So the new pcm showed up yesterday. And after program it started. Right up no problem.
I drove it today on highway and it seams to do the job. Although I'm getting a check engine light.does any one have ideas????
Please help

Umm scan it and see what the code is....just an idea lol

Yes I'll. Have to stop over at autozone do see what they say. Just wondering if this has happened before... thanks for you. .02

No problem.Sorry if i sounded crude.didnt mean to.get back to us with your findings on that code and maybe it may be related to the tune but it could also be coincidental.O something coverd up by a previous tune..

That makes a bit of since as far as covered up from previous tune. I'm at work till close so autozone is out of the question till tomorrow. But I will be updating.

nothing I did on the tune should have tripped a light. Post up what you have.

I will be on this ASAP in the morning I'm running over to autozone. They are across the street from my house.. thanks guys

Drum roll please..... p0420 is the code and if I'm not mistaken. That'* 02 sensor. Now I no that that was turned off during this tune. And I don't think this is effecting the runability. If the hi Flo cat does not have use for the o2 should it be unplug?

That code is labeled as catalyst low efficiency, Looks like I missed that code. Plugging the sensor back in will take care of that.

But there is no place for it to go in the cat now. Do you mean just plug it in and leave it secured to something or do I need to drill out something.
