Hey guys cant figure out why i cant gat this thing to idle in drive or reverse. park is ok put still rough. does not have any get up and go. gen 3 5.3 aluminum block, cam, springs, pushrods, 3200 stall. it goes good at mid throttle. wont do anything if you step on it it wants to choke. i found that when putting it in drive it goes full lean, when im out cruising sometimes it will go full lean when i step on it. need to let off and go again. can some one have a look and see what is going on.
