Engine Misfires Low RPM and Heavy Throttle
Had this issue come up recently.
Best way to describe it is how you slow down for a turn, downshift to 2nd gear. As you pull out of the turn where RPM is 1500 or less and give it some gas (greater than 25%), the engine will misfire multiple times, until the RPM builds up and then everything is good.
High RPM nothing feels wrong at all with no loss of power. Same low RPM without heavy throttle, and there is no misfire. It only happens if you put your foot into it.
This is a weekend car that gets driven occasionally and had been running great before. 121k miles. I know I should have pulled codes before posting, which I will do when I return home from travelling. Hopefully someone has dealt with this already and it's an easy fix.
