Fuel and air filters both new
No lights or codes
Have checked and replaced all vacuum lines that even looked like they might be bad
AC delco plugs w/ correct gap
Have not checked base timing don't really know how and do not have a timing light
EGR new
PCV valve new ac delco
Going to check the base gasket

Truck did pass AZ emissions and does act worse when taking corners.
Is there a tool I could rent from autozone to check fuel pump pressure?
also the truck sat for 3 years and my Dad tried to start it with the old gas in the tank, drained the tank used pea gravel and diesel to clean tank and finally gave in and bought new tank put in on the 23rd and at that time replaced the sending unit, in tank screen and chassis filter. when I first got it running ran a can of seafoam thru it. I was reading on here and think it could be the TPS as that seems to control all of the things that are acting up. Also I talked to my Dad yesterday he is 72 and his memory aint to good anymore and he told me it was starting to run bad when he parked it in 2008.

thanks for any advise as I really love this truck as it was my dads and now is mine.
Yes most AZ STORES RENT LOAN OR SELL FUEL PRESSURE TESTERS.
Also they can ckeck for codes while you are there.
