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:

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

Damn, those are high!! So you would still recommend the 2.25 instead of 2.5" cats with headers?

Yes, 2.25" same as the collectors on your headers.
