Have you cleared the PCM/ECU?

I am having similar problems, only it goes to 3500 rpm. supposedly it is the crank position sensor, on mine anyways, but I have replace my dist cap already, I am hoping it is just a bad part and can replace it. Otherwise I don't know, but good luck with yours hopefully now you have a starting point

chad olson

the year of my accord is 1990??and yes the cel is on all the time??no i did not clear the ecu???how do you clear the ecu??????and why does it only rev at 3,000rpm??????

From your other post and this post, sounds like you have an ECU problem.

my Honda start but won't rev pass 3000rpm,,what could be the cause

someone already posted it, strong chance its the ECU

i had the same issue. my crank sensor located on the drivers side of the block had some chafed wires, causing a short, and not letting it rev past 3000. Go to a yard and get this sensor. I got mine for $100, the dealer will charge $469, thats not installed either.

Check for codes.
If your car has VTEC, check your oil level.

I have 97 Accord se since I got the car won't go over 4500 rpms
in 2015 I replace a engine I put f23a from 99 accord but just the engine
I'm using my f22b2 non vtec
distributor
automatic transmission
intake
wiring harness
I have cel my catalytic converter its bad
i replace with another one but don't have the plug for the o2 sensor
i put in N and i push gas and rpms go to 7000 rpms but smells like burn gas...
when i run the car fill go slow and I can hear a noice around the crankshaft pully when I push gas.

Now what if we have the same issue but no check engine light. I have a 1991 ex 2.2 and it runs rough and after trying to get up a steep hill in 1st gear the car would not even reach 3k rpms eventually dying at the top. I had to let it sit for a while before it start again. I reset the ecu and the car started but the problem continued. It died every time I tried to go up a hill without reaching speeds before. eventually the car died and I was unable to restart it. I think due to the battery dying.
