Hello guys

im a newbie here

I have this LS 430 that caused me a lot of headache to fix and get running smooth

the problem started with cylinder misfiring
I used OBD to check
errors were
misfiring detected
cylinder 2 misfiring
cylinder 7 misfiring

Plugs are in new condition
Ignition coils all operate in very well manner

the problem in the vehicle has developed over time

now, whenever the engine is started, it starts and shuts down

thnx to all

 

Did you get it fix maybe you should check the injectors.

 

Since you stated that the plugs are in new condition. Did you recently change it out? Did the misfire issue exist prior to the plug change? How do you know that the coils are working?

I'd suggest switching the coils with the ones working.

IE. #1 with #2 and #7 with #8

If the misfire follows the coils, then, you know that the coils are the issue. If the misfire does not follow, then you know it's to do with plugs or something else.
