The car runs bad at idle no matter if it is cold or hot. I just run the car and sprayed the crap out of the intake manifold and vacuum lines and nothing. No change.

That is actually a really good idea to test the injectors. I guess cause the car won't start because of no gas ending up in the cylinders you would just need someone to crank the car over and over right?

I do have a code reader. The only code that has been coming up periodically is 2188. Running rich at idle but don't have the smell the strong exhaust. I have thought of getting a real time scanner. Would that tell me if the timing (however prossible) would be off and if I sensors was off but not throwing a code?

Lastly while at idle in park I noticed a rattle from the drivers side. You can hear it well in the car but know it is coming from the engine area. The rattle seems to happen when I push the brake. Brake booster or line maybe? I know that it has a oneway valve. Could that be causing a leak in vacuum or something? Guess I could remove the line and plug the outlet on the intake to see.
