okay here is my problem....i have a 97 civic HX (d16y5) and after driving it for about a good 30mins i wont pass 4k rpms.....for instance, if u hit the gas to pick up speed and it hits 4k it just stops and wont go past it....if u put it in neutral and rev it goes to 4k put just bounces off of it........when i first turn on the car it runs good and everything its just after it warms up i guess that it does this........

oh ya someone told me it does this if ur running low on oil, but my oil is good....so i dunno?

 

do you have any CELs??

 

yep.....and they are for a # of things....like no cat/o2 sensors and what not stuff i havent had for a couple of years already......i searched and read around and found out it could be a # of things so0 ima just go to honda and let my friend run the comp on it see if anything new pops up.

 

Its called limp mode. Lowers rev limit, retards timing a WHOLE bunch. She must be smoking a lot, and sounding like a Subaru. Since its OBDII, then yea u need the scanner, no neat pin tricks to get a flashy CEL.
Anyways, Limp mode ( a.k.a. bullshit mode) i some sort of mode the ECU uses to protect itself, but to be functional so you can " limp " home. Fix your CEL's, and it shall go away after resetting the ECU. Good luck!

P.S. Some CEL's cause limp mode, some don't
I suggest u fix first the ones that do. . . which I'm not sure which they are specifically.

 

okay well i just got back and they usual stuff poped up......

but i also got some new stuff.....vtec and knock sensor.....there was on old sohc sitting out in the back so0 i got the vtec solenoid off of it....fixed that problem.....now i just need a knock sensor, hopefully that will fix.....


anyways tahnkz.!
