Warm Start Rough Idle ’90 Olds

[mikeyb]

So, starting today, when I go out to warm start my car (start it after letting it sit for like 20-30 min) it idles rough at first, and almost feels like it wants to stall, but doesn’t. I was wondering if any of you guys know what this could be. I was initially thinking coil/plugs/wires but if that were the case, it would stumble under hard acceleration, which it doesnt. This leads me to think that it could be the fuel pump going bad, but I’m unsure…let me know what you guys think.

Thanks,
Mike

Could be a crank sensor getting hot and your loading
up with fuel or test fuel pressure. before you start
the car. cycle the key on and off 3-4 times without
starting it then try and start it. if it starts fuel
pump is suspect. I would confirm with a fuel pressure
gauge. Also change your fuel filter. Pull your vacuum
line off your FPR fuel pressure regulator and check for
fuel in the vac line or coming from the regulator.
