hi all,i seem to be having a issue with my cars map sensor.my car is a 98 civic
dx that keeps giving me a code 3 and only a code 3.i replaced the map
sensor with a borgwarnner sensor, but i keep having the same issue. so i did
a search on HT for post on the same issue and i came across a couple of post
that advised me to check the voltage the map sensor gets.i did and according to me the sensor is getting 5.5 volts.so i replaced the ecu with a good used unit
but i still have the same issue.the funny thing now is that when my car starts acting up its not as bad as it was and only seems to show up when the weather
and or cars operating temperature start to clime.any help is much appreciated,thank you
