View Full Version : 2000 Deville shakes at Idle, No DTC's

My car has recently started to run pretty crappy. I have already done the plenum and intake gaskets as well as the injector o-rings. I have no codes other than a convertor code which has been there for two years. In the absence of codes, what do you guys think I should check? I appreciate any and all help..Thanks..
How old are the plugs? Did you clean the TB? Are all the vacuum hoses tight?

Yes the vacuum hoses are tight and I cleaned the TB. I did the plugs about 55,000 miles ago and used the AC Delco ones

I also cleaned the Idle Air Control valve. I guess I'll be throwing parts at this car too..Even if I take it to a mechanic they gonna do the same thing because theres's no codes to point them in the right direction..I have seen it happen all too much...
You could go to a junk yard and pick up a used ignition cassette cheap and swap them out one at a time to see if that solves the problem.

Yeah I think that's a good idea.. I just may do that
