i had one as a daily since new in 05. done 43k now imperial blue and only ever changed lambda once. iv never had economical cars so its just been normal economy to me.
but iv had a few of the common probs with them on my track car im building. mainly fuel pump issues. new pump at fords is 300+. dont bother second hand cos i bought one and it was worse than what i had. iv had a nightmare making an uprated pump fit but think iv got it sussed. cost £55 but if i had my time over i would buy a sytec pump from demon tweeks for 105. i think its a direct fit.
read my project thread if you want more info on pump.
