I have two questions about my X...

1. My car when it is stopped at a stoplight, or parked it tends to idle a tad bit on the rough side. IAC valve was just replaced. lower intake manifold was replaced too. Do you think I should clean the MAF? Maybe the wires and plugs? I am up for suggestions!!!

2. The very last plug on the left hand side is there a trick to changing that plug? anyone got any ideas to make it easier. there is that big electrical box in the way.
ANY HELP would be appreciated. thanks

Try the MAF first.......

On my 97 when I do the plugs:
The right wheel comes off, the skirt in the wheel well and I get every extension and universial I have handy and take my time. haha 1/4 and 3/8
 






have you gotten the manifold gaskets replaced yet. i would clean the maf first but if you are on your original plugs it is time for a change
 






SOMETIMES!
Disconnecting the battery to reset the puter and then take it for a "relearning" drive may help
 






ok i have some what of the same problem i stop at a light, and then it will jerk forward and idle alittle high, then go back to normal when i drive or it will run like i just got alot of juice under the hood, i dont know whats up with that, any help
