Check compression in number three. You could have bought a bad engine. And yes. You need to change every sensor. If they don't match with the plugs. replace the engine. There is a reason for different engine codes. You should have stuck with them.

2003 Tahoe Running rough, Idle irratic, Ck engine light on. I put it on a OBD2 code reader and showed p0101 mass airflow sensor and bank 1 and 2 running lean I cleaned the sensor but still having problem...


Yes, replace the MAF, then check if the lean condition goes away. It should.

MAF's are sensitive to cleaning. Sometimes it works, other times it doesn't.

Escort has engine light on, diagnostics say 02 sensor is out, both were replaced, same code for 02 sensor bad shows up, replaced again, same code shows up


MOST OF THE TIME AN 02 CODE DOES NOT MEAN REPLACE 02 SENSOR..SOME AUTO PARTS STORES WILL SCAN YOUR CAR..TELL YOU CODE 02 SO PEOPLE AUTOMATICALLY REPLACE SENSORS...IF YOU CLEAR THE CODES DOES THE CHECK ENGINE LIGHT COME BACK ON RIGHT AWAY OR DOES IT TAKE A LITTLE TIME... IF IT TAKES A LITTLE TIME THEN YOU HAVE SOME PROBLEMS THAT ARE CAUSING THE EMMISSIONS TO BE OUT OF RANGE.. IF THE LIGHT COMES BACK ON RIGHT AWAY YOU HAVE A PROBLEM IN WIRING HARNESS BETWEEN THE SENSOR AND ECM....MAIN COMPUTER.....OR SECONDLY POSSIBLE PROB IN THE MAIN COMPUTER...GET SOME OF THOSE ANSWERS AND FIND THE EXACT CODE THAT RETURNS THEN GET BACK WITH ME FOR MORE HELP

2001 Tahoe: Hard to start, idles rough, check engine light on.


Flashing check engine light is missfire, fuel pump probably causing multiple tries to start.Having to build fuel preasure,vac leak on one side of intake probably causing rich/lean condition.Also check back preasure to cat ,Sound like you are moving down right track.Mas air flow would probably set lean code bank1 and lean code bank2

P0135 is a bad 02 sensor
P0442 is a evap problem
P0449 is a vent solenoid

i would check the vent solenoid first its a 4ws fuse under the hood in the fuse box make sure you have power to it you should have power at all times the ground comes from the pcm i think if you fix this everything else will work they are all computer controled

Engine runs rough at certain speeds 3.0 v6 flex-fuel 1999 ranger


Check and see if the EGR valve is leaking, to check this spray water on it at idle, if the water steams off the valve is leaking and is the source of your problem, also are you sure you hooked the new DPFE sensor up right? re-check it..
