I have a 1990 chevy k1500 that for the last week and a half has been running horribly. it started with just code 33, so i replaced the MAP sensor. it now is running codes 15, 22, 24, and 33. cant seem to understand what is going on with it, but it went from getting about 16 mpg to about 5 mpg in a week. the codes are pointing me to a bad ECM seeing that ALL of these are just now showing up, or a bad/maladjusted TPS sensor. can anyone help me with this? i cant stand having my truck run like this
