Re: 2002 Bonneville acting funny, but only when cold???

Check codes?

Might have an ECT sensor giving wrong data, since this clears up as it gets warm............

Check the usual....see if runs better cold with the MAF disconnected.....check the f/p regulator vac line for fuel.....

Check for a vac leak......

Anything done recently to vehicle?
