hello ibought a 99 isuzu rodeo about a month ago drove it for 2 weeks and flex on y pipe broke when i went to go buy y pipe with thetruck it wouldnt drive past 40mph so took it to alocal shop and they told me it needed a fuel module.so bought a new fuel pump and put the y pipe on and still wasnt driving right,here to find out it was the driver side cat coverter clogged ,so i put converter on and truck turns on fine when cold once it heats up it starts to idle really bad and shuts off can any one give me some advice thanks-david

 

ck the other side cat, with a back pressure guage, if ok ck to see if a trans has been replaced lately, o2 sensors hooked up wrong can cause strange problems
