Default Engine back firing?
What can cause back firing through the exhaust on throttle lift off?
I get a nice loud pop between shifts if I'm on on it a bit and on deacel it's a steady series of pops on both sides. I've got slip-fit header to sidepipe connectors, so I know I have some exhaust leakage. I know that cool air getting sucked into the exhaust can cause it but wondering if there were other things I should check. Checked the timing and it's fine.
Thanks
Matt
