OLDSKOOL78302 Posted August 27, 2011 Report Share Posted August 27, 2011 wait wait am i reading this right you took off the cat and put on a glasspack in its place?? if thats so then that is your problem. your truck is an 01 which means that its obdII. which means that there should be a pre cat and an after cat o2 sensor. since you took off the cat the after cat isnt seeing the right info which is making your truck run wayyyy rich which is making it bog down and backfire because the engine is getting way too much fuel. put a cat back on your truck and that should fix the problem. I forgot about that.That could be it to.

theTank77 Posted August 27, 2011 Report Share Posted August 27, 2011 might i also suggest along with putting a cat back on your truck seafoaming your truck too http://www.youtube.com/watch?v=vRAV5ln5cUc if you dont know how watch the vid. seafoaming your truck will give it back some horsepower and will make it run smoother after its all done. just remember you have to change your oil no more than 100 miles after doing it my build log Link to comment Share on other sites More sharing options...

vettedude102 Posted August 27, 2011 Report Share Posted August 27, 2011 If you check your oil and it looks milky you definitely need to change the oil. 2 polk audio 4x6'skenwood head-unit 220 amp Mechman alt1979 Corvette 2003 corvette z06 alpine radio and the bose system that came stock Link to comment Share on other sites More sharing options...

I have a 2001-s10 truck and i cut out the cats and put pipe there and just put the o2-sensor back in the pipe and i have no code and it runs better than ever, when my truck was runing like that ended up puting fuelpump in it and changeing the pluges thay where fouled out, any way you do not have to have a cat on the truck 4it 2run right, Link to comment Share on other sites More sharing options...
