Hey guys. Okay, so i am officially frustrated with this. About two weeks ago, my car started throwing CEL. I found out it was code 9 which is Cylinder Sensor (CYP). So I looked up previous threads before posting a new one and found a few things out. First, I was using an MSD Dizzy with External Coil, and someone said they tend to make your car throw CEL, but I'd had it on there for about 5 months with no problems, so someone said to do a new Cap and Rotor. Done, still CEL. Then, I read you need to change out the entire Dizzy, so I got a BRAND NEW OEM one, once installed, CEL didn't even hesitate to pop itself right back on. I'm at a loss now and don't know what I should do. Its an OBD1 completely converted from OBD0 from RyWire. I also saw that I should check my wiring. Came to find out that one of the Dizzy pins was loose, fixed that and CEL was gone for about 24 hours, then came right back, checked again and they were fine, now what? Keep in mind, I got it tuned and they had to bump the timing, its completely advance...could that be it? Should I try doing the timing and setting it to TDC? Thanks in advance for any help you guys may be able to provide, anything will help at this point...

 

did you pull the hazard/ecu fuse to reset the ecu when you did this?

IDK possibly, try setting it to 16 degrees.

 

pull the bulb in the cluster, problem fixed!

Try what grog said then report back.

 

I pulled the fuse and disconnected the battery every time I tried something new. I just tried pulling the fuse without disconecting the battery and it still comes on. I was thinking of pulling the bulb, but I forgot now I have the CEL Shift Light on there from the tune...

 

PM me your e-mail address and I will send you the troubleshooting flowchart for a code 9.

 

i had this code before check all your wires on the rywire harness one came loose on mine
