87 suba gl FI 4wd;

 

When I start it or idling there's pretty low pressure oil pump (0-5psi) also rough idling too.

 

But running to drive city/hwy there's good oil pressure (45psi)

 

I did repair oil pump gasket..

But you think need repair oil pressure sender sensor or oil pump.

 

Heres' video.

Thanks

low readings at idle are common.

I dont understand what's you mean a common? It's low psi when idling plus rough.

next to sero readout is normal during idle. if the engine runs rough, suspect other issues. perhaps the timing is off if you had the belts out

Actually already installed new timing belt kits & oil pump gasket. You mean camshaft sprocket's tooth off?

Yeah, I was test oil pump pressure test was good psi.

But I don't know why still rough idle and pretty low rpm before die. I was put adjuster more fuel/mixture on crab/FI for avoid to low rpm...
