I'm looking at buying a '99 S70 AWD, however it has 1 problem that I'm not sure of the cause.
The car has a bit of an idle hunt from around 600-800 RPM. This happens all the time. If its in park, drive, AC on or off, etc.
I'm hoping to drive it over night tonight and get under the hood. Any ideas what to look for?

by the way, the other items is needs is: Strut mount bushing, heater core, antenna mast, and maybe a wheel bearing.

how many miles on the car? could be the ETS...

how many miles on the car? could be the ETS...

107k. I had a hunch it could be, but no check engine lights.
Looks like I don't get the car all night, but for about 2 hours (in about 4 hours).
I'll check anything suggested, I just need suggestions.

open up the hood, and look at the throttle body (it's more or less under the intake manifold) if the sticker is white, it has never been replaced, if it's yellow, it has been replaced.

Mine would do the same thing. When I had the ETM replaced it fixed the problem.

How'd you get it replaced with no CEL? (or did you have one?)

there is no CEL, it's the ETS light. and IIRC, rob had his done before the recall?

ETS light. Hmm... didn't know there was one, but it's my first 99+.
Should I expect it to light up before the car starts (like everything else)? If not I would assume bulb failure (or removal... seen it done).
If there was no light, but it had the "white" sticker, could codes possibly be stored? I know an indi with Vadis that would check stored codes for $25.

the light will come on when the car is first started.



however, the light may or may not come on, it's dependant on how bad the ETS is... we had a car on the lot, that exibited all the classic signs, but the light didn't come on until about a week later.

call a Volvo dealer and give them the vin and they can tell you if the ETS needs to be done. thats what i did and it was fixed for free. try that.

[jb7073]

Got the car home. White sticker on the ETM. Also, set a CEL on the drive here. Of course the cable to the code reader is in my car...
Also, the air intake for the ECU was cracked, and I noticed some other wire looms were cracked too. I'm thinking heat and age, but correct me if wrong.

Current list of things I found it needs:
1) Heater Core (or leaking hose on engine)
2) Wheel Hub (at least 1 wheel) (how do you test to be sure?)
3) Strut mount bushings
4) E-Brake pads (or at least they sure won't bring the car to a stop at 20mph)
5) Antenna Mast
6) Air filters

not worth it
unless you're getting a ridiculous price for it

[jb7073]

Ok, after looking at it, I've pretty much decided its fair for the price. The repairs I can handle.
The code ended up being P0455 which I guess has to do with the evap. Before I knew what it meant, we agreed that if it had to do with the ETM, then obviously it would be covered by the dealer. And if it was something else, he would fix it.
Just waiting on him to call me back today after taking it to get the codes read at a shop.

If e-brake is acting up, be sure to check the brake cables - from where they exit under body just ahead of rear wheels, to where they go inside of the rear brake assembly. I expect you will find several breaks in the plastic sheathe, and those breaks let in moisture that binds up teh cable movement inside. The AWD set-up puts much more strain on the cables and they fail more often from breaks. Cables run about $40 each side, but are a major pain to replace since they run all the way up into the center console, and require disassembly of the rear brakes (unlike the FWD's)

My car had the same idle issue when I bought it.Cleaned the ETM/throttle body real good and it's been fine ever since.Never had the ETS lite even flicker on me tho,and I put up with the irratic idle for 6 months before I dealt with it.

I would agree that I hope the car has alot of redeeming qualities and a great price,because even without the ETM,there seems like a lot of things that need fixing.Good luck.

Update: had the codes pulled at a shop and the p0455 came up (big suprise), but also an ETM code was stored. Looks like I might be getting it replaced anyway which hopefully will fix the idle.

Car has a good price and is available in my area (hard to find). I also am more pickey and know more about the car than most buyers would, so I pick up on the things. Everything is stuff I have done before or can so, so the repairs don't bother me. I've already gotten more off the asking price that the repairs will cost.
