while cruisnig, my check engine light came on out of the blue. previously, everything was fine. the code was for the knock sensor, and i noticed the car didnt feel so strong. then the idle changed, it would climb to 1700 and fall to 700 over and over. and i jumped the ecu again. now i had codes for the knock sensor and the egr lift sensor.

i replaced the egr valve and warmed up the car. it still couldnt hold idle, but it drove normally and the cel wasnt coming on. it would usually come on after about 5 min of driving, and i was out fot about an hour. the cel eventually came back on and the car wasnt driving normally anymore. i checked it and it was for the EGR again.. i am confused.

has anyone had any similar problems? does anyone know the solution? any and all input is appreciated. i need opinions before i go out and spend money. and i did search before creating this topic.

 

So no knock sensor code anymore?

 

no more knock sensor code, just the egr

 

the knock sensor code might come back when you get on it again....free bump

 

since the light came back on i took it to 6k twice, and i only have the egr code

 

i was out just now with car running and i was looking under the hood for anything out of place. i found a stray vacum line to thr intake manifold and it put my idle back to a steady 500rpms.. i just have to drive it and see if it is ok....hopefully this is the end of this topic. if it isnt ill ba back

 

could it be the vacuum line from the IM to the EGR

 

dude I recently did a jdm h22 swap in my 4th gen too and EGR was making my car run like straight ****. I ditched the p13 and got a chipped p28 from ih8ricerz and god damn does the car run great. I couldnt find anything wrong with my EGR unless the problem was with the EGR itself. Just my .02 cents.

 

everything seems fine now since i plugged in the stray vaccum. its driving normally againi think i solved the problem
