  1. Idle Speed Actuator for sale?

    Alfa GTV & 916 Spider
    Hi all, It seems the idle hunting issue I reported earlier hasn't really been resolved, and I might be in need of a new idle speed actuator. The scary thing is that they're not made any more! Does anybody have a spare they're looking to sell, or can point me at a resource that has? Thanks!
  2. Idle Hunting - but only when slowing down in traffic!

    Alfa GTV & 916 Spider
    Hi all, I’ve got an interesting one this evening. I’ve noticed the GTV (2.0 TS) starts idle hunting when I’ve got the clutch depressed and I’m coming to a stop, but then idles just fine when actually at a complete stop. Any idea what this problem could be? I’ve recently replaced the RPM sensor...
  3. 96 GTV V6TB idle issue

    Alfa GTV & 916 Spider
    Hi guys, after changing my cambelt i had a lot of issues with my engine. I managed to sort out most of them and now my engine starts and runs, BUT idles really funny. When cold, it starts normal, but the idle is crazy. It revs all the way to 3k rpm, then drops to under 500 rpm (sometimes...

  5. Alfa 155 with later engine hunting idle problem

    Alfa 155
    Hi I've got a 1998 alfa 155 2.0 16v. I think its the later engine that was taken through to the 156 and GTV. After the car is warm, at rest the revs rise from 1000 to 200 and back constantly. Also when I take my foot off the accelerator the car slows gradually but sometimes jolts slower still as...
  6. 159 2.0 JTDM idle consumption

    Alfa 159, Brera & 946 Spider
    Dear All! I've noticed, the initial consumption of my car won't get below 2.0 liters/100 km. I haven't checked the OBD reading so far but during engine breaking, the consumption should be 0 liters, because there is no fuel injected into the engine. I'm wondering what is the case behind this...
  7. MA TCT 170 - Hunting idle when climate control off and a strange whistling sound

    Alfa Giulietta
    Hi all, I am quite new to the forums, but I'm hoping to get some advice from other Giulietta owners. I bought my G TCT QV Line 170 MA in September last year and my partner and I absolutely love the car, but it has recently developed some niggling issues, and one of them making the car annoying...
  8. Help - battery icon & rough idle

    Alfa 159, Brera & 946 Spider
    Hi all. I'm hoping somebody can help. I took the brera (2.2) out of the garage for the first time in about 2 weeks and after 3 or 4 miles of driving, the battery icon started blinking on and off. I kept on driving, parked up at work and hoped it would just clear itself. The car started fine 8...
  9. GT JTS - idle control valve P0505

    Alfa 147, 156 & GT
    So this fault code appeared yesterday, cleared the fault via MES, havent appeared again as of yet. I am led to believe there isnt such valve on the newer fly-by-wire types of throttle control. The valve is part of the throttle body here (?). So the only option for me is to try to carb cleaner...

    Hi everyone, I was visiting family at Christmas and the subject of my (new to me) Alfa 159 TI 2.4 JTDM came up and my step dad mentioned "whatever you do, alway leave it idling for a minute or two after you start it and just before you switch it off" so I humoured the old man and have been...

  13. Alfa 156 JTS wont fuel trim at idle

    Alfa 147, 156 & GT
    Hi! A 156 JTS has had its engline worked on (and thus had its battery etc. disconnected) has lost its ability to fuel trim depending on the lambda reading at idle. It trims fuel efficiently at +1200RPM and there are no fault codes either on the dash, or stored in the ECU. Obviously the...
