Tahoe 4x4 125k mi., intermittently die's at low speed cornering or acc from a stop.
Starts right back up. Replaced plugs and wires @100k, fuel filter also. Luckily
ran fine during last weeks sleet and ice. Now back to acting up. I'm thinking fuel pressure, but like I said it's intermittent. Any idea's? Thanks
First new vehicle we ever ordered, and intend to keep another 125k mi.
98 5.7 350 vortec 4x4

 

I'd consider having the fuel system serviced if you have not had that done, an easy way to find out if that is the issue is run a couple or three bottles of injector cleaner thru a full tank and see if it improves..

 

Recommend using Techron. Others like Seafoam.

 

Not to be a smart @#*, but did the easy and obvious already, to no avail., Thanks

 

We can't assume the obvious in the forum...well because its not always obvious...
I'd try checking the EGR valve it could be sticking,
check electrical connections to and from battery especially grounds

 

did you ever get a fix for this problem, i have an 07 that is doing the same thing.

 

Your 07 Tahoe is stalling at low speeds?

 

Yes not all the time. It is very sparatic. Right now it does it maybe once a week.

 

And no codes are setting? How many miles do you have on her?
I'd check the fuel pressure to start off with its easy enough to get to...

 

I decided to go ahead and take it to the Chevy dealer. They told me yesterday that it needed a new throttle body. It has 62000 miles on it, and there was one code P2119 I believe.
