Hello all,
I have a 2005 60 EFI. I have an issue that has become very expensive and was hoping for some help. My engine starts and Idles fine. In neutral I can take the engine up to 4000 RPM's without issue. If I put it in gear the ignition starts breaking at 3000 - 3200 rpms. I was told by a certified (or maybe certifiable) mechanic the ECM was the issue. $658.00 later the problem persists.I have changed plugs gone completely through the fuel system with no results.........HELP

What do you mean by "ignition braking" ? How does wiring look ? Good grounds?

If the "mechanic" didn't fix the problem.....what does he say ??
