Any notice differences with new TPS?

97 4.0 4x4

Put in a new TPS and my RPMS seem higher than before and it feels like my shift points got a little higher t0o. Feels like she is sucking in more air.
(can't complain about more sucking)

Have any of you had anything similar.

Hahaha dirty.

Anyways, did you take off the throttle body to do it? If so, I'd suspect a vacuum leak. With the car running, spray some TB cleaner around the TB and see if any of it gets sucked in, if so, you've found your leak.

Also, just because it's a new part, doesn't mean it's a working part. For example, I bought a new oil pressure sending unit, and it made my gauge work even worse than before. Hopefully cruiser54 can chime in on how to test a TPS

I agree with 1996 here.....vacuum leak is a possibility. So is a flaky sensor. Where did you buy it? Aftermarket automotive sensors
are kind of "hit and miss".
