When I am just cruising between 70-80mph keeping it steady, I start getting a VERY VERY slight miss. It may not even be a miss, but that is what it is feeling like.

Over 80mph or if I'm accelerating, the car runs great, or atleast I don't notice it.

I have replaced the Cap, Rotor, Ignition Coil. It is an ls/vtec. I just replaced the rings. Did a HPDE last weekend and car ran F*CKING great. Not one issue.

But just driving to work and back is when I notice it. Only between 70-80mph.

I'm stuck. I'm thinking maybe the distributor is going bad and/or the fuel pump? Maybe fuel filter is clogged. Running NGK Iridium plugs. I just don't know. It just confuses me how it runs great during acceleration and high speeds, just not between 70-80mph.

Fuel filter. My da did the samething.

code(s)?

curious as well, mine is kinda doing this too. I replaced cap, rotor, fuel filter, next gonna try plugs. Also i have noticed on my Air/Fuel ratio gauge the status LED's that show kinda what ballpark ratio your running, is not longer concentrated in one area, instead its spanned across the whole range and didn't start this until my problem started. So it could be my o2 sensor sense it is about 5 years old, i'm not throwing a code but maybe it could be your problem as well..

Alright, well I replaced the fuel filter. That did not solve anything. I bought a new distributor and will install it tonight.

I would say, O2 slow response. Is it doing the same in 4th gear driving 40-50 mph?

Not sure, I'll have to check. Also, no check engine lights. It is an 00 GSR with OBD1 jumper harness and hondata s200.

the light may not necessarily be on, but a code(s) can still be stored.
always check for codes. insure that what you are changing is the cause by isolating the problem. never just fire parts blindly

No codes

I'm thinking now its either an exhaust leak sucking air back in or electrical. This is so fcking annoying especially since the engine runs great and overall the car does too just for this stupid nagging issue.
