Have you checked the fuel system? Maybe a clogged fuel filter.

Sounds more like air/vac leak to me if you can maintain running at higher rpm.

i looked over the fuel system it seems fine i will check the engine over where should i start to look

[black rocket]

Vac hoses, intake leak, but I'd ck vac lines really well.

Good to hear things are fine. That damn 80 amp fuse, I have replaced that three time on my 88 SE.
