Have a 95 civic ex with d16z6 one day driving an I was getting on it....next thing I know the engine just goes to redline anytime u even touch the gas, but at idle it will surge from 1k to 3500. And again any tap of the gas an it goes to redline. I tried getting cel but it just stays solid light no blinks. I thought it might be the comp so I tried a different one still no difference. I tested the Tps an at wot it it reads 4.9v which is to much is this the only thing tha Can cause it????
 
The surging is likely the FITV (fast idle thermo valve). It's a super easy fix. The repair is well documented here.

4.9v is close enough for WOT on the tps. What is it reading when the throttle is closed?
 
The reading when it is closed is at. .49v....but the temp of the engine is what th3 fitv goes by right,because the car warmed all the way up but still had the ridiculous surge
 
well hold your finger over the fitv hole in the tb and see it it fixes it
