in a 99 civic si.. i was driving it and out of no where vtec started acting up.. it would just cut in and out between 5500 and redline. finaly the CEL came on and the codes are as followed:
P1259: VTEC System Malfunction
P1298: Electric Load Detector (ELD) Circuit High Voltage (ithink 1298 was the code)

has any one ever ran into this problem before?

 

did you check the oil level??

 

oil level was very low

 

that's the reason for the cutting in and out and the CEL for the vtec.. now we gotta figure out why the other CEL was on... anyone got an idea on this one??

 

reset the ecu change/fill the oil and go for a drive then check codes they are probly interrelated.

 

ya vtec prob was because of low oil. now sure about codes. first one probly was caused because of the low oil? id do what supra-n-civic said to do

 

thanks guys i appreciate it im gonna check that out tonight after work and give the results tomorrow morning

 

well the problem is solved filled up with oil and runs mint again thanks for the help guys

 

It aint mint again. Why was there no oil in the first place

 

true, do you have a leak somewhere or is it blowing it out the exhaust?

 

you could be burning oil!!! ^^
