Hi, I have a 1998 Camry with a 2.2L. It is having intermittent power loss, Not all the time, just a few time while driving. I can manage to clear it out by revving the engine. Timing is ok, I replaced coils and wires, a while ago.
The check engine light come on occasionally, but dose not stay on all the time. It feels like fuel or exhaust.

Thanks for any help.

 

Check light on means a trouble code(s) has been stored. The easiest method is to download any trouble codes.

 

I agree with Joey. If you don't have an OBD II scanner, go to your local auto parts store, most will scan your system for free.

 

i have same problem but it seems worse when i drive it runs good while parked but acts up when i put in gear i did have mine diagnosed gave me 4 codes IAT, MAF, knock sensor bank 1@2 was told it could be one of those things but not sure

 

The codes are po172, and p1130, there is no MAF on this car. I am going to start with a good cleaning, and see what happens. Then replace OX sensor.

 

P0172 is fuel trim rich meaning mixture is too lean.
P0130 is Bank 1 Sensor 1 02 sensor.

Also check for exhaust leaks.
Fuel pressure.
MAP sensor-seldom fails.
Engine coolant temp sensor for computer.

If changing 02 sensor use Toyota or Denso brand. If Denso use one specific to car, not a universal type. Note California and Federal emissions cars may use a different sensor. If different, get the one for your cars emission system.
