Whats a good spark for a 2004 chevy silverado 4.8 with 115500 miles

What's missing ? Fuel ,spark , compression ? How many miles on the vehicle ? Does it have spark , pull a plug wire while cranking an hold it near a good ground . Put a fuel pressure gauge on the vehicle , is there fuel pressure ? Do a compression test , 150 psi . engine mechanical problem . timing chain .

It shouldn't. The TPS sensor is voltage based on throttle position. If the plugs are bad, you should get a separate cylinder misfire code only. If you are getting a TPS code, it is likely the TPS. Remember too, it is an electronic TPS, so there is a sensor on the accelerator pedal assembly that it talks to. Make sure that's plugged in. What you can do is with the vehicle in the on position (not running) - push the pedal all the way to the floor a few times. Also, clean out the throttle body and ensure there is no gunk preventing the throttle body from opening smoothly and all the way. Good Luck.

with a 5/8 inch spark plug socket and a rachet. simply pull the wire off of the plug, change the plug , then push the wire back onto the plug.

Hello: You will have to replace the cluster.After replacement the cluster will need programing, mileage and engine hours set.

If you have a lot of miles on it your 4wd trans.

Not if it is running good and you get good gas mileage

Hope helps (remember to rate and comment this).

try selecting from nutreul or less then 3km

that depends on the miles on the truck. spark plugs every 100,000 miles, other ignition parts inspect and replace as ness, fuel and air filter every 30,000 miles. all belts and hoses should be inspected as part of any service.

The stepping motors in the gauges go bad. do a search on ebay for CHEVY SILVERADO INSTRUMENT CLUSTER for cheaper repair options. The dealer charges around $300.00. It will continue to worsen.
