Hello. im new here. took my truck on a 3 hour drive thru the mountains and it started to act like a fuel filter was stopped up. turned it off. started back no problems. got 5 miles and it started again. no service lights. no nothing. try to thottle up and it derates. turned of for 5 seconds and ran good till i got another 5 or so miles. i saw on your sight possibly ipdm relay. swapped and it did same thing. the next day it ran fine till i got about 50 miles into trip and it done it again. ive been going thru this sight and i read what scares the hell outta me about the cats. i have no warranty being i got 166k on it. i changed spark plugs. cleaned thottle body. cleand maf sensor... now i got a code p0430. which is the cats. is there a resonably priced solution for these. or am i screwed? :bangit:
Catalytic converter?

The p0430 is a cat code, catalyst system below threshold.
I think your cats are going bad, if its just happening now w/ 166K on it. I would get a set of long tube headers & illuminate the cats all together or replace the cat's with high flows, but to do that your going to have to remove the OEM exhaust manifolds anyway.
Good luck & keep us posted!

If you do what gweasel said, you won't have to worry about cracked manifolds either. Longtubes are around $600, cats are like 80 a piece (IIRC) then install. Replace them before SHTF haha
