hmm sounds like a MAF to me 2..(just had to replace mine about 3 weeks ago and i couldnt be more happy)>> keep in mind that it was about 100 degrees today so im sure ur car didnt like breathing that too much.. but if the problem persists look into MAF

MAF yes, but could be the heat. In Toronto its about 38celcius+humidity pretty much been that way since the weekend and my car is sluggish in the heat. Prior to the heat wave it ran like a champ.

It seems to me that vapor lock occurs more on carb engines and very rarely in electronically injected engines.
My money is still on the MAF, esp if you can't rev over 2400 rpms and the car is bogging.

Max seems slow as well
I don't have enough post to create one but I have been having problems with the performance of my Max too... I have a 01 AE and it seems like my RPM's are increasing fastly but just not accelerating quickly. Earlier today I cleaned my Injen filter and went took a drive to see if I noticed a difference. Just when I thought it was acting better, I got dusted by a Mercury Grand Marquis, is that normal? I didn't floor my max but even if I would've I don't think I would have keep up. Any input would be appreciated.

Aren't those a Crown Victoria equivalent? If so, they have pretty beefy V8's, and on a straight away, they could go pretty fast i'd bet.

But I'm not sure if it's slower or if I've just gotten used to its power...

I have been doing some research and I noticed that the tire size can make a difference on performance. The car came with 215/50/17 tires, which is smaller than stock...could this make my car slower? I also noticed that my speedometer is not accurate
