Right Bank Fuel Injectors Misfiring

OENET · 07-23-2019, 04:16 PM

Hopefully someone on here has experienced this.

I have been tackling a misfire/increased emissions errors on my car for a few months now. Finally got tired of it and dropped it off the shop since Friday. Just got off the phone with the tech and they informed me that the driver side fuel injectors/rail are not functioning. He has narrowed it down to a faulty ground or the ECU...Has anyone else experienced this?

Car has about 98,xxx miles on it.

I've done the following process of elimination prior to today's update:

TAs checked out good and in working condition
Replaced spark plugs
Replaced the secondary air pump mass air flow sensor and hose
Replaced both O2 sensors
Replaced fuel pressure sensor

Update - fuses and wiring checked out for the injectors. Tech is now leaning towards the ECU and trouble shooting. Hard to imagine that is the issue if the left side is working.

Anyone have any insight?
