a while back i installed my 435's, but found that with out upping the timing the laser cut dvs were too much so i pulled them and put the stock dvs back in, and all was good, until about 4 days ago the truck started bucking and smoking white smoke again, i figured my timing had slipped back, my tranny needed some adjustments so i hadn't driven for a couple days, after my tranny was back together i went for a test drive, still white smoke at idle but no bucking, basically ran decent, today i put my new lift pump, basically for the heck of it, started the truck up and bam!!, no smoke, no bucking nothing, so why would my truck start bucking and smoking and then stop with out even doing anything. before the new lp the bucking had stopped just white smoke. thanks

nobody have any ideas??? i still plan to do the timing, but im curious as too why these syptoms would occur and then go away, should i get another set of injectors and see if they run better?? thanks
