Hesitation when accelerating - split pipes or MAF?!!
I have searched loads on hesitation/juddering when accelerating and the MAF/AFM and whilst the info has been really helpful, nothing seems to address my problem exactly - would really appreciate some help!
I have had a 1999 2.0L Spider 4 months and when I take it out on longer drives and put my foot down, have noticed a hestitation/loss of power/juddering feeling at about 3500-5000 rpm. It is worse in lower gears (2nd the worst) and always worse on a hill start. If I accelerate gently I can avoid it but it's really bad when I put my foot to the floor. It rarely happens when cruising along in 5th at 70-80 mph.
I'm trying to decide whether to disconnect the MAF and take it for a drive to see what happens but am confused about a couple of things!
Have just been down to have a look at the AFM and can see a load of small, ribbed pipes coming off the top which then wind around to the top of the bonnet and are connected to what looks like a fan type thing. (Can you tell I'm a novice?!) These are completely cracked and have clearly been tied up with bits of rag...there are about 9 or 10 places where this has been done.
Could these leaks cause the problem? Are these pipes even related to the AFM?! Is the AFM and MAF the same thing?! If the pipes are the problem, is this a huge and costly issue to sort out?
I have been told by an Alfa garage that if I disconnect the MAF and take it out, I then need to take it to a garage to be put on a diagnostic machine to erase the fault code and turn the warning light out. Is this true? I have read on here that starting it 6 times will solve the problem but not sure what is right? (At the moment there is no warning light on)
Basically I am confused! I don't want to disconnect the MAF and have to take it in to get 're-set' if that isn't the issue. But equally, I don't know what these pipes are and if they could be causing the problem!
Any advice/thoughts are much appreciated, thanks.
