Hi guys,
I have strange problem with my LT1. When I start the engine, check engine light is on after 3-4 seconds and both fans are on too. When I tried to read error codes with just turned key (ALDL paperclip method), without started engine, I have just code 12 which means nothing!?!?
Is there a chance to read error codes while the engine is working?

If it's a 94 and up the paperclip won't work. You need a cable and some software to look at to see whats going on.
