94 fleetwood idle prob.
I have a 94' fleetwood brougham with the 5.7 with the performance chip. Also, all pollution control has been removed. Dual exhaust with blow-through cats. Aftermarket computer to run it stripped down like it is. Its been trouble free for the last year or so, but sometimes it just dies at idle or no excelleration like if pulling into a gas station. I can tell when its going to do this by the way the idle seems low. If I'm running the a/c, the fan will also slow when pulling up to a stop. I have 3 guages on the 'A' pillar. Water temp, fuel pressure and air/fuel mixture. The air/fuel mixture leans out alittle along with fuel pressure drops a couple lbs. If the car stalls, it starts right back up on a dime, but may continue to act this way. But most of the time the car is great with no stalling. I would like some other opinions on what this could be. I am thinking maybe fuel filter ... or maybe the pump. But the car never boggs at any excelleration or start-up .. so I'm not sure if its a fuel issue or maybe the chip or cpu.
