Okay so the otherday i was on my way home and my check engine light came on so i was like WTF !? now my car wont pass 4k RPM and the check engine light goes away after a while and the tends to turn back on. I have to turn my car off at a stop 2 pass 4k. Any idea what this bugg is ? (K20A3) EP3

bring it to autozone or kragens/checkers to see what code you're throwing. when you go into limp mode, you can't rev over 4k.

Yeah some guy told me his FG had gone into Limp Mode but it went away .

Ima throw in my scanner right now and post the codes it had right now brb.

Ok so it gave me this code :

P1259

Manufacturer Contrl
Fuel Air Metering .

check your gas cap, if its not sealing, you fuel pump can not get the right fuel pressure=limp mode. While you are at it, check your oil level, that gets to low and the motor will go into limp mode. After you find the problem, with the key off, pull the ecu fuse from the box under the hood, this will reset your ecu.

Damn, you got a EP right? I'm glad you got your car figured out, but tell me this, when does your vtec kick in hard? Or was that a joke seeing how you have an A3 and all...

mustclime

Yea, the a3 vtec is a monster.........

josh's ep3

Oh I know dude...

Why do you guys make fun of your cars?

mustclime

The I-VTEC in the k20a3 is not much to brag about. You only have the extra cam lobes on the intake side and it "kicks in " at 2200 rpm....you see, the k20a3 runs on one intake valve per cyclinder till 2200 rpm and then the vtec starts using the other intake valve.....so if you drive a k20a3, vtec is kinda a bad joke.

Blackcatn2o

ooooookkkkk what ever floats your boat!

ek_sleepr

Yeah dude i know i was exagerating ..... you swear my a3 vtec kicks in like that lol

I would think that resetting the ECU probably got rid of the limp mode, and would have even before you did all of the maintenance items.

P1259 is "VTEC System Malfunction." (According to a google search) I don't think the gas cap helped you at all.

Either way, all of the maintenance you did probably made it run better.

mustclime

that code comes up a lot when you are a qt low on oil....20wt oil sucks.

stickyicky

p1259 is a vtec malfunction...meaning your low on oil or something else more serious is wrong with the vtec system.
Changing your oil would do the trick, but you have to think why you were low on oil???
