89' S-15 Jimmy 4x4 With the 4.3

I have a small problem....

Oil pressure gauge is bouncing and keeping the chech gauge light on the truck is running fine from the look sounds and feel, anyone have problems with sender or dash cluster????[:-]

And anyone know any good site for body parts????

 

Try posting this up in the Chevy silverado forum. More chevy guys will see it in there. Don't personally know what the problem is myself.

 

usually the sending unit itself....changing it is about the best diagnosis
