Anyone have any ideas?
I recently bought a 1985 oldsmobile 98 at an auction, it's in really good shape with only 125000 km on it, with a 3.8 fuel injected engine
The problem i'm having is it won't stay running when it's cold. When you start it, it will run for about a minute and then stall unless you stay on the gas. When it does stall, it will start right up again, but you still have to stay on the gas until it warms up.

So far, i've had the fuel pump changed, and the intake gasket replaced. I've sprayed the throttle body with cleaner, and removed the high idle valve and sprayed it down with cleaner, but the problem still persists.

Of interest: I knew of that exact car owned by my parts store owner - demo (year old or so) and it idled annoyingly low - would vibrate the car! Back to well known dealer a few times and it was written off as normal and it didn't stall but seemed like it would all the time. Idle isn't supposed to be mechanically set and the computer setting just wouldn't allow to raise it just a tad.

Been a while - I think I found an adjustment to something on throttle body or idle speed motor just to kick it up 100 RPM as the rock bottom base idle and it stayed that way just fine for 20 years more with no problms. It was just that year and that car - not the others. It was the first year for the FWD '98 - right? Just a thought - the one I dealt with didn't stall,
