Question about 1995 Cadillac DeVille

1 Answer

I am having problem with my 1993 Cadillac DeVille. It begins to shudder and shake while driving or stopped in traffic almost to the point of losing all acceleration. This problem seems to come and go without notice. I've changed plugs, wires, distributer, cap, rotor, and fuel pump. What now?

    We had mechanic change out the ecm and it resulted in a the car running even worse. He stated that he possibly need to buy the software that might rectify the problem and that was not a sure thing. Any ideas? We've poured a ton of money into this and just wonder if it's worth it. Thanks for your help.

Not fuel related...
The engine is losing ignition timing.
It sounds like the ECM (Electronic control module). It is responsible for ignition timing.
Inspect it / replac eit.

Where is the crankshaft sensor on my 2006 Renault traffic


diesel as no petrol models made anymore,2.2 litre engine if my memory serves me right ,seem to remember its underneath on the bell housing ,These traffics can be tempremental and drive you mental when you have a fault ,or is it a 2.8 anyway know its the smae engine as a vivaro and they develop the shudders change the flywheel and that doesnt always cure the shakes or changing the drive shafts although the rear engine mounting is often the main culprit .sure the crank sensor is underneath on a vehicle of this age ,some were in the block just above the sump rail or am i getting confused with the zaffiro ,sorry old age is my excuse here

I have a 2000 caddy deville. my moter shake only when im stopped and not when i drive. i did a tuneup and it still shakes. can i be a bad coil pack or.......?


try checking the throttle body and look for lose hoses anywhere near it it might be a lose EGR valve anywhere near the throttle body. when disconnected or gunky or just plain out broken EGR's will cause the car to have a very rough idle.

Did you check the condition of your motor mounts? Since it seems to vibrate in idle, that might be your problem.

I just changed brake booster out got new one from junkyard. When I started test drive it was like the brakes were halfway applied. Before i got to the end of driveway it stopped by itself. When I cut car...


The booster should be right if it came off of the same model Cadillac 93 Deville. I would return the booster and try another one. Probably the master cylinder is ok if it stops.
