Question about 1992 Cadillac DeVille
Car idles rough,has a loss of power, and skips a little bit but doesnt backfire or anything like that. Its like a sort of mis-fire but i replaced the spark plugs, wires, dist. cap, ign. coil, TPS, EGR,MAP sensor, added injector cleaner, and cleaned the throttle body......All for NOTHING.. None of that fixed my problem. I did a compression test and ALL cylinders are good....What could it be?
Hi,you can run a fuel presure test to see if the fuel pump is working properly, you can also run a timing chain text ,this is a little complicated but you may be able to do it , take the distribuitor cap off,with a ratchet turn the crankshaft back and faward,if the rotor takes to long to move the chain is worn out,this can cause loss of power, I hope this will help.........
