There is an OBDii code reader available on ebay for $10. Get the one with the lights and there is blutooth model that can download app for your phone. Other than that you be guessing and changing parts.Try running a new ground wire from the neg side of battery to the body and to the engine and check wiring, sounds electrical. I beleive the ECM is located inside the front part of the fender on passenger side and it's exposed to the elements, be good to check this for corroded wires and connector as well it the harness may be rubbing up against the body in that location and shorting out. Look for lumps in the harness at the point it connects to the ECM again should be located in the front innner wheel well behind the headlights but you will need to get to it from underneath or remove the inner plastic fender. Some newer models the ecm is on top of the engine and check the harness where it runs along the body as it may be moving and baring wires at that location or some wires may have corrosion and bad connection.

Hi, I'd focus just on that cylinder for now, unless the other lights come on again. This ought to give you enough information to start diagnosing the problem - http://www.obd-codes.com/p0301 - good luck!

Sounds like you have a bad wheel speed sensor. You need to have it scanned. Since it's been sitting, it might just be a bad connection to one of the speed sensors.

I have had exactly the same problem on and off for 3 years now - and just solved it last week thanks to another computer site. Remove and disassemble both grounds from the top of both the left and right frame rails adjacent to the front corners of the engine block. Completely clean the green corrosion from the internal parts with fine sandpaper and add dielectric grease then re-assemble. Clean the mounting bolt and frame hole while you're at it. Sounds time consuming and difficult, but it ain't. No more than 45 minutes combined. I am a technical airhead so if I can do it so can you. What clued me in was the problem always occurred around wet or humid weather. Also, the clock would always lose time overnite. That has ceased also. Good luck. Anyone know why my left headlite, when deployed, vibrates and shimmys??? Sully [email protected]

The ABS sensor is a speed sensor also for Traction Control. This is why both lights are on , One of your front ABS sensors are bad or disconnected, or has a pinched wire.

you've got a bad wheel speed sensor or corresponding tone ring. take it to a dealer. they'll hook it up to a computer and tell you which sensor or tone ring it is and give you an estimate. you only pay for the hour of diag.
