#49 of 151 Rough Idle, stall, and missfire during cold temps.
Jan 21, 2009 (4:19 pm)
2002 Chevrolet Silverado 1500 4x4 Z71 5.3 Vortec
Engine. 109000 miles. Only on cold mornings/days
does it stall and idle really rough and missfire. Here is the strange part: if I unplug the MAF sensor, it runs
fine. If I plug it back in, goes right back to crap. So I
thought i had found my problem and replaced the MAF Sensor but to my surprise it did the same exact thing. It is throwing a coolant temp sensor code so maybe
that is the culprit. My question is if it is a bad coolant temp sensor, why does it run fine when I unhook the MAF? I also tried unplugging the coolant temp sensor but it still does the same thing if the MAF is plugged up.

Hi, I am looking for advice on my truck. I went out and cranked it for work this morning and it was a real hard start. I let it warm up and when I went back out to leave I started having problems. Right when I put it in drive and gave it gas, it stuttered /cut out and what sounded like valves clattering could be heard. Every time I got on the gas good it just cuts out and makes that sound. I tried it again later and it didn't cut out as much only when I really got on the gas hard it did, but first thing this morning it was doing it when I barely gave it gas.
It feels like a fuel issue, maybe the fuel/air mixture issue or I am beginining to wonder if could be my timing chain?
Any help is appreciate.

Did you ever find the cause?

It sounds to me your truck is stalling during turns. Check out my post #47 and follow the simple directions. Let me know how this works for you.

my truck had the same problem.. the brake vacuum booster was leaking and messing up the vacuum for the engine.. unplugg the hose to the brake booster and plug it and step on the gas see if it helps. if the motor doesnt' cut out or sputter when you hit the gas its the booster.

I´m new to this forum and I am writing on behalf of my father who owns a Chevy 1500 Silverado with a 6,5 litre V8 diesel engine. This is his pride and joy...but unfortunately he is having major problems with it.
The truck is, for lack of a better word, quite moody. It will occasionally start ok and run with no problems whatsoever - no stuttering or other problems, and then suddenly stall and die. It can be really hard to get it started after this has happened. Now...I´m no mechanic but I will try to relay and translate what he has done with the truck so far:
-Fuelfilter is replaced
-Fuelpump attached just beside the tank is also replaced
-Tube/pipe inside tank (suction-pipe?) is also replaced.
Battery is quite good and not yet a year old.
Outside temperature or humidity doesn´t seem to be an issue (damp weather and so on). Strange thing is that the truck stalls/dies without warning....no spluttering or misfiring etc.
My father suspects an electronic fault...and before we go to see the mechanics I would like to hear any advice you can offer.
I´m thankful for any input that could get my fathers beloved truck up and running again...

I suppose my father needs to take it to a garage somwhere...just to get it checked.
I have read a lot of forumposts but almost everyone with stalling problems seems to have a spluttering, misfiring truck or electrical trouble. This one just dies...completely ..in one go. Not so much as a hiccup even...
I guess troubleshooting by professionals is the next step.
Did you find out whats wrong with your truck then?
