1996 Toyota Corolla 1.6l engine. I have a cylinder #4 misfire. The owner has replaced spark plugs. Wires. Distributor. Coolant sensor. Injectors were cleaned. I got a chance to scope the injectors and got this weird pattern. I think the ecm is going bad.

The over-all pattern of the wave looks good, to me. The circuit has current limiting. How does it compare to other cylinders? One thing I CAN'T see is pintle movement. Can you take another capture, with a 10ms screen and a one, maybe two, amp scale?

I will try tomorrow. Don't know why my Modis freezes up. I have to restart it once in a while. I've had it for a few months . I purchased it brand new.
