i recently bought a 1990 sc 5sp only 70,000. i gotta a pretty good deal on it because the guy couldnt figure out what was wrong with it. after replacing a few sensors it ended up being the cam sensor and one of the plug wires was melted..now it runs and drives good but only if u unplug the mass air sensor and iac.. ive bought both iac and 2 new mass sensor and still nothing. if there plugged in the car will hardly run and will not pull its self and idles like its cammed. it acts exactly like a bad mass air . the previous owner said when he got the car some idiot had the red wire from the mass air plug wired to the fan... any advice would help thanks
