I have a 97 corvette , the check engine light was on so I took to dealership, they replace 3 oxygen sensors, picked up the light came back on. At a lost end. These are the codes...

You can look up the error codes on
Because the error codes indicate heater circuit failure.
P0135 and P0155 mean the heater circuits for the front oxygen sensors are not working properly. You need to check the fuse.
#15 under the hood I think.
If that is OK, make sure the exhaust system is grounded. I believe the ground strap is on the back of the cylinder head - right side.

It would be rare that both O2 sensors died again, that quickly. I suspect the dealer didn't really do any diagnostics and just replaced parts (cheap option at least for them).

Fords are notorious for bad vacuum lines. Mostly the elbows that are preformed. These just don't stand up to oil or any chemical. These are located any place on the plenum. Some are on the bottom. Hard to get to, but not impossible. Usually the are the large ones that go bad first. Look for the vacuum line s and follow them back to the intake plenum. Sorry you had to replace the MAF...The O2 codes are from the ECM trying to compensate for the extra air coming in...

99 expedition odometer goes off & on randomly

Take the instrument cluster out of the truck. Turn it face down and remove the back cover. It is a big computer panel. Right behind the odometer screen you will see nine little wires coming up and saughtered to the board. One of the wires will have a crack in the saughter. It needs to be redone to make a good connection. I had this problem for a long time and it took no time to fix. Hope this helps!

P0151 code is from a low voltage from the oxygen sensor circuit. P0300 code is a result from an engine misfire in one of the cylinders. The 4WD in the information center and the two Error Codes sound like an electrical problem.
