I have a 1994 D250 Diesel with 450K and it still runs like new. I also have a 1999 Ram 1500 with 133K that does not run so good. I got it from a guy that bought it new and tricked it our with a Warn wench, new steel front bumper, running boards and inverter. At that time it had about 13K on it in 2000. Nice quad and comfortable to drive. I had three transmissions put into it in by 100K. Still like it though.

Thanks to all for this forum. I hope I can resolve my issue of it not wanting to go over 70 and giving me P0300, P0304 and P0306 codes, but only when I floor it and try to get it above 70. IT will down shift and I can be quicker on the throttle and it will kick down RPM to 4K and and throw the codes. Runs great up to about 60. Mileage is not suffering. Replaced the intake manifold gasket way back with maybe 50K.
