stalling on decel

[93turbo_animal]

Just needing some opinions everytime I push in the clutch the truck dies But it will start every time theres no surging like air or anything it just dies when the RPMs are coming down. If I leave it in gear and just apply the brakes slowing down it will stumble when the rpms get to idle but then it will pick itself back up and idle when I push in the clutch

how old is the fuel filter?

I was thinking fuel starvation, bad fuel or an underrunning IP governor. Check the fuel filter first as Calvin said.

typically a dies at idle thing - is a metering valve in the injection pump. Treat it with fuel conditioner and see what happens.

Thanks guys. Thats what I was thinking Travis but the funny thing is it just started doing it right after I had just put the filter back on full of power service. I was also wondering about turning the RPMs up some cause I know when Mel timed it almost 4 years ago he advanced it then had to turn the rpms down so now I'm wondering if with 4 years of wear if its retarded enough that the idle is just to low

 

[argve]

Yep that very well could be because a typical sign that the timing is retarded is that they will die when dropped into gear.

ok Thanks Travis I'm gonna try to advance it a little and see what happens

I once changed the fuel filter and filled the new filter full of lucas fuel treatment. Until the fuel filter was cleared of the lucas my truck did exactally the same thing! If i reved the motor up it would stall on decel. Try running down the road a stretch and getting all the power service run out of the filter. My truck was fine after fuel replaced the lucas in the filter.

Only 5 months until the rally. You can get it timed again. Hopefully it's still got life left in it, but it does sound like it's getting tired. The healthy dose of power service may have cleaned off some varnish that was helping the valve stick open somewhat.

Aric,

That's exactly what my IP was doing before it died. The extra Power Service was a short bridge to a new IP and injectors. It helped the stalling/stubling, but the weep hole was next to act up and I called it quits and got a new IP.

Heath do you still have the DPS pump and Stage 1s or is that what you had to replace?

Yes I still have my DPS IP and stage ones. It will be two year in june. I used Ken's products to replace my old IP and injectors.

Well thats been probably over a 100 miles ago already and still does it. Whats weird is after its been run a while it won't die so I thoutgh it was the heat but if you run it a while to get it hot then shut it off and then go again it will start acting up again and everythings hot I think I'm gonna try and advance the timing a hair and see what happens. I know its getting tired cause I no longer have to worry about the EGT's when towing and it used to race to 1350 with ease Its got atleast 100k on it but I was hoping to squeeze out a little more

Hmmm, Time for a Moose Pump,..?
