Speedo surges on acileration
I have an 02 xlt with A4wd 130k. I've only had it for a month, haven't driven it a whole lot. It starts fine, idles fine, drives fine..the issue I'm having is when I accelerate, i.e. passing someone on the highway,the speedo bounces up and down about 2-3 mph, and the truck surges and stumbles a tinny bit. The rpm's don't fluctuate, only speedo. If I mash on the pedal and downshift, everything is smooth. It runs smooth at any constant speed. Only happens when acilerating.
Recent things that were done to the truck are, I had the transfer care rebuilt a few weeks ago, and I used some 'engine bright' to clean the engine bay a week ago, and I think it started to have the issues after the engine bright...
Any input would be great!
