Hello everyone!
So when I start my car (95 SN95 5.0 5spd intake, gt40 heads mild comp cam) it runs and drives fine. If I downshift and coast in that gear for a few seconds it drops a cylinder. Stays that way until I turn it off and let it sit for 10 minutes or so. Turn it back on and everything is fine again until I downshift. If I don’t downshift and just coast in neutral it’s fine. ECM appears to be untouched. I recently purchased the car with all of the bolt ons in place already. I don’t believe it’s ever been tuned. Any thoughts?!? Thanks!
