alright so i have a jdm b18c i just rebuilt the motor and put new pistons rods and a crank in. it will run and idle just fine. i can slowly rev up my motor to about 2400 rpm with no backfire but when i get to that point of 2400 it seems to be redlining at that point i've checked my timing three times it seems to be perfect i've printed out a vacuum diagram it seems to be ok. i have been thinking it may be a sensor or a fuel problem but i dont see how that could be. if you have any suggestions let me know please.

 

1 this will be locked you cant not sell anyhting being a trail member

2 do you have any CEL? sounds like cel problem

 

yea i do but i havent checked it. i was thinking about buying a obd1 reader and checking the flash codes but havent had the cash yet but i've been told by a couple people that it may be a fuel problem. do you think it could be fuel pump or regulator

 

ur not going to buy an obd1 reader just jump the wires and read the code from the light

 

^yup no obd1 reader...

jump wires and count the long flashes then the short flashes.

thats why you cant go past 2k because the ECU put you in safe mode cause you have too many CELs

fix all the CELS and youa re golden

 

ya what he said

 

alright i'll check that out and see what the codes are thanks for the info

 

my brother did the same thing.l it was a broken ignitor or something broke inside the distrutor. we replaced it and it reved to 7. but it was a d15b2. but just thought id put some input in.

 

^he has CEL issues which means the ecu is limiting his revs to protect the motor.
