Rep Power: 0

Hey guys my em1 hasnt been running good and i though id hook it up to a scanner and see wut the sensors are doing. everything is fine with sensors but for ignition timing whenever on load or just as i shift and try to accelerate it bogs down and slowly pics up. The ignition timing actually drops down to like 0 and even -4 when it does it. it shoots back up to 30 as i gain power. now i know the computer could be retarding the timing becuause it sees something wrong somewhere . i was thinking replacing the coolant temp sensor becasue thats the only thing i havent replaced. ive seen other bogging threads but lead nowhere i hope with this timing info someone gets some ideas?
