Help!!!!!!!

[JHarris1385]

So I have only had my VX for a 9 days and already the CHECK ENGINE light came on. It had only been sitting in a parking lot all day while i was work. I turn it on it takes a while to fire up but does and displays the check engine light.....So i take it to AutoZone about 2 miles down the street. It drove great there but I have notice this tank of gas is getting me NO where. Im getting about 1/2 of what the previous tanks have gotten me (4) drove it back home 7 hours and went through three tanks, in one day. Although since i bought it it has taken roughly seven seconds of engine turning to finally start the engine....All I have done to the car so far is put gas treatment in the tank 3 out of the 4, and throughly washed it inside and out including power washing under the hood to wash dust away. And thats it.

Here is what was on the readout from the ODB gun;

po300 random
multiple cylinder misfire

possible cuases: ( that the young guy thought it could be)
camshaft position sensor
crankshaft position sensor
ignigition control module


PLEASE HELP, I NEED ALL opinions and whatever else you can give me. I plan on taking it to auto shop/dealership. But there is not any ISUZU ones around here at all. The guy at AutoZone did say it would be fine to drive for a bit all i would be experiecing is bad mpg.......

HELP ME out here.

Thanks,
JOHN ROBERT

I had the same issue but I just changed the spark plugs, and that seemed to do the trick. I bought the Bosch Platinum +4 spark plugs. you can check the ignition coils too to see if they are broken. check the wires and the area that plugs into the spark plug.

NOT to get away from all open sugesstions but i read that the spark pluggs are good for 100,000miles..

Try a better grade gas or even premium for the next tank or two. Driving with misfires or pinging can be extremely bad on the pistons as it creates a great deal of heat. You may have simply gotten a bad tank of gas. Yeah, they say platinum plugs will last 100k but I started changing mine every 20K or so. Some of the '00/01 VXes do not like the Plus4s and will throw a code.

Try looking at issues related to "power washing under the hood".
