I took the fast idle thermo valve out, and tightened the insides back up, put it all back together and it did not solve the problem. I then went to the junkyard and got another one, made sure the insides were tight on it, and threw that one in, didn't solve my problem. I am now getting engine code #5, MAP sensor. I got 2 different ones from the junkyard, and although it changed the idle, it didnt fix it. I just went out and spent 75$ on a new MAP sensor, and this made it run worse than it has before.... what am I doing wrong, I am negatively progressing!! Is there a time period in which the ECU must learn the new MAP sensor, although its OBD1 so i doubt that..
