Motor seems to missfire a little at idle on a 2000 Pontiac Grand

I had my 2000 Pontiac Grand Am 2.4 diagnosed for troubleshooting codes but no codes came up.The mechanic told me it was my front left transmission mount. Would a bad trans mount cause the motor to seem to misfire a little.Because whenever I rev the engine a little to 1000RPM it seems to be fine.The motor does tile to the front a little.

Sounds like you have a bad mount if it is vibrating at idle, and goes away with RPMs. Most of them I see are the front motor mount, not the front of the car, but the front/timing side of the engine. Easy way to tell is to take a pry bar and pry up while engine is running. If it goes away, you have found the mount.

Problems with 2000 pontiac grand am

If it is a 2000 model and running rough, the check engine light should be on. If it is, you need to get the computer scanned to point you in the right direction to troubleshoot the problem or problems.
A mechanic would look at that and find out which cylinder is missing.

P0480 has to do with cooling fan relay, fuse, circuit or the fan it self, start car, turn on A/C the cooling fan should come on with a/c on and car in park engine at idle RPM. If it don't then you will have to troubleshoot and find out what has failed.

Blower motor stop working on 2000 Pontiac GP

Two possibilities I can think of. #1. The blower motor itself is dead, or #2. The blower motor resistor is fried. Blower motor resistor, however, is more known for taking out certain fan speeds, such as the lower fan speeds.
