I am new to the battle with the Tune Port. I just finished the install and got it running. Set the timing at 6. Set IAC and TPS. All that good stuff. Went on a drive for about 15 miles. Jeep ran fine. On the way back it went to 250 it was night time and I had some fine glowing headers? What is up why would it run so well then head south?
I checked the timing and it is working. It is advacning the timing with the motor???? Need some help on this. I had my computer custom burned, any ideas. Thanks

 

If your headers were glowing, you were running extremely lean.

 

Paul,
That is what I thought. But someone else told me that I could be running extremely righ also?

 

You could be running way way to retarded as well, check and make sure your EST wire is hooked up.

 

Tpi -Iroc,
I checked my timing it is around 8 deg. then when I hook the computer up it take iver and ups the timing. I think that is ok

 

when i first put a new motor and headers in my car it ran that hot, until i re-installed my airdam.

 

Paul or Any other help,
I called my computer guy. I have my timing at 8 deg. He said to try and set my timing up a little more. Although I already have it at 8. Surely shouldnt need it to go any higher. SO....

I had to use some gasket maker at the collectors..... Will a very small leak cause O2 reading to become distorted.

Also when I ran my fuel line I used a Fuel repair kit I bent the tube and it creased a little. would this cause poor fuel pressure? I woulnt think that it could harm it that much.

Thanks alot guys for the help!

 

There is a place on the back of the pass side fuel rail that you can hook up a fuel pressure gauge. That will tell you if you are getting the right FP and you could at least rule that out as an option.
