91 Si DOHC ZC SWAP.....CODE 9...LIMP MODE...3100rev limit...SEARCHED
 

ok guys here my problem...i have a 91 civic si with a DOHC ZC engine...it ran fine till swaped the tranny ....weird huh

just swaped the blown L3 for another L3

symptoms-
- started the car and it idles @ 1200rpm
- wont rev past 3100rpm
- i got a code 9 (No. 1 Cyl Pos)
- running rich the spark plugs are fueled up

what i have done-
- checked wires comming from the dizzy plug to the Cyl pos senser (DOHC ZC have it on the exhaust cam)
-had spare sensor and swaped it out (still ran like the same, i did reset the ECU 10amp HAZARD fuse)
-i did check the cam timming and thats dead nuts.

did i forget a ground somewhere?
where else can i look where dose it get its ground side on the circuit...threw the ecu everything went well except this.....

code 9 doesnt put your car into limp mode. i know because i ran mine for over a year with that CEL. so 1st, check for other CELs that flash after that one.

i found out that mine was a bad wire in my harness just above the ECU. 16yr old wires tend to be a bit brittle, and apparently it jsut broke. fixed it, and fixed my problem
