Just wondering if you guys might be able to help. The car drives fine and the engine will start and run fine when its cool. If the cars sits for a couple hours it will start no problem. When the motor warms up and you stop the car and restart, thats when it stumbles and has a hard time starting. If you let it set for a while, it will start fine again.

Anyone have any idea? It it not throwing any codes and no CEL

 

i have seen this many times the fuel regulator is bleeding back in the fuel rail and flooding the engine some times the cel wil lset for a ramdon miss fire. pretty common thing.

 

so you think I should swap out the regulator?

 

since it is a known problem it could not hurt. has their been any dtc's stored ?

 

93 legend? lol. headgaskets, dude.

i'm not saying that's what it is for sure, but i've seen more than a few come in with runnability problems, and sure enough.. headgaskets.

if you do them, make sure to get the knock sensors unplugged or you'll break 'em. real easy to do.
