I got a 94 Sedan with 181+ miles on the dash. I went to Houston Texas one wekend and I put my car in the garage while I was gone, I got in it and drove off real slow as normal and it felt like it was studdering like I had bad gas, it sat up for 3 days on a half tank, i thought it was bad gas so I ran it out out and it still was hesitation but after about 25 or 30 it will smooth out. I changed the plugs, wires, rotor, distributor and it still is doing it. I called A Honda dealer and I explanied to the Tech what I was having a problem with and he said right of the bat my EGR Valve were clogged up but he wants me to put it on a machine anyway. If any body has had any problems with this, please get at me so I can get a headup on it. The Tech said that the model I have (EX VTEC) after about 150,000 the EGR starts to go bad. Halla Back

 

Try Seafoam in the crankcase and intake (do a search). Also, try the other troubleshooting methods listed in the FAQ.

 

Whens the last time you changed the gas filter?
