SLOW THROTTLE RESPONSE
2003 Chevrolet Silverado • 186,000 miles
When i first start my truck my throttle is very hesitant, and my truck feels like it has no power at all. if i let it idle after trying to run it, it feels like its gonna die. it almost sounds like it is cammed. I have changed my PCV valve cleaned my air intake and throttle body. i either think it is my o2 sensors or my coil pack. please share your info with me.
Use a gage and check for proper fuel pressure fuel pressure. Can you check for applicable trouble codes? Some of the national brand autostores will check codes for free.
I forgot to ask litre size of engine?
It's a 5.3 v8, I took to autozone and they said it was the MAF, I changed it and it is still doing that. The check engine light flashes when I press on the gas.
What was the actual code number? The code doesn't tell you what to replace, just that the system thinks there is a problem on that circuit, somewhere.
