my truck was boggong th same way in the upper rpms. a fuel pump did the trick for me.

 

To clean your injectors, go to walmart and buy some Barrymans B-12 Chemtool in the aerosol or a regular can. After you get the fuel rails/injectors out then remove the injectors from the fuel rail by popping off the c-clip. pour or spray the b-12 inside them and let them sit for a few minutes, then blow it all out with an air hose but dont get that **** in ur eyes. Then pour/spray some on a rag and clean the tips. Have you ever pulled out the injectors? Do you have a Chilton manual or the like? Make sure you relieve the fuel pressure before you start and lube all the o-rings before everything goes back together.

That is a cheaper alternative compared to replacing the fuel pressure regulator($75) or a fuel pump($150+). And after you get everything back together put some of that b-12 in your gas tank I think it is 8oz.

 

May be your injectors!!!!!!!!
Does it have a rough idle?
If it does have the rough idle, since you are from deer park Texas you can take it to a mr carwash that has the oil change bays and ask them to do fuel injector cleaner and to clean out your throttle body. But it has to be the cleaner that is injected through the versa valve (I think that is what is called) on the fuel rail. Costs about $70 bucks for everything. If it still has the problem, then you can be sure it is not the injectors. This helped my 2001 Yukon a great deal. Mileage wise and performance.

 

Sorry!!!!!!!
When this is being done to your truck you can actually see the soot and smoke that comes out of your tail pipe. Especially the first time.

 

It was the fuel filter, runs good as new now, thanks for the advice. Cats going off this weekend
