I checked all vaccum hoses for leaks, cleaned my maf sensor, cleaned my iac, and even the throttle body while I had it apart. Spark plugs are all new, so that's not the issue. Still experiencing the problem. Today I discovered the 2 front motor mounts are broken as well. I'm not sure if this would cause an idle issue? I would assume so, being that with the motor mounts broken, everything would be knocked a bit out of whack.

Well first off two cracked motor mounts would almost definatly explain any kind of violent vibration from the front end. You need to REPLACE the mass air flow sensor 90% that thats the problem, cleaning the MAF will not fix a broken mass air flow and the car will definatly run like crap with a faulty mas airflow. If you have a CEL for it like I said thats more than likley you're main issue and should replace that first instead of chasing exhaust or vacum leaks that are probably not the real problem.

If the TPS sensor is bad the idle will hang drastically usually and surge at idle, to check for a faulty TPS simply dissconnect the connection to it and see if the idle changes and remains normal, if so the TPS is bad.
