Check Engine Light, runs rough, no code!
2000 3.3L
The CEL comes on as soon as I start the engine. The idle is rough, but I don't see any change in RPM. With acceleration or under any load (even at constant speed on cruise control), the CEL starts flashing. Three different meters at two different places failed to get a code. With all three meters, the meter reads "WORKING," but no code is produced, even after several minutes, engine running or not (but, since it's idling, the CEL isn't flashing).
Would it help to run the car with the meter to get a code? I've cleaned the mass flow sensor.
Any ideas?
Follow up
I learned that many readers won't get a code if there's any accessory plugged into the cigarette lighter.

Problem solved
Found a different brand of OBD reader and it indicated the knock sensor and a cylinder misfire. Replaced the plug wires and it's running fine.
Knock Sensor
Knock Sensor will NOT throw a code, try this, figure out where it is, Disconnect it and see if it makes a difference, or throws a code, if it does throw a knock sensor code u will know it is working, if after removing the harness it still doesnot throw a code its KS.
knock sensor
Thanks! I'll certainly check it out. I was under the impression that the knock sensor was more of a "symptom indicator," only there to send a code signal in the event of a knock or misfire. But, I didn't think a bad knock sensor, itself, could cause these symptoms.
