Matrix rough running stalling

My 2010 Toyota Matrix with a gasoline engine is having issues. At 89401 kilometers, it's running rough, stalls at idle, the check engine light is on, and it jerks when accelerating. I think it might be a bad ignition coil, maybe from a bad cable or plug. Anyone else seen this?

Sounds familiar! I had similar symptoms on my Matrix. Check engine light, hesitation, the whole shebang. Does it feel like you're driving a bucking bronco sometimes? I would start by looking at the ignition coils and their connectors. They can get corroded or cracked over time.

The 'bucking bronco' sensation is spot on. Could you tell me which ignition coil(s) were the problem, and how you diagnosed it?

Well, I didn't have the gear to properly diagnose it myself, so I took it to a trusted mechanic. They ran some tests and confirmed it was one of the coil packs failing. Best bet is to get it checked out at a workshop.

I took your advice and went to a mechanic. They found a bad ignition coil because of a bad connector. Replacing the coil and connector cost 95€. It's running great now.
