juddering problem.?

[undefined]

hi

fitted a fitler yesterday (ram air flow) and all seemed well until i went to give the car a bit of a thrash and it startedto judder.like it was hesitating an then it would be fine for another 2k on revs and then it would do it again.. no pattern and im not totally sure ut i would say it was when i was on boost.

now what u reckon...
-MAF's ****ed
-too much air flow
-too little air flow
or summat totally different.?

cheers

i know i originally thought that but a mate mentioned last night that could be maf..just seemed a coincidence thats all. iv had a misfire on cylinder 1 on idle 4 a while so maybe it is the coil pack finally goin...

mines a really bad jerk and i need to get it sorted asap.!

its not the coil pack after all that and changed the plugs today.
pressure test 2moz and hopefully if its not that its time to change injectors around and see if misfire swaps from cylinder 1 so another.?

if not could be a costly repair...

Un-plugged the MAF to see if it runs any better? Was the filter oiled? If so the oil could have hit the MAF and fried it seen it happen before. If so check your receipts as the MAF is new and could be taken back to any Euro Car Parts brance with a little sweet talking.

if youd just changed the filter then i would say maf is causing the problem

i there ive only owned my ibiza for 2 weeks now and i had the same problem when driving normal it was ok but when i put my foot down on the moterway it was missing, it turn't out to be the airmass sensor. so i would look into that
