My 01 elantra keeps givin me a catalyst code bank 1 suggesting an air fuel mix problem.i changed the air filter but the engine light is still on. The car has lots of power but uses a lot of fuel.what is...


As your check engine light is still on I would suggest that you have a hard fault retained in ECU, also the fact that you mention catalyst bank 1, I would suggest that your fault is actually the pre catalyst O2 sensor. Some versions of scan tools can sometimes be a little vague in their explanation of the fault. If possible supply the P code that lead you to catalyst fault? as this can assist diagnosis.

My 94 Toyota Camry 4 cyl is running really rough and stalling out once the engine warms up


1. Error Code 24. Intake Air Temperature Sensor.
Solution:
Check the following:
- IAT Connector and wiring.
- Intake Air Temperature Sensor.
- Engine Coolant Temperature Sensor.
- ECM.
2. Rough Idling when the engine is hot.
The following are the reasons due to which the engine can perform bad when it is hot.
- Fuel pump control circuit.
- Fuel pump pressure.
- Fuel injectors.
- Non Return Valve clogged, located on the lower side of car chassis above the fuel tank.
- Engine compression, valve clearance, spark plugs.

Auto trans shifter shifts p-r-n-d-2-1 it wont shift out of 1st .. sat for 8 months i drove it 50 miles 5 days a week for 9 years serviced reg. never any troubles before i started it i changed oil filter...


There must have been a 'Check Engine' Light? When a 'check engine light' (MIL=Malfunction Indicator Lamp) is turned on, there is a DTC (Diagnostic Trouble Code) set/stored in the ECM/PCM (Engine Control Module/Powertrain Control Module). This code identifies which engine management system component/function experienced a malfunction. Once you pull/read this code, you may begin diagnosis. You'll need an OBDII (On-Board Diagnostics II) code reader. You should find a P07?? number stored (P07??... is a transmission code).

Underhood fuse block swap out relay #7 thats the ECM relay.
Ground Circuits Using a DVOM, touch negative voltmeter lead to a good ground. Touch positive voltmeter lead to each ground terminal. With vehicle running, voltmeter should indicate less than one volt. If reading is greater than one volt, check for open, corrosion and loose connection on ground lead. See ECM GROUND LOCATION table for ECM ground location.

I have a 99 elantra, trouble starting and now stalling


Can be many things...look at the air filter...if dirty replace it.
Dump in the gas tank a bottle of stuff to get water out...has methonal in it...in case water has condensed in the tank. When starting you might want to not stomp the gas pedal to the floor but rather push it to the floor and hold it there before and during cranking to start it....if the engine is flooding that should allow it to start but you may need to crank it 30 seconds before it catches. You can also have a weak fuel pump if it has never been changed.

What engine? Sounds like maybe timing chain jumped or it is very lean.
