Further to my posting a few days ago concerning an r.p.m. problem on my daughters punto 1.2 8v 2001, i have now discovered the throttle position sensor is faulty. I am running the car with the t.p.s. disconnected and it runs fine, however i do need to change it. The only ones i have seen on various sites are the screw on type at about £12 each, this one is pushed into the air intake housing does anybody know how to change it? Thanks in advance
