so, some of you may remember. a while back while looking for a new second car I stumbled across a 02 deville with a salvaged title for $300.
i decide against buying it because of the salvaged title but I now had the bug... i would of preferred a seville but found the deville's being more in the range I wanted to spend - under 3k.
i figured I could find a deville needing work, under 130k mi, for under 3k.
i paid 2k for a black 03 deville base with 119k on it. interior looks great! exterior not so much....
at this point I have probably put more money into it than it is worth but this is what I did
got the front an rear bumpers replaced and painted. (know a body guy, got a good deal) the body guy also installed new engine mounts and o2 sensors and new shocks.
i installed:
new struts
new valve cover gaskets and spark plugs
new rubber intake plenum coupling
(cleaned the whole intake plenum and throttle body)
new idle air control valve
the car runs pretty nice now. getting about 20mpg
i have some questions I'd like to request your feedback on please:
should I be getting higher mpg? I do a lot of highway driving. fueleconomy.gov says 16/25. I was hoping to see 23mpg regularly. On an all highway 70+mph trip, of 1 complete tank, I saw 22.9mpg (OBX trip, yeah!!!). but otherwise I am seeing 20.5mpg regularly can I get higher, if so what could be the cause of getting this low?
99.999% of the idle issues where fixed when I replaced the intake plenum coupling. But there is sometime a slight idles inconsistency usually when the AC is on. The car can idle as low as 600rpm sometimes at 725rpm. Sometimes it just goes up and down between 600 and 725 while idling. Also sometimes when I come off the brake the idle is so high (often coming out of park) that the car jumps forward too fast. Also I get the sense that sometimes while driving at 40 the rpm are jumping up and down, I can see the rpm display going up and down between 1200 and 1600 but I'm not really giving it more or less gas. what could be happening here? (im thinking some rpm sensor or?)
please also let me know what are other common problem areas with this car? are there already threads about these things that I am not seeing in search?
overall I do love this car!
thanks
