series 60 is this normal??

Ditto on the coughing. I can be pulling a hill and all of a sudden it will hiccup throw a small cloud of black smoke and then keep right on pulling like a champ. Took it to Detroit Paid the $110........hooked it up to the lap top and everything checks out normal!! Detroit's reccomendation..........."run it till it quits or throw's a code or we can throw parts at it"

 

Mine will cough at 1300 rpm if the turbo isn't spooled up yet. If the turbo is spinning no problem, if I'm a little lazy on the throttle it will let me know with a cough.
I was told that an overhead will probably cure the problem.
How often do you guys get your overhead done?

 

Never, Drive the piss out of them till 1.5 - 1.8 million till it pukes parts. LOL

 

Thats exactly what mine does. I haven't had an overhead in..........um................110k miles

 

I bought mine with 513,000. I have 745,000 now and haven't done it yet but I will soon. I'm waiting until I get to a shop I trust.

 

Mine hiccups around 1200-1300 rpms (usually when I have my foot hard into it). If I back off and excelerate a little slower, no problems. I figure it's the EGR (I got the truck with 400k, it has almost 900k on it). I've replaced two EGRs already, and really no inclination to replace/fix it again. Truck runs good. I get about 6.0-6.2mpg on average.

It's been doing it for around 150,000 miles, so I'm not too concerned until it does it non-stop or when just driving down the road. No codes, no alarms, either. My friend just put $3k into his series 60 trying to figure out what was causing the sputtering and it still sputters (new EGR and CAC, now he's looking at replacing the turbo). Although he's got bad fuel mileage (4.5-5.5). So, it's a much bigger deal to him.

 

Has he had the ECM tested?

 

You described it much better than I did. Mine does the same, if I get into it a little too hard before the turbo spools up. If I back out there is no problem.
It's good to know that it is somewhat "normal".

 

Our 98 500Hp DD does the same thing. Even when driving once in a while it does the hiccup. There is no CEL showing us a fault. Took the truck to DD mechanic and they can't find anything wrong with it.

 

True so true.
