The p0089 keeps coming back, it will crank up with a puff of smoke and idle up around 800, then after a short time the idle falls back down to 600 something, sometimes you can get in it and it will run decent and other times it wont have hardly any power, cant hardly get over 45mph, after doing lots of test im thinking its gotta be the rail pressure sensor or fuel pressure regulator. all the injectors are checking pretty good... Also sometimes you can shut it off and crank it a minute later and it will run fine
