Re: 2013 Chevrolet Equinox 2.4L bad injectors?
Posted to Technical Discussion Forum on 12/28/2020 12 Replies

Hello all, happy new year.

Well I have found some answers on this equinox but unfortunately the mechanic that initially worked on the vehicle has come to pick it up before we could actually fix anything.

One thing I must clarify that I didn't initially is that this vehicle would run on propane with the fuel still enabled, and injectors working. If I would disable fuel I couldn't really get this thing to run at all, I'm sorry I was not more specific about this before.

After digging through the PICO waveform library I found a good known timing waveform of a LEA engine. [2013 Chevrolet Equinox LT, ECM/Inputs/Outputs Waveform]

[2013 Chevrolet Equinox LS, ECM/Inputs/Outputs Waveform]

This is the Timing waveform from our 2.4

Again we don't have the car to work on any longer but still wanted to post what we found.
