'fraid not on the TV, I'd never get anything done out there. We'll have to figure out some time when one of them plays on Monday or maybe try a Saturday afternoon.

And just in case you're thinking the other TBF, it has a new timing belt and Porkensioner.

My guess is that it's a grounding issue or a Temp II failure.

Be sure to check the Temp II values at the LH/EZK as this will rule out any harness issues.
Will do, we'll meter it at the harness, so jiggling the wire doesn't fix it temporarily.

Ted, good call, we'll check all grounds including engine ground at the bottom and the ones at the back of the valley under the airbox and the battery straps.

Steve,

I just remembered you had an issue getting through inspection because you had no cats on your car, just headers. You were going to a custom shop in Keyport that was going to install the high flow cats.

Did you get that done?

If so, do you know if they welded or clamped them in? If they welded them and didn't unhook the LH and EZK they may have damaged something.

Did the car run like this before you had the cats put on?

Just trying to help isolate the problem and give more background to the tech heads on here.

No cats yet, I was hoping to buy a sticker and not have to change the exhaust.

It's feels like it's loading up. It has a very rough idle when stopped at a light in gear and you actually have to pop it in neutral to keep it running.

At high r's it's fine. when it gets sluggish and feels like its starving for something while runnig, if you can press the gas pedal enough times and finally get it to run, the high r's is what it likes.
