The last two have been by the same person yes (the only persons looms that I've never had an issue with is Ian Spotter) , the previous one was a non existant crimp on no3 injector, don't have a clue what's up with this one. Trouble is you end up suspecting it's plugs, crank sensor, phase etc etc and by the time you've got down to diagnosing the issue you're into a lot of dyno time and why should the customer pick up the tab???????

Poor workmanship was the last one, don't know with the current one.
