Ok, so i have a 93 civic hatch with a b18c1 swap. The b18 has about 80K miles on it. The thing is, my throttle response seems to be crap. However, this is only after the car has warmed up. If i tap my throttle, the RPM goes down about 100rpm before it slowly rises to about 1100 and then resumes idle at about 700-750. Another thing, it refuses to hold a certain RPM, it fluctuates about 100rpm up and down most dramatically when I try to hold it around 3000RPM. The engine has the original O2 sensor as well as ECU. Ive replaced the spark plugs recently and of course kept the oil changed. I don't drive my engine very hard, but I try to get it up into the 7000s sometimes because it seems to run better after that, almost like its clearing some gunk or something out. It has a vafc on it but i havnt changed the fuel map because i havnt had the time or money to get it tuned or get a wide band O2 sensor for it. I have checked the map sensor and it is within the resistance range specified. I had a thought that it might be the O2 sensor but i thought I might see what you guys had to say about it first.
Thanks in advance,
Daniel
