Sometime the speedo will bounce around but not always.

 

Not always.. Some report "kicking" like misfiring.. Some report feeling of engine cutting out and truck just coasting for a second. Some times speedo just dies.. Many different symptoms

 

Well I installed the New TPS. You were correct it was the easiest task.
Now however the engine is idling at 1500 and occasionally climbing up to 2000.
Any thoughts on that? I was careful to place the TPS at the orientation on install so that it wasn't rotating the throttle.

 

IACV (clean) - or engine coolant temp sensor (one with square top) unplugged?

 

So the local parts house TPS's are ok? I have never dealt with the TPS.

One other issue I have had is that mechanical linkage that is part of the throttle/cruise control system. Mine has had binding, I removed c/c and the portion where the bracket is has been loose a time or two. I know the manuals says that is not an idle adjustment, but if it is either loose or adjusted wrong, it does severely impact idle and it can ebnen bind and make Rapid Wide Open Throttle Syndrone occur. That was fun in traffic.

 

You need to get the engine to full operating temp, then loosen the screws that hold the TPS in place and using a live data scanner turn it until your RPM are in the 650-700 range with no load on the engine, i.e. a/c off, lights, stereo, heater...all off.
You do this with the engine running of course.

 

Can I perform this adjustment if I replace the live data scanner with my live wife reading the tach and yelling its position at me? Or is more accuracy a requirement?

 

So did TPS solve the stalling problem? My 97 does the exact same thing.....was about to replace VSS. Curious if TPS worked before I order VSS. Thanks

 

re: with my live wife reading the tach and yelling

Yes, but we want a video....

 

Of her not you!
