I'm still pretty new to Alfas and this incredible community, but you all have been a fantastic help already. I'm hoping you can help me problem solve another issue with my 84 Spider.
The car runs great, but I've always known it runs rich. I took it in for an emissions test (I don't need it - exempt in Utah), and I was really surprised at the results. All CO numbers were great (.74 idle, .72 loaded) and the loaded hydrocarbon (HC) number was good (104); but the idle HC was 1508 (220 standard)! So, I need some advice problem solving.
What I know or what I've already done:
-Engine compression is good - 125 across the board (dry).
-I had already suspected a vacuum leak so I replaced all the vacuum lines - however, I'm not sure about the injectors leaking (air).
-Plugs are new - I'm not sure about the age of the wires, but they look good.
-CAT temps are good on the in and out sides. Not sure about O2 sensor.
-I replaced all filters - air, oil, fuel - and fluids.
-No noticeable misfires.
The car really runs really well, but that HC at idle is far too high. Ideas?
I went through this with my ‘85. I believe you have 1 or 2 problems. First it sounds like the diaphragm in your fuel pressure regulator may be toast. It’s an easy check. You may find, as I did, fuel flowing from the air side of the regulator. It’s an easy fix.
secondly it sounds like the o ring in your idle circuit is gone. Over the years they start to take a set. you can get some very bad advice about finding a replacement. I’ve frequently read advice about getting some close from the hardware store. Rubbish, you won’t get an o ring to fit and they won’t be formulated to work in gasoline environment. Remove the old o ring from circuit, measure it and then get the correct item from the o ring store. Install it correctly and you can begin to regulate your idle.
I disagree with the advice about adjusting the idle at the air sensor. That adjustment is sealed for a reason and you should never have to play with it. I’m equally at odds with adjusting your cams or replacing the O2 sensor with a 3 wire system. You can easily check the sensor.
Okay, so I finally located the source of my 150mA current drain that's been killing my battery. Fuse #5, which controls the blinker and hazard relay, and the radio, has shown itself to be the source. I pulled the relay and was still getting the draw. So I pulled the new Pioneer radio that the...
I am looking to refurbish the rear bumper on my 1978 Spider 2000 Veloce. I've added some photos of the damaged rear bumper. After some research, I found a brochure that shows a bumper with a chrome inlay piece. The only problem is that I can't find this inlay piece on any (European)...
I picked up a couple of vintage 'spider veloce' front fender emblems on ebay to install on my 89 Veloce, but now realize I have no idea how these are attached. It would be some sort of adhesive, but I don't know if it would be a double-stick tape, or a silicon adhesive, or some other glue-like...
I have the usual problem of wipers not parking and I understand some contacts on the washer foot switch should be normally closed? Can you advise which please. All seem to be O/C
Pic is attached - I can't see any contact numbering on the unit
Also, one of the water inlets is split - I...
My clutch hard tube (running from clutch master cylinder to clutch hose) sprung a leak. So I need to replace that. While I am at it, I am replacing the flexible hose that runs into the slave cylinder.
Below are 2 photos, that lead to 2 questions...
Photo one shows the new hose from...
