1990 Sedan Deville stalling on corners

Hi guys...it;'s me again...the clueless boy wonder

So i fixed all the issues with my computers but now i have a rough idle....The car also stalls when going around corners.... I replaced the wires and spark plugs, cap, rotor...etc....

No codes come up when diagnosing it....the wires helped a little bit with the idling but doesnt help the stalling around corners.....any help would be greatly appreciated as I don't feel like getting rid of my caddy.

Thanks in Advance

I'll bet it only happens at 1/4 tank or less, right? Loose tank baffle. Turn the corner and the gas sloshes to one side. Fuel pump sucks air and the engine starves out. Replace the tank or keep it above 1/4.

i have to check on that Ranger.....i try not to keep much gas in the car because the mileage sucks....i'm probably getting 9mpg if that now

Thanks

might have a short in the pump line, especially if you have been running the tank empty for a while

Leave the injectors alone unless it is running badly. Check for a leaky FPR.

whats FPR? Fuel pump relay?

Fuel Pressure Regulator. See the Tech Tips section.

Search these forums for ISC problems or adjustment. The ISC should keep it from stalling so something is wrong there. You already cleaned the EGR tubes right?
