I have a 87 camaro with a 89 GTA 305 tpi in it my check engine light stays on unless I unhook the harness to the esc, or I unhook the plug used to set timing by firewall on passenger side. Only code I get when I check codes is 12. Timing is set at 6 degrees have replaced knock sensor. Any ideas?
And the ignition module is new. I just took it out and the ses light went out after keeping the rpm's up for a while. After I go back to idle or give it pure hell the light goes back on.
im checking codes with the check engine light, the scanner at orielys would not comunicate but with the way the car was turned from tbi to 89 gta tpi i don't know that all of the wires were sent to the aldl plug. If I knew for sure how to tap into the plug of the ecm and jumper it to a scanner I'm sure it would answer my question. But I really dont want to fry a ecm.
"When you find the adapter, jump A and B with a paper clip.
Next turn your key on but don't start.
Watch your check engine flash the code/s.
EXAMPLE: CODE 12: one long flash and two short flashes CODE 13: one long flash and 3 short flashes
Note: code 12 is usually the first code you get and just ignore it. Watch the code after code 12, that's what you need. Let me know when you got the code so I can guide you to the fix."
These dont show any other switches in series with the ses light that would cause it to come on. Is there anything else that will cause this light to come on other than the ecm?
