P0137 is an O2 sensor low voltage code. bank 1 sensor 2. This could cause a rough start. The sensor that needs replaced is on the drivers side, after the catalytic converter

Yes its possible that fuel pressure is getting low or fuel filter is getting clogged or the O2 sensors are getting hot, O2 sensors when get weak, they get hot and loose communication with cars computer and due to that car stops controlling fuel and this can be problem.Also there are other possibilities like, faulty or dirty, IAC valve or dirty throttle body.Getting all this possibilities inspected, checked will point towards the cause of problem.--------- This should help.Thanks.Helpmech.

SOURCE: at start up,engine makes clonk noise ,second it starts,

The clunking is most likely the starter/flywheel issue. Loose starter, starter or started bendix damaged or flywheel cracked. The P0137 is a post O2 sensor voltage low. If the sensor has not been changed, probably the sensor has failed.

SOURCE: 1999 silverado,4.8,v8,1500,code PO137

That particular DTC is most likely unrelated to your driveability concern. The P0137 refers to a catalyst monitoring oxygen sensor problem. This DTC will not noticeably affect the way the engine runs. Does it have a P0171 and/or P0174 DTC stored? With this concern on this engine management system, I suspect a vacuum leak after the Mass Air Flow (MAF) sensor, a dirty MAF, A faulty/dirty Manifold Absolute Pressure (MAP) sensor, a ruptured fuel pressure regulator, or low fuel pressure. If it runs basically normal when the engine is warm, it is almost for sure not directly related to an oxygen sensor. If you have other Diagnostic Trouble Codes, address them first.

2001 Chevy Silverado 1500 4.3L V6 was running fine and then the O2 Sensors went out. I have since replaced them but it with start then idle really rough then die if you let off the gas

Robert, have vehicle scanned for diagnostic codes. Check for vacuum leaks and if you have not done recently give vehicle a complete tune up cap,rottor,wires,plugs,filter's,etc, including injector/throttle body cleaning. Check the attached links,instruction and guides, Good luck

2004 chevy can spark plugs cause scanner to read tps on a 6.0 l gas 2004 chevy silverado

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.

2000 silverado 4.3 V6. Replaced feul pump and niw it starts but it takes 3-4 cranks in the morn to start it and then it runs very rough untill it has ran for 1/2 to 1 hr. Also have replace fuel filter...

The rough running should have caused the check engine light to come on. It would be a good idea to goa ahead and scan the engine for trouble codes. The rough running could be a number of things. The codes would help us pinpoint the correct part ot replace, rather than start replacing parts until we get lucky and hit the right one. That could be very expensive.

99 chevy silverado 4x4 getting code p0304 coad changed plugs wires and coil still getting code, runs rough and cranks for a long time before it starts

You could have a faulty Fuel injector problem with your poppet valve. There common to go bad and start to leak causing misfires and ruff idle. There is an upgrade to the CSFI to covert to MFI system.

Here is a link that should help you with your P0304:

2003 Silverado rough idle, idles good after "check engine" light

Check your o2 sensor voltage, those trucks are real bad for o2 sensors, and yes if one sensor is reading 0mv, the others will start to drop out, and the vehicle will run very, rough. You also may check fuel system pressure, should be almost 60p.s.i. If its alot lower, Id be looking into a fuel pump. If that vehicle is drive-by-wire (no throttle cable), the throttle bodies get very dirty and cause that concern also. Id start by having the vehicle scantested.

I have experienced this problem on similar vehicles. You should try and replace the coolant temp sensor. If it is not reading the correct temp to the ecm, it will not get the right fuel map. Also, the cts will not always throw a code.
