Yea I have been smoking for a few months, and found out it was my injectors, have 4 bad ones, looked every where for injectors all very costly, and alot of remans, so when I asked my mech. he said he only used new from dealer, so I called the dealer here in Oakdale, CA. and asked if the injectors where new or reman. and was told they where reman. for 350.00 each and a 150.00 core charge, and that they are boshe remans. I got mine on ebay for 231.00 and no core, so is there anyone that you guys know that will buy the cores, if so please let me know, getting ready to change them out after thanksging, so any help would be great.
