l had a scan on my corsa because engine management was on, the errors found were codes 33 and 35 map sensor and idle air the mechanic sad l should be able to do these myself, which l am keen to do but l just wanna be sure first so l would like to get a free download or if someone could email me a diagram l would be grateful. they are all based around the carb so a diagram of this section would be helpful.
cheers
1995 1.2 engine

just because the two codes came up that does not mean that the sensors are defective..be fore u replace these parts, l would find out .also u have a throttle body not a carb...your iac could be dirty,map may not have proper vacuum to it
