My 99 Accord, V6, Auto, 130k hesitates when taking off from a stop and surges between 2-3k. It happened all of a sudden today. I don't see any obvious vacuum leaks.

I was thinking TPS that will make it shift funky. I used a scan tool and saw that the TPS sometimes take a little time to move from 9 to 20.

I don't have any codes

The tranny fluid is full and was just changed with OEM Honda Fluid

I don't see any obvious vacuum leaks

It idles OK but a little high sometimes over a 1K

 

I know with my wife's 2008 Civic the transmission had to be flush with about 100k on it. Now I just bought a 2006 and it seams to have the same problem. Do you all think that it's all related since they are both 4 bangers?

Sounds like you have the symptoms of a bad TPS sensor, hopefully a replacement will fix your problems.

 

Can we assume the spark plugs are up to date?
