Question about 1994 Buick LeSabre

2 Answers

My 1994 buick w/3800 engine suddenly started "stumbling" and not running above an idle. when it does run for a little while, when you try to accelerate it "bogs" and if you try to push the accelerator it just won't take the gas. i had to drive on the shoulder of the road to get home, in drive at about 10 mph

I would put a new fuel filter on and try that. If that didn't work, sparkplugs and wires, and a distributor cap and rotor. Also make sure your air filter is clean.

I meant how do you replace an egr sensor in a 2005 rendezvous?


A faulty egr would not create a high idle issue. if an egr valve were to open while idling then it would create a heavy stumbling engine or it would die right out. if there is a check engine light on (or service engine soon light) have the codes pulled. Failing that then I suggest taking it to a reputable shop

94 buick lesabre 3800 engine, stalls after 10 mile drive and will not start till cools. replaced TPS, Fuel pumpand filter, cam sensor, crank sensor, and ignition control module.


next time it won't run after it heats up, spray or pour water in crank sensor and see if it will start. I have seen new crank sensors go bad.
