So, like I said in the other posts - oil change and spark plugs to come. Done and done. I went with dino-oil with plans to do the autoRX thing and switch to syn but it looks like I am losing some oil below so that will have to wait until I investigate. I certainly don't want to make things any worse.

I used AutoLite Platinum plugs.. opinions welcome.

The reason I replaced the plugs is because things felt a big sluggish. I know how everyone talks about how slow the 3.0 is but mine is less perky than it should be I think. Things are definitely a bit smoother with the new plugs/fresh oil, but I am suspecting that maybe there is a vacuum leak causing some hesitation upon acceleration. I hadn't messed around under the hood much until last night. I don't think I have ever seen such a mess of vacuum hoses.

The QUESTION I guess is where to start looking for the air leak and other potential power losses. Thanks for reading!

Oh. And my next project will be to replace the blower motor resistor. It only works on fan speeds 3 and 4 (of 4).

Easiest way is to get a can of sensor safe carb/intake cleaner and spray the vacum hoses and fittings one at a time and listen to the motor. If you spray a hose/fitting and the motor RPM's increase without touching anything else then you have found a leak. Works every time.

I have to replace my blower motor resistor also. I have speeds 1,2 & 4 but no 3.
