Thanks for the information. i forgot to mention that i replaced the valve cover, not just the gasket.
So last night i did the following
-used compressed air to clean out the spark plug well
-replaced all spark plugs- these looked really bad
-replaced all coil packs
-inspected all vacuum lines, found the break booster hose cracked and used tape to seal temporally while i order a new one
-cleared all codes

The car cranked up and, slightly rough at first then smoothed out. I drove the car to the gas station, filled up with 87 and added a 1/2 can of sea foam. Upon my return to the house the check engine light came back on. The distance from gas station to the house is 5 miles. This time i checked the code and got P0171 system too lean on bank one. Note this is the first time i have had this code.

My thought is that the sea foam may have somehow helped to trigger this. I plan to drive it daily over the next week to run the gas out of the tank and then see how it works.

Any other suggestions.

Thanks, so i am still waiting on the new brake vacuum hose and will install once it comes in. I checked a few other items.
SHRTFT1- was at .8% at idle , not much of a change at increased RPM
LONGFT1- 20.3% at idle, 20.3% at 2254 RPM- no change at 1600 or 2500 rpm
MAP- 8.9 at 680 RPM, 8.0 at 2254 RPM

Will check all readings again once new hose is installed, will be a few days.

Thanks everyone for the help on this. I replaced the vacuum line and reset the computer. Drover the car for 40 miles yesterday and no check engine light. I think this has fixed the problem.
