97 ex civic rev limit 5000
I have a 97 civic ex I just aquired and have been trying to figure out why it won't rev past 5000 rpm. Anyone have insight on this. The motor is stamped d16a. The car has a cold air intake and headers on it. It is manual and I have no clue what to do.

OP, check your head stamp for the head code, as well as the date stamp. They should be near (or between) your exhaust runners, and the year should be x|x, x both being numbers. Also, find your ECU behind the passenger's side kick panel and give us the numbers on it.

Re: 97 ex civic rev limit 5000
The oil is good. I replaced the cap and button. Tried the ckf trick didn't work just threw codes. I unhooked the vtec and didn't get a light. If I have to swap to obd1 what do I need to get? I'm starting to wonder if I'm waisting my time here

So far it seems you have a
P2J-2 - 1996 Automatic D16Y8 head
D16A - 1997-1999 JDM Honda Domani (MB4)
P2P-A33 - 96-97 EX coupe manual
Now I think you need to consider looking at the CKF (if it's there) and what intake manifold you're running (check if you're running a 2-wire external or 3-wire TB internal IACV). Because you're running an auto intake manifold (assuming it's the same IM with the head) with a manual ECU. This raises a red flag, unless my research of the P2J-2 code is wrong. CHECK YOUR INTAKE MANIFOLD FOR IACV SETUP AND FOR CKF .
According to this guy, the D16A doesn't have CKF, but I'm not entirely sure which D16A he had.

This is the CFK Bypass trick in case you need it: http://ff-squad.com/wp/?p=309]
Also, is your ECU modified? Chipped? Probably a poorly tuned launch control/2 step.?
CHECK YOUR ECU IF ITS CHIPPED.
Is your mechanical timing correct? Jumped a few teeth? Check your TDC that the cam and crank line up as well as the pistons.
Consider using another P2P ECU (depending on your IACV setup and whether you're running OBD2A or OBD2B)

Re: 97 ex civic rev limit 5000
Already tried the ckf bypass at got a cel. If I keep trying to run over 5k I get a cel multiple cylinder missfire. So what head is suppose to be on a 97 ex manual?
