Hi. This forum has been very helpful since I bought my GT a few months ago, but I can't find an answer for my current issues. A few similar-ish ones, but not specific. I'll post them both here, because they may well be connected.
1. First, I have experienced problems starting the car from the start. There's nothing consistent about it though. I have never had it happen when the car is in my drive, but nearly every time I go into town, it happens. Sometimes it will turn over and turn over and then manage to start; sometimes it will fail entirely to start. But it's never failed a second time. The angle the car is parked doesn't make a difference, nor the amount of fuel, as I've seen suggested elsewhere.
2. Second, the car has little acceleration in first and second gear. Even with the revs up around 3k, sometimes. I have pulled out in front of cars or tried to overtake before, thinking I had plenty of space, only for nothing to happen when I put my foot down.
As for what I've done about it so far... I cleaned the EGR, which gave me a little bit of power back, but not much. Then I recently took it to my mechanic - an Alfa specialist - and he put in a new EGR and replaced an air intake pipe under the battery (a big tear in it had been taped up), telling me that would fix both issues. It made no difference whatsoever. So now I'm down £255.
I don't know enough about cars, but I'm wondering about the MAF and the crank sensor. Any other pointers would be appreciated. Thanks
