SO yeah, i spent like 4 hours yesterday working on getting my 1j to start. For some reason it would only boost to 4lbs and then would have total fuel cut. Super horrible. Well it took a few hours of testing to figure out that the MAP sensor was actually malfunctioning. It would only go to 2.66v. I couldnt get it to go over. 2.66v is equal to about 4lbs. Well, we kept blowing into it and testing it for like 2 hours. We were able to get it to go upto near 5v with the air compressor, so it would go to about 4.5v, but then we would drive it and it would be limited to 2.66 again. Fricken innoying. Well, finally after 2 hours it stopped acting up and i was able to go to full boost. I have no clue what on earth was going on. Have any of you had similar problems? Is there another map sensor that can replace this one. I cant imagine that there isnt another option. It is a very simple map sensor. 2.5 is zero lbs and 0 equals to about -20lbs of vacuum and 5V = about 20lbs of boost. Well, let me know if you guys have any ideas. Do these map sensors go out very often? I drove her all night and it was FRICKEN AWESOME!!!
