I have it under warranty ( only they take a week to get back) and they already replaced 2 catylitic converters and an egr valve. I dont know if this helps but the battery was low and almost wouldnt start and the battery light never came on (I replaced it). I heard someone tell me fuel injector cleaner might help and walmart has fuel injection service for $20 could I do this and be cheap fast fix (in your opinion)
or should I spend $40 and get a diagnostic test and see how major it is and if I do that can I just take the results where the warranty is I trust the other guy for the test
its not an additive from what I understand they flush it out
