It was running fantastic. 280 K kilometers ( 180 K miles). I changed the O rings on the injector pump, and put new fuel hoses. Engine begun to shake. If it is cold, runs great. Ones warm up it skips. On a D or R it is smooth, but on Park or Neutral skips. Any advise would be appreciated. Thanks. O yes Engine light came on. I had two fuel hoses connected the wrong way, but I reconnected those properly.
