hey im having quite the same problems with my 94se. the only difference is that mine is marking the knock sensor and a leak in a injector. so i went along and took the heads off and did all that and my knock sensor was melted due to, to much overheating.. so i just went along and bought a new new knock sensor and all 6 new fuel injectors. i later then found out one of my heads were bad cause i took them to the machine shop and its what they told me.. so now ima put briefly about 1200 dollars in work.. but once im done putting everything back together ill get back on and let you know how everything turned out... so i say check your knock sensor make sure its still good..
