94 Lesabre Hesitating!

Having lagging problems with my 94 lesabre..

turned it on this morning after i got off work and it starts and shuts off...

it stayed on untill i floored the gas pedal and it stayed on.. with the service engine soon..

so i assume its a gas problem..

No, get it scanned for the code, eliminates some guess work.

Never assume it's anything. The first thing you need to do is find out what tripped the CEL. Pull the codes and post them here. Also, you need to be a little more specific as to your problem, your description is vague at best.

My Car Starts.. and it starts shaking a bit then it shuts off.. then it starts right back up and does the same thing and shuts off.. and then you hear a big gulp.. in the engine..

then i get a GAS ODOR!..

but the service engine sooon only comes on when it shakes and turns off... when it start it back up.. the service engine is off..

but i have to floor the gas pedal to get the car to stay on

pull the EGR valve.

No, I'm not a moderator, but they will tell you it is not cool to post three different posts basically asking the same question. Put all your stuff in one post if you asking about the same problem.

Correct.

I replaced the PCM.. and it ran good for about 4 hours and went crazy shaking again..

i checked my knock sensor.. and its dripping a liquid which is not gas... i put it off and put it back on and it stayed on no problem then it just shut off after 3 minutes...
