Imprezzive2.5 Posted September 2, 2016 Share Posted September 2, 2016 Hi all, I've been trying to chase down a hesitation issue with my 05 LGT for a little while, usually (not always) in the lower part of the rev band, varying in severity. Currently borrowing an AccessPort from a friend to datalog to see if anything sticks out. One thing I noticed is that almost under any load, the AP shows a positive feedback knock value. I realize some knock is acceptable, especially on gear shifts and low rpm acceleration, but I haven't seen much around about getting positive values. Some of the values are of high magnitude too- from 4 to 6, which seems fairly concerning. I haven't gotten any CELs for the few months I've owned the car. I've tried a few small things, like cleaning the MAF and running injector cleaner to no avail. I have access to the car for the weekend while I'm home and can log values. Any insight you guys have would be appreciated, thanks! Link to comment Share on other sites More sharing options...

Imprezzive2.5 Posted September 2, 2016 Author Share Posted September 2, 2016 Fair points- Swapped in a used motor when I bought the car. Body has ~155k, motor has ~130k miles with what looked like the original turbo. Haven't performed a compression/leakdown test yet, but that's on the to-do list. Car is bone stock Link to comment Share on other sites More sharing options...
