Is it actually running poorly or are you just getting the CEL flashing? Honda has a service news article about aftermarket drivebelts causing a cel with no driveability problems. In these cases the ecu is detecting a misfire where there is not one present. Check and see what codes are stored in the ecu.
my '01 CL-s had a flashing CEL about 2 weeks. i was getting on it a little hard to see what the car had in it, turned off VSS, and floored, wheel hop, tires spinning, then a saw the CEL. i turned off the car, restarted it and never saw it agian
Those year CRVs have common problems with fuel injector failures. I'd check it out as soon as possible. As was stated earlier, the MIL only flashes when a catalyst damaging event (such as a misfire) has been detected.
This is a public forum with over 1000 people on-line right now. It is as much their right to tell you they don't like what you say as it is for you to post it in the first place. Grow up and learn to accept criticism without flying off the handle.
does the flashing check engine light occur before the vehicle is started? like with the key in the 2nd on position? if so, then that's just displaying readiness codes. not really a big deal. but if it's doing it while driving, then it's a potential catalyst damaging situation, and should be fixed asap.
most likely if it's a b20b or b20z crv, and you have p0301, 02, 03 or 04.. your exhaust valves have recessed into your cylinder head on one or more cylinders. you'll need to replace the head. honda usually goodwill's the head, and all you have to pay for is labor.
ps- if this IS the case and you need to swap the head, then i have a good one for sale.. cheap. 2001 b20Z head with 35,000 miles on it. let me know.

I just bought a 2001 Honda CRV for $13,000 two days ago, it has 65,000 miles on it. Yesterday I noticed my check engine light was flashing and the engine was kind of shaky -it had no pick up, it appears to idle low and seems to putt-putt- almost like it wants to stall. I'm bringing it back to the dealer that I bought it from on Monday but I don't feel like I can completely trust them. Does anyone have any ideas on what could be wrong with it?
Sorry to resurrect an old thread, but this exact same thing is happening to my friends CRV. I changed the timing belt and a month or so later, OP's problem occurred. I really don't want to take off the head again unless I'm ABSOLUTELY sure the valves need replacing.
How can I be sure before I take the head off? I have spark to all plugs and the timing is dead on. #4 cylinder is misfiring, the rest are good. Injector resistance is good, injectors were soaked in cleaner prior to re-installation.
