Hey guys,
So my car developed a problem where when i’m slowing down foot off the gas, the car chugs and bucks back and forth until the rpms get low enough and it stays steady.
My fuel pressure gauge fluctuates from 20-40. While this is happening.
I have absolutely no idle or wot issues. Car runs fine.
I have swapped the tps, iac, fpdm and plugged the egr, none of which made a difference.
What could it be?
