hello
I have a problem with my 02.
it started a few days ago.. I blew a vacuume line off my aic the truck deaccelarated quickly and ran ok as long as I did not go under boost.. I repaired the line and all was well. so now it is acting the same ..but the line is attached ....if I go under boost it almost sounds like a backfire through the intake. so I been keeping out of the s.c. Idle is good no vac leaks. appon acceleration or maintaining a high rpm 2500+ and holding it there I can feel the truck I would almost say miss... watching the obd I can see the o2 spike down when this happens.
I thought of the TPS since the range is from 9.4 to 60 I was under the impression that the range should be to 80.
the o2 is a few months old.
I am going to be logging more data when I can.but I am moving this week so it will be difficult.
any ideas?
