my car still hesitates sometimes, but never in vtec .i have no codes. i put a 255lph fuel pump in 2 weeks ago. i thought that would fix it but nope. i have replaced the cap and rotor. of course i have new plugs and wires. i only run 93 octane gas. i think it has to be my dizzy. my timing is good and it idles real well. it runsgood most of the time,but its that every so often bs thats driving me nuts. anyone got any suggestions?????

 

How many o2 sensors are you using?

 

yea mine did the EXACT same thing and I had the 02s wired backwards.
