car doesn't rev past 5k (ka24de)

[joshchewuhh]

Well my car doesn't want to rev past 5k in 2nd-5th gears. The RPM bounce like it was hitting the rev limiter. Now my car does have the CEL light on and it throws code 32 (egr malfunction) do you think that will cause my car to have a rev limiter at 5k?

anyways i've searched this and came up with cutting the 5th gear sensor on the tranny. Well I did the 5 spd swap about a year ago and i didn't plug the sensor in so I know its not that.

Try checking your wiring!

Did you wire any sensors during your 5 speed swap?

[joshchewuhh]

what do you mean?! >_<

what sensors to be exact

[essforteen]

4th gear and 5th gear sensor! Thats the only problem or it could be your coil or distributer!

Does it feel like a fuel cut or ignition cut? Harsh or not?

[johnksoy]

im having a similar problem. It feels like I hit the rev limiter when I hit around 4k rpm in 4th and 5th gear only.

also have bad cold starts.
speedometer doesnt work either. Just throwing this in just in case the problems are related.

Any insight?

Oo my lil bro is having the same problem, but his bounces at 6..wont pass that. His is original 5speed..seems like essforteen might have a clue whats happening..

[griprus]

its your o2 sensor

what happened to me it wouldnt rev past 5500rpm what i did i had a wrong sensor on my tranny it was the 5th gear i believe or 4th just unplug them both are u should fix it... keep reverse lights though

[LegitSeller]

assuming its a ka. check your grounds to the far back right of your head exhaust side. it might have melted or not be tight anymore.

Reson being, ive seen a motor swap which started up fine, ran, but it revved to 5k then bogged out. even while driving itd bogg at the same rpm. The check engine light also came up at some random times. looked under the hood the two grounds near the exhaust were loose one was almost melted. Fixed it and the car runs perfectly.

Hope this helps might not. whatever. goodluck lol

clean your maf check old vacc lines good luck

i had same problem, and it ended up being my MAF sensor.. it was done.. i replace it and RPMs were all smooth.. I only changed the maf sensor and cleaned the plug.. thats all i did.

[towlie]

Same thing happened to my boy, would hit rev limit at 2k.. Ended up being a dirty MAF. Replace it and see what happens (don't use maf cleaner)

[cookie_monster]

^^^^ you guys should try cleaning your maf sensor. Cause one of my buddy have the same problem and i bought over my other maf sensor and we just swap the maf and his car ran fine. so yea give it a shot.

X2 maf sensor

ive seen this on a few KAs

Check or clean MAF

I was surprised but the 4th gear position sensor has caused this before for me too...

cheers and good luck.

bump


in 1st - 3rd gear i can redline all day

the second i shift into 4th or 5th now all my gears and car is limited to rev at 3k untill i turn the car off and turn back on and dont shift into 4th or 5th again.


should i just unplug those two sensors?

[blueshark123]

give it a try it doesnt cost a thing

[OiyItsC4ry]

Yeah, replace the maf. Imo trying to clean it only costs you more money. Safer way is to just buy a new maf.

i had the same problem but instead of not reving past 5k on 4th or 5th gear, my car could not rev past 2k on neutral and died once i put it in first gear.

what i did and solved the problem
- changed o2 sensor
-fixed the maf wiring because the wiring was bad and shitty
-lastly tune up (plugs,wires, cap and rotor)

then restarted the computer and BAM!! my car was running again, reving past 2k rpms and driving strong.

hope you find and solve the problem to your car soon
