My truck has minimal to almost no power. the engine starts up but shows alot of hesitation. i changed all the spark plugs, fuel filter, egr valve, 02 sensors and even got a tune up. still the same problem. i also had the gm licensed computer hooked up to find out the problem. error codes are as follows, p0300, p0576 , p1404, p0135, p0101. i am not savy with automechanics so any help would be awesome.

If there are a lot of miles on the truck I would check compression. It sounds like you have done a lot of work and covered all the bases of lost power. It could also be a fuel regulatory problem, possibly "filter, pump, valve on the fuel rail" If it has been sitting for awhile it could be the fuel. Hope that helps!

Intermitently quiting at idle. also ocassionally surges when accelerating. happens more frequently when ac is on.


There to many reason why if you have an Idle problem. Here are some example.
1. You may have a vaccume leak.
2. misfiring (spark plug)
3. Sensors on the engine 02 or EGR valve sensor.or EGR valve.
4. manifold Intake leak
5. cloged trottle
6. coil or relay fuses.
7. fuel filter or fuel pump ( I hope is not the fuel pump) lol.
My best BET is use a high power clean GASOLINE for tree days and see if your Idle problem change, and if there is no change, GO to Autozone or any car parts dealers and kindly ask them to borrow there scanner to diagnose your car. Good Luck. Reginskie. :-)

Perform a valve clearance inspection and adjust if necessary. Tight or sticking valves will cause a misfire or rough running concern. Note: Perform valve adjustment when the engine is stone cold. 4cyl: INT 0.26mm EXH: 0.30mm (V6 engine are hydraulic and no adjust necessary.) Also check for a sticking or stuck open EGR valve. For diagnostic purposes only: Remove the EGR valve. Place a business card over the EGR passage and bolt the EGR valve back on. This plugs the EGR ports and if the misfire goes away the EGR valve is partially stuck open and is defective.
Check for low fuel pressure. Check for low compression. Check cam timing. Check for a weak ignition coil. Also don't over look the possibility of worn or broken engine mounts which cause excessive engine movement and engine vibration. -hope this helps

You replace alot of things but you should replace the EGR valve and the throttle positioning valve also. I would start with the EGR valve

Check your fuel filter and air filter. That is usually where your hesitation starts.
