P1137 relates to a blip in the fuel trim where as the max threshold was reached. I have simply deleted the code in the past and it was ok, never came back. However if it does come back you will need to find the cause. This is most likely a MAP or MAFS fault.

Its your oxygen sensor. But some car's has more than one. Could be on bunk 1 side or bunk 2. Usually, codes will tell you like p1137 then definition. Bunk 1 means before the catalytic converter, bunk 2 means after. All car manufacturer has different location on this sensors defending on engine size. Good luck.

Need to reset the check engine light

This is for the 16 pin diag
With obd-2 or home made code reader retrieve codes. After each code press and hold the button on the tester for 6-8 sec. then retrieve next code. After code is received press and hold for 6-8 seconds. Continue until code reader flashes only 1 time. Do this for slot 3, 8 and 14. Once all sections return a single flash code indicating no malfunction, turn ignition off. Next time you start the vehicle the light should be off. If still on, check for codes! If new codes perform repairs!

Idles rough and low intermittently. Stalls occaisionally. Error code P1137 pulled off of the computer. 2001 Alero, 2.4L Automatic trans

P1137 is HO2S Bank 1 Sensor 2 Lean Or Low Voltage. Oxygen sensor is reading a "lean condition". This code probably is stored from the rough and low idling. So it sounds like you maybe having other issues causing this P1137 code to come up. For lean conditions read this:
1. Vacuum leaks - check for failed or loose vacuum lines, leaking intake gaskets, intake air tubes loose or any other source of un-metered air leaks (leaks after the Mass Air Flow Sensor)
2. Restricted fuel filter or bent/pinched fuel system lines
3. Incorrect input from other sensors, such as the Mass Air Flow Sensor/cam or crank sensors, which may not always drop a separate code
4. Engine misfire ? Yes I know this one may seem weird. You might think that if there is a misfire then you will have all that unburned fuel and it should read rich; right? Well the O2 sensors read only oxygen content in the exhaust, so if you have all that unburned fuel from incomplete combustion then, you guessed it, you also have all that unburned oxygen. High O2 content in exhaust equals a lean reading!

Service engine light comes on , what kind of scaner is needed

you can use a standard scanner with a adapter or you need a paperclip. You find the diag connector under the driver dash board. If you put the paper clip from A to B and turn the ignotion on (dont start the car) and watch the check engine light. The light will blink a code three times and then move to the next code if there is any. It will blink like so for example if the code is 12 it will blink once pause then blink twice and repeat three times. It will then display any other codes. Remember that it will show each code three times before moving to the next code. You can research the codes online, at any autozone or post them here and I will tell you what the meanings are and try to give you a course of action to follow.

It is at 161,000 miles and check engine light is on

You need to have computer diag. done, some parts places like autozone will do a free code reading for you, the check engine light means that your computer pick up a bad signal from one of your engine sensor's, get the code and get back with us here at FixYa so we can help you diag your trouble code.

Getting code P1022 when checking onboard diag. chek engine light also on intermitt 03 jeep wrangler 6 cyl 4X4

that is an injector problem.injector # 2 is letting out a high output.this could be there is a bad connector or a damaged wire.this will affect the way your injector reacts and will cause the check engine to go on and would need an injector tester to check the spray pattern for your injector.

Diagnostic Connector has no power to get a code.

check the fuse for the cigarette lighter. it is the same circuit as the diag. port power.
replace fuse if failed and check codes.
