Fuel Injection Warning Light
Sorry to butt in on your forum, but I thought I might find some clever chaps here....I have a GTV 3.0 V6 (Phase 2, year 2000).
A few weeks ago the Fuel Injection Warning Light came on. I took it to the Alfa dealer who diagnosed a problem in the "accelerator line". They fiddled about and the problem went away.
Now it's back on again. I took it to the dealer again and they said they didn't really know where to start fixing the problem, but that it is definately in the "accelerator line" ! It also looks like it has had a new throttle potentiometer before.
So they suggested they replace the throttle potentiometer for starters, as this was the cheapest option to start with ---- at £497 !!!!
So can anyone please answer the following questions:
1. Do the throttle electrical cables run directly from the throttle potentiometer to the throttle body (at the air intake) so that I could test them for continuity, or do they go via a computer ?
2. Has anyone managed to service a throttle potentiometer or throttle body or are they completely sealed units ?
3. Are there any other parts that might be causing this problem. (I know the Air Flow Meter can cause a fuel injection warning light problem, but is this actually in the "accelerator line" ?)
I'd really appreciate any advice.
