I have a 95 astra 1.4 Merit. Problems of hot starting have gradualy got worse from only happening in hot weather to cold weather. I have been told its probably the air intake temp sender but I cant get the part in local scrap yards or on ebay. It has a brass nut and screw thread as part of the body o the sensor Photo here. [URL]http://community.preloved.co.uk/forums/discussion/80465[/URL] Somebody told me this has a resistance of 2k when cold which it does and 400R when hot. as I cant get the part Im thinking of switching a resistance in parallel to the sensor to bring it down to 400R when I try and start it hot. Then switching it out when starting cold. I would appreciate any response about if this might work
