Weird Idling Problem And Fuel Smell.

[CeJay]

Ok I've had a bit of a weird problem for the last few weeks, had the car service a few weeks ago, they cleaned the aac valve, which stuffed up the idle. Readjusted it, which seems to have made it a bit better, but it was still there. I then replaced my pod filter, as I had ordered a new one before, which improved the idle even more. But I am still getting a constant fuel smell in my car. I have a ecu talk lcd display, and I'm getting no codes.

The idle problems only seem to happen when the cars warm now. I can't see any leaks as far as I can tell. Does anyone have any pointers for me? Before I book it into a mechanics to get checked? Also my fuel consumption has increased, but like I said, still no codes.

Now would replacing the aac valve solve this?

thx

eh? I hate that... when someone else does the work and you don't know what's been done.

There are a bunch of vacuum lines around the AAC valve housing, so if one of those were split or disconnected, you'd have a rough idle.

Did they replace the seal for the AAC valve housing?

As far as I know, no. Its only idling rough in the middle of the day now, when it's like 35 degrees, on startup etc it's fine. The problems really intermittent now, sometimes it's ok in the middle of the day, it's just plane weird atm.

How's the timing? When it's warm, mine will settle down to 8-9 degrees BTDC.

Can you unplug the AAC sensor and check the idle again? i.e do the idle adjustment yourself. I suspect that if they didn't unplug whatever sensor it is that needs to be unplugged, they may have adjusted it for when it is cold?

I use consult software, and when you choose the idle adjust option, the idle will drop if it's cold, or increase if it's warm. More to the point, the timing should be exactly 15 DBTC on an R33 (check what yours should be) Oh... I think it's the TPS you need to unplug on an R32. (but again, check first, i'm just guessing). So when the correct signal is blocked, and it's running the base timing, you can adjust the idle to 650rpm (again, R33, check what the R32 should idle at).

If you can basically redo the adjustment for your car, i'd be keen to see the results.

Thx I'll have a look and see if I can hook it up to my laptop as well. See how it turns out, thx for the tips.

check injectors for leaks when running
