So i bought a new beater for the winter. Its a civic dx with a first gen b16 OBDO

I bought it for $1000, fixed up the body and painted it, made an intake and beat on it all week. I read that the redline was 8000, but I had a DX so I didnt know what I was revving to. I got used to where I would hit the the rev limiter and shifted before that, seemingly felt like I was revving out the gear

Well today I installed a tach, and whatdya know, 4800 rpm redline. Cuts power

Im throwing no codes. Only thing I noticed that needs some attention is that when you start it up cold, sometimes itll bog down and die, and if you hit the gas itll just die. Or if its only been going for like 15 secodns and you try and rev it, itll stuttter for a second at that rpm and then itll rev like normal. But will only rev to 4800

One sensor appears to be broken or atleast the wires pulled out, the sensor closest to the front of the car on the cylinder head under the distributor, I think a coolant temp, the wires seem to be pulled out if.

Oil level is fine

Need advise

Thanks

I also found that the check engine light was burned out/ swapped and Im throwing a stored code 6 and code 14

Cleaned IACV with carb cleaner, didnt do ****, reset the ecu and everything.

Dunno if it affects vtec or why I have this rev limit though

I guess I gotta buy a new coolant temp sensor

What would cause my car to not let me rev passed 4800?

So I changed the coolant temp sensor, nice factory harness clip and everything and that code is now gone

I also swapped in the very clean IACV but I still have the IACV code

I can now rev the car freely in nuetral past 4800 rpm

Also, when driving in first I can wind it out to about 6000, then you can feel its not making any more power. 2nd I also wound out to about 6krpm and again felt no more power

I did hit the rev limiter again once, seems to be about 6krpm

Its raining out hard so I cant really beat on the car, but I think the aftermarket tach might be screwy at those rpms or something, worked fine on my d16a6 a month ago though

I dont know if I have vtec or not, the first time I wound out first Im pretty sure I heard the distinct sound, but the second gear pull i didnt hear anything.

Also, for reference, I got 2nd gear up to 60mph @ the 6k rpm. Is that normal? LS trans maybe?

fuel... timing. wrong ecu?

crimsonv4mpire

map sensor?

cranny

hes have a code , most of the time if the map sensor goes , the car prolly wont run at all. timing vould be off slightly i guess , its possible. no spark knock or nothing? might be retarded too far. fire a timing light on it and check the marks on the pullys.

get that iac fix and go from there check the wiring on it.. on my year 98-98 dx's you have to move a pin on the ecu harnes in order for the iac to work, what year is yours? dx you might have to wire up vtec in order for it to pull

PINKS

Its a 90 Civic Dx

I have no idea about the timing

The redlimit as it stands now is 100% 6200rpm, I do not hear vtec engaging, tried multiple times

It is a PR3 ecu, which is correct for the obd0 b16a

Throwdown

i kinda had about the same problem it turned out to be in the dizzy.. maybe go there it work for me

PINKS

Changed the oil, reset ecu, cleaned the battery terminals and the car now rev freely and powerfully to 8k+

Im not gettin VTEC engaging though

The only code Im getting is for the IACV, would that cause it? I doubt it

Kinda stumped on why thats not engaging
