93 Q45, runs rough after battery change??

[jsch3]

hi....just changed battery....I thought that computer resets automatically when new battery is connected. Obviously it could be a coincidence and something unrelated happened at same time as battery change....but wonder if there is anything I should do before starting what could be a diagnostic goose chase. I tried connecting/disconnecting battery....still rough.

Check the quality of the ground connection, then check the integrity of your MAF connection.

Have you replaced your timing chain guides? If not, go to www.nicoclub.com and read the timing chain guide article.
