SOURCE: small evap leak

The evap leak is short for EVARORATIVE EMISSIONS SYSTEM, NOT AC EVAPORATOR, AC leaks do not cause the truck to fail emission, most likely the problem is a defective gas cap. Also the code you give (P0244) is a watse gate code, please provide the correct code.

Check all of your EVAP lines and the charcoal canister. Also check the lines and overflow line from the gas cap to the gas tank.

SOURCE: Car won't pass inspection due to catalyst and O2 senser not ready

O2 not ready could be that the sensor is not warm enough due to the engine not being warmed up, or the sensor's heating element not working. This would cause a richer air/fuel mixture showing a catalyst problem. If you are over 60,000 miles or so, it could be the O2 sensor, but you need to have it diagnosed before replacing the wrong part. Possibilities include a bad, fouled, or damaged sensor. The wiring could also be damaged by contact with road debris or the exhaust pipe. Leaking injectors can also produce a very rich mixture, but a good O2 sensor should be able to detect this and set a code. High oxygen content in the exhaust means unburned fuel because in combustion, the oxygen is used up. Good combustion leaves low oxygen in the exhaust. The oxygen sensor measures the oxygen content and lets the processor adjust the air/fuel ratio according to this reading and that of other sensors such as throttle position, mass air flow, coolant temperature, and ambient air temperature. The codes received at the inspection are basically the same ones used to diagnose the problem. There are dealer specific codes also used for repair. I really hope this helps. Please let me know if you need any more help. Thanks

SOURCE: Having the same problem the other guy described.

First of all, these codes are what are called "Powertrain Trouble Codes' (that's what the "P" means P=Powertrain). TCM Request (Transmission Control Module = TCM). The request was to turn on the 'Check Engine" light.
P0720 - output speed sensor circuit malfunction
P0715 - Input speed sensor (turbin speed) circuit malfunction
P0442 - Evaporative Emission System Leak (Small Leak)
P0455 - Evaporative Emission System Leak (Large Leak)
Check fuel filler cap problems - for Evap Emiss leaks
Replace the pulse generators & have the trans fluid replaced/flushed.
The Main Catalyst System Efficiency Bank 1 Is P0420, not P0442
If you had P0420 code, the catalytic converter is shot... and that's an expensive component.

Take it to a muffler shop-that mechanic must have a tin ear. I thought my Sentra had a small exhaust leak (slightly loud exhaust noise) from a previously fixed exhaust connection. But a muffler shop guy showed me I had a rusted out catalytic converter. I would suspect your flex pipe may still be leaking.

No power. Runs better the less gas you give it. It is the wordt when the check engine light flashes

sounds like your car has gone in to limp mode you need to go to a garage and have a diagnostic test

The O2 sensor was changed last month. The check engine light returned. The dealer said there was a leak in the flex pipe. Recommend replace flex pipe. Did that. problem still exist. When driving the car...

Replacing an O2 sensor generally is "fixing the symptom" instead of fixing the cause. A good O2 sensor will often trigger a code if the exhaust mixture it is "seeing" is out of its range to adjust. If the pipe was bad when the sensor was changed, or if another part of the engine management system is out of range, it can cause the new sensor to fail or trigger the check engine light. In your case, I'd clear the codes and see if that helps. If not, you likely will need to do better diagnosis and perhaps again change the sensor if everything else checks out as good.

Still loud

Have you checked the flex pipe section under the engine, and the gasket between the manifold and cat/flex pipe section? Those are two places they usually start to leak from either a blown gasket, or the flex section rusts out under the protective covering.

Start the car open the hood. with the hood open listen and smell for the leak. Probably the frt exhaust manifold leaking. Independent mechanic can repair just as easy. No need for dealer. If the leak is bad enough you will smell exhause leak. Look for the area with the greatest amount of noise.

Exhaust leak near drivers side door

This is a flex pipe and VERY expensive to purchase from the dealership("Y" pipe). Just go to midas or the local mechanic and have them use a universal joint. Won last as long and may crack later leaving you with exhaust noise, but nothing more depending on the size of the crack.
Mine is hanging in there since March 08...
