. Check fuel feed pressure.
Modern petrol doesn't always keep well. Some vehicles seem to be better than others at sealing the tank from the air.

If not coils, could be a broken valve spring which I've heard can give a random misfire symptom on the LS if all ignition and injectors are OK.Looking at the receipts this has been fault for the last 1,000 miles / 3 years that the previous owner has been chasing

There was a US car specialist in the Midlands, but can't recall the name, think it was West Midlands somewhere?
It has a built-in code reader, via the dash
I've been reading up and it can be many things from the crank sensor to the Torque tube bushes !
We used to have an excellent mobile mechanic with a Krypton tuner in the back of his van and he always found the problem, unfortunately as with everyone else I used to use, they've all retired or died

Not really good with modern stuff but even though you can read codes on the dash it sounds like you need to find someone who can plug in and read live data.
Any idiot can read fault codes and change random parts but real fault finding is a skill that is hard to find these days.
Good luck.
