Question about 1984 Cadillac DeVille

1 Answer

1984 CADILLAC DEVILLE LIMO WITH 4.1

It runs, has new cap, new rotor, new spark plugs, has a slight miss still but not real bad. The problem is when I put it in gear it has no power, and I have to feather it to get it to move. Can you please give me some ideas of what the problem could be? Thanks!

This sounds like you have a vaccum leak. The most common spot to check is the base of the intake. An easy way to find it is to start the car and 'carefully' spray either in this area. you will hear the engine pickup a bit when you hit the spot! Replace the gaskets as necessary. Also check that vacuum hoses are all attached. Frankster016

Tuned up car changed 02 sensor full tank of fuel still running rough


Oxygen sensor only report the condition of the engine the rough running condition can range from a worn sparkplug wires to worn sparkplugs to valve problems to injector problems. with the cadillac deville a tune up should be the first attempt to smooth the rough idle with the inspection of the cap and rotor cap and rotor do have a tendancy to arc internally and create misfire so does sparkplug wire that can leak spark voltage to ground and create misfire. the spark plug wire especially if they are brittle and hard can create issues

I need to find out the right order to put my spark plugs the firing order its a v 8 4.1 litter my brother got them all mixed up.


The firing order for a 4.1 V-8 is 1-8-4-3-6-5-7-2. Odd number pistons are on the driver's side, front to back and even numbers on the passenger's side front to back. The distributor turns counter-clockwise (backwards) and #1 piston is at 1 o'clock (close to the firewall). Hope this helps.

A faulty map sensor will make it run rich and so will a bad or misadjusted TPS but it should try to crank. Check mat sensor. A stopped up converter will do this to.
