I leave near Springfield Ma. I'm going to see what happens since I've cleaned the wires and plugs to the coil pac and the maf screen so I'm hoping that's all it is, I can only reach three of my spark plugs,I'm not going to take a chance right now to deal with the spark plugs if they are to rusty don't want anything to fall into the motor. I do have a regular mechanic his awesome but can't afford to do a total tune-up. I will check the iac valve and the sensor to the maf. I'm so thank full for people to help me out.
