1987 Non-Turbo Spark Plug Question
 
I'm on my way to get a set of plugs and wires and cant remember what plugs not to get. Can someone steer me in the right direction? I know every plug doesnt work well in the car.

Go and Purchase 2 NGK BUR7EQ Plugs for the leading,and 2 NGK BUR9EQ's for the trailing plugs.
That is the stock plugs and they are the best for the N/A.
If you go Platinum plugs then just add a "P" to the Part numbers listed above.
Bur7eqp and bur9eqp.

I appreciate it . That actually solved half the problem. It has a cleaner burn now. Before I was smelling exhaust gases that I presumed were rich. Now I can still smell fumes a bit but not half as much. The plugs i took out were all 9's. There were no 7's in there at all.

Moving on to new issue: Lol.... Gotta love those FS's

The first issue is my oil pressure gauge is doing what it wants. I can start the car and it will go slam up to the top. Then it will eventually slowly come down. Then when I am on the highway and reving about 2gran it seems to show almost no pressure until I begin to slow down. I was thinking i have a bad sending switch or a short in the wire to the sending switch. Any ideas?

Second issue:

When on the freeway I have a vibration I thought was an out of balance tire or bent rim. They are fine. So when i went to get the oil changed i was told it could be a bent drive shaft or bad universal joints. Now I'm thinking about the torque os the engine and the weight of the car and I am trying to rule out a bent drive shaft. So I guess my question is for the experienced rotor head. Do drive shafts have a habit of bending in this car or should I just try to replace the universal joints?
