Thanks for the ideas

We've done these things, and also a very skilled mechanic also analyzed it. The knock sensor is something new to me until recently when I put my Bluetooth module on our 2004 TAHOE to analyze a "Check Engine". It reported a problem with the knock sensor, which after I cleared it hasn't returned...

Is there a reason my truck runs better on hi test? Is using regular with an additive a more economical alternative? Thanks!

So after struggling with the rough engine issue, I found that using hi test clears up the issue. Does that point to a defective component? TIA

Mine throws codes for that sensor occassionally, but there never seemed to be any connection with engine performance. I'll investigate it. Thanks.

Thank you

I checked and it's still pretty clean.

The symptom is not constant, but now when I am driving it seems at about 2K the engine starts to stall and I have to let up on the gas peddle and slowly press it. Can't use the vehicle until this is resolved. TIA

No Trouble codes.

Starting the engine in for the first time in the day, it revs, ten stalls. It starts and runs after that. Any clues? Thanks

I used the correct plugs plug wires and coil pack. I will need to look up the part#'s but it was a few months ago. I had changed the plugs, plug wires and coil pack cause it was way past due and also to alleviate the problem. speed bumps! That was how I was going to describe it to the forum...

2002 ST Sometimes when I press the gas at about 2K it feels like I ran over something small. I feel these little bumps. Otherwise runs idles smoothly, accelerates smoothly, not throwing codes. New plugs and coil. Thanks

The whole passenger side was rough. Thanks for the installation tip and the pn!

I wanted to avoid cutting off the connector and splicing up there in that confined space, but if that's the way to go, I will. it can't be too much worse than replacing #2 spark plug (!) Now it is the question of the right part number for the connector and whip Thanks for the suggestions.

Yes that's my situation as well. My question is where the pigtail goes where it can be spliced
