Replace the coil packs.
Your issue is NOT the converter, or you would have a P0420/P0430 code

a/f sensor circuit range/performance malfunction bank one sensor one system to lean bank one how do i fix
P0171- mens the MAF sensor is dirty and needs cleaned. You can get MAF cleaner at your local auto parts store. The MAF is located in the air intake just after the air filter
P1130- is more than likely a result of the previous code. It is in regard to the feul/air mixture ratio. A dirty MAF can cause this code.
Also, if you are using an aftermarket oiled air filter, it would be the cause of the P0171 code.

I need to replace the oxygen sensor on an 2001 Toyota Tacoma 4WD regular cab pickup. It is the 2.7 liter 4 cylinder engine. I need to know the location of the sensor and if this is something I can do on my own with basic hand tools. The truck computer showed a code 1630 or something like that. The computer check showed that this meant the oxygen sensor was going bad. I was told it would cost approx. $300 dollars to get it fixed. I have the money, but if it is easy and I can save money, I would rather fix it myself. Any help would be appreciated. Thanks!
REMOVAL & INSTALLATION Start the engine and allow it to reach normal operating temperature, then turn the ignition switch OFF. Disconnect the negative battery cable. Open the hood and locate the O2sensor connector. It may be necessary to raise and safely support the vehicle for access to the sensor and its connector. NOTE: On a few models, it may be necessary to remove the passenger seat and lift the carpeting in order to access the connector for a downstream O2sensor. Disengage the O2sensor pigtail connector from the vehicle harness connector. NOTE: There are generally 2 methods used to mount an O2sensor in the exhaust system. Either the O2sensor is threaded directly into the exhaust component (screw-in type) or the O2sensor is retained by a flange and 2 nuts or bolts (flange type). WARNING To prevent damaging a screw-in type O2sensor, if excessive force is needed to remove the sensor lubricate it with penetrating oil prior to removal. Also, be sure to protect the tip of the sensor; O2sensor tips are very sensitive and may be easily damaged if allowed to strike or come in contact with other objects. Remove the sensor, as follows: Screw-in type sensors: Since O2sensors are usually designed with a permanently-attached wiring pigtail, it may be necessary to use a socket or wrench that is designed specifically for this purpose. Before purchasing such a socket, be sure that you can't save some money by using a box end wrench for sensor removal. Flange type sensors: Loosen the hold-down nuts or bolts and pull the sensor out of the exhaust component. Be sure to remove and discard the old sensor gasket, if equipped. You will need a new gasket for installation. Perform a visual inspection of the sensor. Black sooty deposits may indicate a rich air/fuel mixture, brown deposits may indicate an oil consumption problem, and white gritty deposits may indicate an internal coolant leak. All of these conditions can destroy a new sensor if not corrected before installation. To install: Install the sensor, as follows: NOTE: A special anti-seize compound is used on most screw-in type O2sensor threads, and is designed to ease O2sensor removal. New sensors usually have the compound already applied to the threads. However, if installing the old O2sensor or the new sensor did not come with compound, apply a thin coating of electrically conductive anti-seize compound to the sensor threads. WARNING Be sure to prevent any of the anti-seize compound from coming in contact with the O2sensor tip. Also, take precautions to protect the sensor tip from physical damage during installation. Screw-in type sensors: Install the sensor in the mounting boss, then tighten it securely. Flange type sensors: Position a new sensor gasket on the exhaust component and insert the sensor. Tighten the hold-down fasteners securely and evenly. Reattach the sensor pigtail connector to the vehicle harness connector. Lower the vehicle. Connect the negative battery cable. Start the engine and ensure no Diagnostic Trouble Codes (DTC's) are set. Posting pictures next......

need wire diagram for 2001 toyota tacoma for installing JVC kw-nt3hdt stereo or any advice
Hi, here are your factory wire colors/functions. Aftermarket stereos have a common set of colors, which should be in your installation diagram. The process is simplified if you purchase a wiring adapter for your vehicle. These are available for under $10 at most WALMARTs and auto parts stores or about any place that sells car stereos. In either case, I recommend you solder the connections or at least use crimp terminals. If you have any more questions, please let me know--I've done a lot of stereo installations.

OK. First off. I took my 2001 Toyota Tacoma (Manual, 2.4L, 2 wheel drive) into the shop because it would miss fire at idle and would hesitate a bunch when I would try to accelerate quickly. The auto shop replaced spark plugs, ignition coils, cleaned throttle body. Had a PO100 MAF Circuit fault Code and a PO110 Intake Air Temperature (IAT) Sensor 1 Circuit code. Got it back. Truck ran a bit better but was still miss firing at idle and was still stumbling a bit on quick acceleration. Took it back to the shop. They then changed the fuel filter. They also then changed the radiator because I had a leak in it. After they did this they then said they had a problem with the truck stalling immediately upon start up. They kept for about 2 weeks trying to figure out the problem. They changed the Cam Sensor and the Crank Sensor. They said it was starting again even though it still miss fires a bit at idle and still hesitates on quick acceleration. Drove my truck about 3 days then Friday morning had trouble with the truck stalling on start up. After about 20 tries it finally started and I drove it back to the shop (3rd time now) and told them it was stalling on start up. So they kept it for another week. Called me a week later stating that it seemed to be starting fine and to bring it back if I have any problems again. So I picked it up again. Drove it for about 3 days again. The next Friday morning it stalls again on start up. Only this time it will not start. It cranks and starts for about a second or 2 then dies. Haven't been able to get it started yet. Have spent about $1300 at this point and it still miss fires during idle, still having problems accelerating and now it stalls immediately on start up which is a problem I didn't have before I took it into the shop the first time. Any ideas?
Check the battery cables. I had the same issues with my 96 tacoma, The battery cable connection at the battery can be cranked down but still be loose. Hard to explain, doesn't make sense, but just check it out.
