FYI strange misfire in my ram 5.7 hemi
Hello, I would like to share my experience. Hopefully, it will be beneficial
I have RAM 2019 5.7 with CAI, Lt headers catless,, ATI dumber pulley , single exhaust.
the issue ⚠️ check engine light blinks four times in specific situations, especially in the mid-afternoon mainly in hot weather
And when I accelerate on a hill or In the event of strong wind hitting the front of the car (engine load)
However, I was lucky I was data logging when this happened. Unfortunately, Nothing appears, no knocks,fuel just fine
I returned to the tuner multiple times Where; he was checking the vehicle and the tune; everything seemed Good.
During that time, I changed the exhaust from single to dual, And guess what?
For some reason, the problem disappears and the truck runs even better Most of the time the AFR at 14.7 !
I don't understand!
The previous set of the single exhaust has no restriction free-flowing why causes misfires??
