Abomb Posted May 28, 2020 Report Share Posted May 28, 2020 I have a v7 sti and picked my car up from the tuner today. It has a 20g with 850cc injectors and a 255 walbro. It’s not starting well, it’ll crank 5-8 seconds and not start. It’ll also occasionally backfire while cranking. I have -18 vac at idle so there isn’t a leak, is this a timing issue with the starting tune or am I looking at a different problem? Quote Link to comment Share on other sites More sharing options...
