#54 of 61 1993 Sputtering LeSabre by 93buicklesabre Oct 01, 2009 (6:23 pm)
Hey guys I have a 1993 Buick LeSabre with 153K on the motor and tranny. When I bought the car it had sat for a year. When I got the car it started right up after I bought a new battery for it. But now 17K miles later it sputters when it comes to a stop. The check engine light does not come on. But as I am driving down the road it runs like a scared cat. It has great pick up and acceleration. But what is causing the sputtering when I come to a stop? Does it need a tune up? Or is it a vacuum leak? I am getting over 30 mpg on the highway. I have come to the end of my guessing of whats wrong with it. But help me guys.   Thanks Replies to this message: imidazol97 (Oct 01, 2009 6:43 pm)

Replying to: 93buicklesabre (Oct 01, 2009 6:23 pm) Does it sputter if you shift into neutral while slowing down? Does it stall?   EGR valve is one possibility. It can be removed and cleaned with carb cleaner. Check the tube for deposits under the EGR.

Replying to: polara60 (Sep 07, 2009 1:11 pm) This is exactly what I have done. I used a 71" belt and it works like a charm. Now the neighborhood kids don't run in fear when I turn on my road. It's (71 - 6 ) because the pulley's have 6 grooves. You'll have to use a metric 15 wrench with a pipe for leverage on the tension pulley. I used part of a floor jack - you know the part I mean ? It fit right over one edge of the open end of the shorty I used. You'll need a short screwdriver to pry the belt around the tension pulley I would suggest making the 71 work instead of going bigger if it doesn't go right on, because these belts do stretch. And you will have to pry it on. Just make sure you pry it on the tension pulley so you are against the back side of the belt and not on the inside ridges.  Good Luck.

Well I have not checked that yet. But I need to know where I can find a engine diagram for that motor to find the EGR valve. That would be great if you all could find me that information. Also just curiosity my check engine light comes on now from time to time and it stays on for about ten minutes then it goes off. It does that every 3 to 4 days. I know the transmission is still strong in it because when I stomp on it it doesnt slip at all. So I am just trying to figure out what is going on with those couple things. Thanks alot guys.

Replying to: 93buicklesabre (Oct 08, 2009 4:47 pm) Pull off the vacuum tube on the Fuel Pressure Regulator on the front of the motor. If there's liquid gasoline in the tube or you get a strong smell of gasoline, it may be leaking gasoline from the fuel line into the intake system.   The FPR is the light aluminum colored thing on the fuel rail in right in the middle of picture going across and about 2/3 of the way to the right.     EGR valve picture. On exhaust pipe on back of engine close to throttle body end. Has tube going to air intake.   Replies to this message: 93buicklesabre (Oct 09, 2009 9:27 am) imidazol97 (Oct 09, 2009 4:06 pm)

Replying to: imidazol97 (Oct 08, 2009 6:53 pm) Ok so how do I fix the problem with the fuel leaking into the intake system? I am trying to figure it out so I can fix the problem because I love the car and I dont want to get rid of it. Let me know... Thanks Replies to this message: imidazol97 (Oct 09, 2009 4:06 pm)

Replying to: 93buicklesabre (Oct 09, 2009 9:27 am) Do you have liquid fuel in the line from the FPR?
