It is an 03 silverado with about 80,000 miles. It will barely go 40 and takes it a 1/4 mile to get there. What in the heck is wrong with it??

 

Reduce Engine Power???

 

what is the problem? does it not turn the rpms or not shift out of 1st or what?

this could be a metric ****-ton of different problems or a combination of several.

does it make any odd noises? maybe a vid could help

some body pull the spark plug wires off of one bank?

 

Well it has some vibration. It does shift out of 1st. but when you press it to the floor it just will not go. The check engine light is blinking too??

 

your convertors are clogged or the fuel filter is stopped up...

 

fuel filter is new! I changed it not long ago!! Oh and the truck dies too

 

maybe check your connections when you changed it out. maybe you overlooked something. it could be something minor. if it dies, hesitating, and so forth it sounds like its not getting any fuel.

 

that means something specific, but i just cant think of what it is right now!

do you have any way to scan it for SES codes?

 

Well It has been doing the dying b4 I changed it!! I don't have a OBDII scanner i can get to today. It just started doing this like today were it would not go

 

you are going to need a scanner to pull whatever code it is throwing
