If you can isolate the puff to one cylinder, you may want to remove the valve cover and inspect the rocker/assy for bent push rod. Did you adjust the timing at all.....black usually means too far advanced. Have you got clean fuel and filter with a healthy dose of additives. When engine is just started cold, remove the timing advance wire, listen and watch for smoke, tell us results.

Find and fix the source of the puddle and try cracking the injector lines open to see if the miss goes away.

I wouldn't say I had a miss till teh fuel leak was fixed adn the truck ahd been driven gentlya few miles to purge all teh air out. AFter that, if youc an isolate a dead cylinder, first swap that injector to one you know is firing and see if the miss stays with teh piston or follows teh injector. Now you can isolate a miss this way...crack the injector line about 45* or slightly more with the engine running at idle. You should notice a significant RPM drop at every cylinder, which should be approximately the same. If one cylinder's fuel is taken away and it makes no difference...it has a dead injector or bigger internal problems. If fixing teh leaks and teh injectors doesn't work, pull the valve cover and check out the suspect cylinder. Borken valve srings, bent push rods, and dropped valves were not uncommon with 7.3s due to insufficient oil changes or lack of lubrication due to positive valve seal design. Have a great day.

thanks i think i can do it lol dont think i can hurt it anymore

greetings have you set the timing static at 0 and does the truck rattle very loud
is there a elect timing advance wire i haven't ever seen 1
you can also test the timing advance of the pump by excellerate the motor to around 1400 and with a long screwdriver mechanically push in the lever on the drivers side of the pump that is the timing advance unit it should change if it does not you got a problem in the pump
if it does it took you 2sec
also make sure you get the spring back in the lever if it falls out
a dab of grease will hold it in place until you get back on the sping and throttle lever

tks for info turner i can try that i got this trk last year and it looks as they doctered to sell i get put new cam in and set all the marks but befor it droke down last year it was blowing black real bad and had no power on the hills that is why i think they have set the pump up hi on it it start real easy not a lot of rattle only a puffing sound like hitting on dead hole but when i checked it looks as if it is fireing on all 8 but will try like you said only take a few sec to see thanks john

jhcfun · 03-18-2006, 03:18 AM

just a update got all toghter run a little ruff useing a lot of fuel thank it may be time for new pump but from what i have read on here 132000 miles on it sould replace but other than that it runs good passed smog with no smoke now the next thing i need to do is have tran checked it dose not want to go into overdrive at high speeds but shifts fine in town may be something easy i hope but thanks for all the help john

aaklingler · 03-18-2006, 07:53 PM

Have you checked your fipl? Have you changed your fluid and filter lately? Does your speedo and tach work flawlessly?

cdnsarguy · 03-18-2006, 11:22 PM

You say trans does not go into OD at high speeds, have you tried gently applying the brakes while driving to see if the RPMs go up 200-300 rpm indicating the OD is unlocked when brakes applied as required.

jhcfun · 03-19-2006, 02:45 AM

ok i am a dummy what is fipl??? tack and speed work i was going to take it in to have fluid and filter changed but was told that if i was haveing troulple with tran that would make it worse ?? wanted to ask here frist to see if that ture or not and pete no i will try that and post ,,, on freeway at 65 to 70 it is tacking at 2500 to 3000 when i let off the fuel it will shift or feels like it after a few sec thanks john
