I have a 2000 Ford Taurus 3.0 OHV that is making a strange engine noise
when I accelerate. The sound only happens when I aggressively
accelerate, at normal acceleration it doesn't seem to make noise. The
only times I notice it is when I get on to an highway or when I pass
someone on the highway. I first thought it might be a spark knock,
however the noise seems consistent not matter which type/brand of fuel
I use. Someone else thought it might be bad values. Its likes a knock,
tick, rattle type of sound (hard to explain). Spark plugs are fairly
new (10k on them), I put them in as soon as I purchased the car (used)
and its made the noise since I bought it.
Any ideas of what this noise could be? I don't want to have to take it
into a dealer.
I have tried 'r e v v i n g' the engine while parked and it doesn't
seemed to reproduce the noise. It only seems to make the noise when

As said before, start by cleaning the MAF sensor in the
intake tube. That vintage also had a problem with the DPFE
sensor which controls the EGR that will cause severe knock.
There was a recall on them. You should have the PCM read
for any fault codes. You can post them back here for a bit
more help. You need the exact code. Many auto parts stores
will read the fault codes for free on the hopes you will buy
their parts to repair.

Have the dealer run an OASIS check on it to see if it has
been replaced. That won't mean there is nothing wrong with
it; it just means it has already bee replaced under the
recall campaign. Also, I hope you used a decent spark plug
when you replaced them. You should be using the Motorcraft
or Autolite plugs. Not all manufacturers rate their heat
ranges the same way or, at least, it doesn't work out that
way in the engine. I still suspect your problem is in the
EGR system which is controlled by the DPFE sensor.
