Hey guys cans gals my 05 lgt L has 85,000 miles with a 5eat love it to death but it's giving me problems it has a single exit invindn n1 exhaust and mid pipe has stock up and down pipe and a drop in K&N filter any help would be nice😀
1..It idles fine in park somedays other days it will vibrate you out of the seat? Like the car shakes and fills like a miss fire?
2..under boost to the floor (stock car) will surge and jult and buck?? But it holds boost perfect peak 12.psi to 11.5
3..while slowing down or comeing to a coast the rpm drop to like 200 and bounc back to like 1200rpm as if it was a manul trans but it's not it's a (5eat) any idea on this??
4..went had my oil changed and they told me I have a leaky oil pan gasket? And my oil cooler O ring was leaking any input on this would be helpful
