I have a 93 cx with a swapped d16z6 block y8 head i wired the 4 wire o2 and vtec has been running great for about a year until lately it has been sputtering and when it idles it surges and dies. almost like it isn't getting fuel. ive replaced plugs and wires not to long ago and dizzy is pretty new? also when im on the highway i can smell gas? thinking about a walbro 255 will fix the prob.

 

Ok......help us,help you. By any chance do you have any codes? As in cel's? We need a more info.
