1992 BUICK LESABRE VIN# XXXXX

I CAN NOT FIND AN ENGINE NUMBER ANY WHERE ON THIS ENGINE, IN YOUR PRIOR REPLY YOU ASKED FOR THE TENTH NUMBER IN THE VIN.

Expert:  Gary replied 5 years ago.
ok under the hood there is a sticker that has some spec's on it if you can read the bottom of that sticker can you tell me if it says federal or california emissions.....als may i ask why you are going for the EGR valve?
Customer: replied 5 years ago.

FEDERAL

I WAS TOLD THAT WAS THE PART I NEEDED BY LOCAL GARAGE, AN EASY FIX. HA HA

Expert:  Gary replied 5 years ago.
well looking into the EGR valve it looks like some did and some didnt have egr valves...did they say what the part was called?was it the egr valve?did it have a code in it?what was complaint of why you brought it to them?
Customer: replied 5 years ago.
AFTER RUNNING AWHILE IT WOULD MISS AND STALL, IF YOU LET IT IDLE IT WOULD SOMETIMES CATCH UPAND RUN. NEW FUEL PUMP, ALT, PLUGS & WIRES.
Expert:  Gary replied 5 years ago.
ok according to all the info i have they did not use an egr valve for that car..they used a 3 way cat to clean up the emissions..so they didnt need an egr...is the check engine light on?did the garage say what part it needed?would help if we knew...
Customer: replied 5 years ago.
CHECK ENGINE LIGHT COMES ON ONCE IN AWHILE BUT GOES OUT, JUST SAID CHANGE EGR VALVE AND I COULD DO THAT MYSELF.
Expert:  Gary replied 5 years ago.
i would start with scanning the computer and see what code is in it..we realy need to start there or we will both be guessing and that costs money with tryme stuff we are here to save you money..if you could get it scanned and tell me the code we can more effectivly repair this car...let me know..hope its helping
