Hi, I have a 97 CX with 185K miles. When the engine is under load and at low rpm, like starting up a hill with AC on and maybe having to upshift, the engine "misses" for a split second. It seems like the fuel or spark is cut for an instant. If I downshift and rev up, the engine runs normally. Definitely happens when I lug the engine, which I try not to do in general. This seems to happen once per acceleration in the lower rev range but I can avoid it if I rev up the engine prior to starting out. I know this a vague description but I thought I would throw it out there... I replaced the fuel filter a few months ago and it had literally had a few spoonfuls of a tan, cookie-like substance, very crumbly. I had previously changed that fuel filter about 30K miles ago, so it wasn't that old. Also, as a rule I do try to hit the newer gas stations but...?? I also cleaned the probably original PCV valve a few months ago but I will go ahead and replace it. I will give the car a full tune-up with distro cap, plugs, wires, PCV, etc, and see what happens... Also, I am curious if anyone has an estimated life span of a ignition coil for a 97 Honda? . I replaced the O2 sensor at 150K, not because of any noticable CEL problem but the gas mileage seemed low, I am wondering if replacing the coil would make a good "matter of course" replacement along the same lines. Any thoughts on the above stuff is appreciated, if you are still reading at this point!! Tim
