2003 exp 5.3 V8, cat problem?
My 2003 expedition started running rough and stalling a couple weeks ago...it had a lean code which the PCV was bad and after replacement it idols better and does not Stall , but it may still need tuneup because The service engine light is on and has blinked on occasion? The thing is I do have a vacuum leak in the brake booster and there is a pinging sound sometimes which I think is coming from the Catalytic converters 😕
it seems to be underpowered and shakes driving down the road...I do need tires so I wasn't sure if it's the tires or the engine causing it to ride like an old lumber truck.
what do you guys think? I'm low on $$$ right now too 😬

A flashing CEL means there is a misfire severe enough to ruin the cats. When flashing, the engine should not be run any longer than it takes to get to safety.
