`My is250 is also a piece of crap currently. 2008 160k miles and new spark plugs battery and igniton coils, have a p0304 code, po335 and c1201 (same here). Also says low battery positive voltage but its a new battery. Its basically in limp mode and ive gotten a top engine clean to clear the carbon build up as well as ran a few cans of sea foam through it. I get to about 2k rpm and the gearbox wont shift on time and until i release my foot almost all the way off the gas it will shift. Ive heavily considered an engine swap as of lately due to the fact that my crankshaft position replacement will cost as much in labor as rebuilding the damn thing. Suggestions or experienced recommendations appreciated.
