300zx surges off idle

A&Q about 350Z
Q:


I have a friend with a '90 model 300. It idles like a swiss watch but if I try to hold about 2000 RPM it will just surge up and down. What do y'all think this could be? TPS possibly? He can make it go down the road but barely. I will go look at it again this morning. Thanks, Paul

I specifically posted it here because this is the only forum I use. I have never had a problem asking a question or two in the many years I have posted. It is not really that big a deal or that serious a problem with the car. As a matter of fact I answered my own question in the question. Turns out it was the TPS. I do appreciate the answer from txz082 though. It was my next place to look. Thanks for the input. Paul
