Yeah it was the plenum/intake thing that I didn't want to mess with but seems I must. Oddly enough the chiltons guide doesn't even mention it and basically says how to do passenger and to only do 1 side at a time to avoid confusion....big help there since they are quite different. Is it possible to reuse the gaskets from the intake since they are metal if I remember right or is it once they are removed it's best to replace them thing? Just asking since they are easy to get at and my funds are running low for the moment.

I also checked my pcv valve today and it was shot..could barely blow any air through it at all so that at least was an easy $3 fix.

The truck has gotten 15mpg since getting it and I am of course trying to get the 20+mpg that many owners seem to get so I'm wondering if I should look at replacing or cleaning anything else?

Stuff done in last week were replaced all the belts, hi- flow water pump, PCV valve, air filter, new Denso dual plugs, cleaned the throttle body, replaced 1 valve cover and planning to do drivers side here shortly and will look for any height changes in the half moon area since I didn't when doing the passenger.

Once again thank you for comments so far and even though I haven't tested the mpg since all the changes I'm open to any advice on anything that could help improve it. I'm still pretty new to all this and have been lurking the forums and the repair manual before doing anything myself since I would have been completely <img src="/forums/images/graemlins/confused.gif" alt="" /> without them.
