I had my 89 3.0 5spd parked at work for a couple months because I have been pretty busy and had just been driving the work truck around.

So I go and fire her up yesterday and it started up ok but pretty much instantly started struggling and running rough, then died. Tried again, same thing.

It will not stay @ idle. If I keep my foot into the throttle it will run fine, at least from around 1600 rpm and up. below that it is still running rough. When I drive it and put foot into it, it runs fine. again, anything over 1600 rpm, runs great. But if I so much as clutch it for more than a few seconds it will die, unless I keep the revs up.

I'm gonna try and diagnose after work today. Just figured I'd try and get some ideas of where to start.

Any possible the fuel went bad on me? I had about 3/4 of a tank in it when I parked it.

Thanks in advance for any replies/help/ideas.

 

check for VAC leaks first check the intake hose from the afm to the Throttle body for cracks or loose hose clamps.

 

smarty pants.

It was my intake hose, clamps loosened right off and was pretty much just floating on there.

thanx for help
