@Shern The car has never had the injectors pulled or tested before. Me and my father have not done a compression test to my knowledge. The timing chain was replaced in 2014 by an ASE Master mechanic so I know that the timing chain is good. I have run biobore and startron to clean the fuel system but I know that is not going to deep clean the IP or the injectors like a diesel purge. We have also never done anything to the IP timing since we have owned the car
