scan for codes and check fuel pressure first. then check for a vacuum leak. also check for hoses with holes in them soft etc.make sure the duct work ging to throttle body has no holes in it.

302 is a missfire code for cylinder 2. it could be a plug, wire, coil, injector ,vacuum leak or low compression. all these need to be checked to find the failure.

based on the symptoms,the code and what this vehicle is i would suspect an intake leak when cold.sometimes they only leak when cold then swell and seal up when warm.i would suggest that you take it and have a smoke test done by a shop.
