zl1 2019 problem , uneven engine operation

zl1lukaszek · 05-29-2021, 01:54 PM

Hello

I have a problem with my Camaro zl1 2019

I bought it with a damaged bumper at an auction in the US

When I started it, it worked very unevenly, mrygal check engine
there is a misfire

It turned out that two wires were removed from the ignition coils

I put it all together and it's okay but

A car with black smoke
Another point when sitting inside the car feels the slight uneven running of the engine

There are no errors in the computer

Is replacing candles with new help?

Sure. Use only Dexos 2 candles though.

Heh, it's a funny term I know, but spark plugs are literally called "ignition candles" in some European languages

(zl1lukaszek is obviously Polish or of that descent)

after changing the candles, these are the parameters of the car

I still feel a slight vibration at idle

Your idle sounds okay to me. To be honest, however, it's hard for me to hear any discrepancies in these files, because they're very quiet and I had to jack up the volume into the distortion or background interference zone, sorry.

Maybe someone else with a ZL1 will pick up something.

Can you put a scanner onto the car and log the ignition timing and throttle position?

The 6.2 V8 in both LT1 and ZL1 models tends to have a slight vibration at idle. Its due to the cam....
