My 94 LeSabre runs well and smoothly, except: Almost always after it has run
for a while and therefore has wormed up, it will hesitate as if running out
of gas or spark plugs aren't firing. It kind of stumbles. Sometimes the
engine stops for half a second and then works OK again, other times it does
this several times in the space of 2 or 3 seconds, then it will work OK.
Rarely, it will stall when stoped at a trafic light or starting to go from
it. Even more (very) rarely, it will stop when going. However, it will
always start right after the stalling and work OK.
A month ago I replaced the EGR because there was a trouble code present.
It's OK now. The fuel presure is OK. No error codes present. Several days
ago I cleaned the back of the ignition module (under the distributorless
ignition coils?) and for 2 days I thought the problem was fixed, then, it
Any ideas on what may be causing this?
