3500 rev limiter?

[kwh924]

So I've been driving my 91 around for a little while and I notice that after you've been driving for a little while it won't rev past 3500 it just acts like it's hitting a rev limiter. Any ideas?

ummm idk i have never really heard of a rev limiter after driving a car for along time. you might have something wrong.

[bcjammerx]

auto or manual?

To me this sounds like some sort of sensor error, once the car warms up the car goes into closed loop...get wrong info from a sensor and either limits the rpm's via protection method and thus throws a code...or it's getting wrong info from a sensor and can't rev past that point.

Check codes.

first of all im pretty sure he knows he has sum sort of problem.. that was a useless responce imo.. try asking questions and trying to help him out with information that you might have about the problem, other wise dont post that crap.. second... do you have a check engine light on? if so try to pull the code from it as that could be a problem of many things... a lil more info would also be helpfull

[kentucky accord]

the car is going into "limp" mode because you have a problem somewhere. im sure you have a check engine light coming on too? it could be anything from something very minor (a silly sensor) to major. typically though, if its in limp mode, its something involving sensors/electrical.

check maf airflow sensor

check maf airflow sensor

uh you mean map sensor lol.

O.P
Does the car run any different? or is it just not revving past 3,500?

[kentucky accord]

check maf airflow sensor

yeah check that and the carburetor.

[reccakun08]

yeah check that and the carburetor.

wth? 91 is carburated? FI

[deevergote]

His point was that our cars don't have carburetors... or MAF sensors. We have MAP sensors. (carb'd CBs did exist elewhere in the world, though)

[Potatoswatter]

Wow, this thread is gonna be pretty confusing for the guy!

MAP sensor = intake manifold air pressure sensor. Google tells me it's on the passenger side firewall, which would put it beside the fuel filter, which is under the vacuum control box, which is under the vacuum diagram on the underside of the hood.

The engine won't rev because it can't tell if it's getting air.

[hondadiablo]

Mine was doing the same thing. I changed the fuel filter and it cleared up.

[kwh924]

Thanks for all the responses. As far a code It is throwing one but my I've never really pulled an obd1 code before but I will try to do that tonite when I get off work with a guide. And as to the fuel filter I replaced that in the past month only putting 600 miles on it sense. It doesn't feel like it misses or anything but it does feel like it could run better.
